+# Docker Build Environment Plan for VitaSDK (PS Vita)
+
+**Status**: Planning / Research  
+**Last Updated**: 2026-01-27
+
+---
+
+## Overview
+
+PS Vita homebrew development uses **VitaSDK**, a completely separate toolchain from devkitPro. This requires a different container approach but follows similar principles: extend official base images and install all available packages for a complete development environment.
+
+**Key Differences from devkitPro**:
+- Separate ecosystem with its own toolchain (vita-toolchain)
+- Different package manager: `vdpm` (shell-based) instead of `dkp-pacman`
+- Different build system: CMake with Vita-specific macros
+- Official Docker images: `vitasdk/vitasdk` (not on devkitPro organization)
+- Output formats: SELF (executable), VPK (installable package archive)
+
+---
+
+## PS Vita Platform Capabilities
+
+### Hardware Features
+- **Networking**: ✅ Built-in Wi-Fi (802.11 b/g/n)
+  - Optional 3G modem (discontinued in 2013, limited availability)
+  - Bluetooth 2.1+EDR
+- **Screenshots**: ✅ Native system-level screenshot capability
+- **Cameras**: ✅ Dual 0.3MP cameras (front and back)
+  - VGA resolution (640×480 @ 60fps)
+  - Can capture photos and videos
+- **Display**: 5-inch OLED touchscreen (original) or LCD (slim)
+- **CPU**: Quad-core ARM Cortex-A9 MPCore
+- **GPU**: Quad-core PowerVR SGX543MP4+
+- **RAM**: 512 MB system RAM, 128 MB VRAM
+
+### Project Fit Assessment
+✅ **Networking**: Yes - Wi-Fi built-in, suitable for Nextcloud uploads  
+✅ **Screenshots**: Yes - native system capability for game captures  
+✅ **Cameras**: Yes - can take photos with built-in cameras  
+✅ **Homebrew Scene**: Active community with VitaSDK  
+✅ **Container Support**: Official Docker images available  
+
+**Priority**: **HIGH** - Meets all requirements (networking + screenshots + cameras)
+
+---
+
+## VitaSDK Ecosystem
+
+### Official Resources
+- **Website**: https://vitasdk.org/
+- **GitHub Organization**: https://github.com/vitasdk (15 repositories)
+- **Docker Repository**: https://github.com/vitasdk/docker
+- **Package Repository**: https://github.com/vitasdk/packages (updated frequently)
+- **Samples Repository**: https://github.com/vitasdk/samples (335 stars)
+- **Documentation**: https://docs.vitasdk.org/
+
+### Toolchain Components
+- **vita-toolchain**: ARM-based cross-compiler (MIT license)
+- **newlib**: PS Vita port of C library (GPL-2.0)
+- **vita-headers**: System headers (233 stars, 94 forks)
+- **buildscripts**: CMake-based build system (65 stars)
+- **taihen**: Plugin framework
+- **libvita2d**: 2D graphics library
+
+### Package Management
+- **Tool**: vdpm (Vita SDK Package Manager)
+- **Type**: Shell-based installer scripts
+- **Repository**: https://github.com/vitasdk/packages
+- **Installation**: Bootstrap with `./install-all.sh` from vdpm repo
+- **Build Format**: vita-makepkg (similar to Arch Linux makepkg)
+
+### Build System
+- **Primary**: CMake with Vita-specific macros
+  - `vita_create_self()` - Creates SELF executable
+  - `vita_create_vpk()` - Creates VPK package
+- **Output Formats**:
+  - SELF: Signed ELF executable format
+  - VPK: Installable package archive (SELF + data + metadata)
+
+---
+
+## Official Docker Images
+
+### Available on Docker Hub
+```bash
+# Search results show multiple official images
+docker.io/vitasdk/vitasdk              # Main official image
+docker.io/vitasdk/vitasdk-softfp       # Soft float variant
+docker.io/vitasdk/buildscripts         # Build tools base image
+```
+
+### Base Image Structure
+From `github.com/vitasdk/docker`:
+
+**Main Dockerfile**:
+- Base: `vitasdk/buildscripts:latest`
+- Installs: git, curl, bash, make, pkgconf, cmake, sudo
+- Uses multi-stage build to clone and install vdpm
+- Installs all packages via `vdpm/install-all.sh`
+- Environment: `VITASDK=/usr/local/vitasdk`
+
+**Non-root Dockerfile**:
+- Same base, but creates unprivileged user
+- Adds sudo access for package installation
+- Better for local development (matches host UID)
+
+---
+
+## Container Strategy
+
+### Approach
+Unlike devkitPro platforms, VitaSDK already provides comprehensive official images with all packages pre-installed. Our strategy should be:
+
+**Option 1: Use Official Images Directly** (Recommended)
+- Use `vitasdk/vitasdk:latest` as-is
+- No custom Dockerfile needed
+- Pull official image when needed
+- Simplest approach, maintained by VitaSDK team
+
+**Option 2: Extend Official Images** (If customization needed)
+- Base: `FROM vitasdk/vitasdk:latest`
+- Add project-specific tools or scripts
+- Pin to specific tag for reproducibility
+- Only if we need additional packages
+
+### Tagging Strategy
+If we publish custom images:
+- Format: `tomusan/vitasdk-vita:<date>` or `tomusan/vitasdk-vita:<date>-v<semver>`
+- Example: `tomusan/vitasdk-vita:20251231` or `tomusan/vitasdk-vita:20251231-v1.0.0`
+- Follow same conventions as devkitPro containers
+
+---
+
+## Package Ecosystem Research
+
+### Known Libraries (from vdpm)
+- **zlib**: Compression library
+- **freetype**: Font rendering
+- **libvita2d**: 2D graphics library (Vita-specific)
+- **taihen**: Plugin framework (Vita-specific)
+
+### Additional Research Needed
+- [ ] Query vdpm package list for available networking libraries
+- [ ] Check for curl, libcurl support
+- [ ] Verify SSL/TLS libraries (mbedtls, openssl, etc.)
+- [ ] Check for image format libraries (PNG, JPEG)
+- [ ] Verify XML/JSON parsing libraries
+- [ ] Document complete package list similar to devkitPro research
+
+### How to Query Packages
+```bash
+# Run official container and list packages
+podman run --rm vitasdk/vitasdk:latest bash -c "cd /usr/local/vitasdk && find . -name '*.a' -o -name '*.so'"
+
+# Or check vdpm repository
+# Clone https://github.com/vitasdk/packages and inspect package definitions
+```
+
+---
+
+## Hardware Requirements
+
+### Hacked Console Required
+PS Vita homebrew requires modified firmware:
+- **HENkaku**: Firmware 3.60
+- **h-encore**: Firmware 3.65-3.68  
+- **Trinity**: Firmware 3.69-3.70
+
+This is similar to 3DS requiring custom firmware (CFW). Not a blocker for development, but users need hacked consoles to run homebrew.
+
+---
+
+## Implementation Plan
+
+### Phase 1: Research & Validation
+- [ ] Test official `vitasdk/vitasdk` image locally
+- [ ] Create simple "Hello World" program
+- [ ] Build VPK package and test on hardware/emulator
+- [ ] Document build process
+- [ ] Query complete package list from vdpm
+- [ ] Verify networking library availability (curl, SSL/TLS)
+
+### Phase 2: Integration Planning
+- [ ] Determine if custom Dockerfile is needed (likely not)
+- [ ] Create build scripts for Vita platform
+  - `scripts/build-vita.sh` - Build project using container
+  - `scripts/container-shell-vita.sh` - Interactive development shell
+- [ ] Update main `scripts/build-container.sh` to handle VitaSDK
+- [ ] Document Vita-specific build flags and configuration
+
+### Phase 3: Project Integration
+- [ ] Create Vita source directory structure
+- [ ] Implement Nextcloud client for Vita
+- [ ] Test screenshot upload functionality
+- [ ] Test camera photo upload functionality
+- [ ] Integrate with main project build system
+
+---
+
+## Platform Priority Assessment
+
+**Priority: HIGH**
+
+Justification:
+- ✅ Full networking support (Wi-Fi built-in)
+- ✅ Native screenshot capability for game captures
+- ✅ Dual cameras for photo capture
+- ✅ Active homebrew community and toolchain
+- ✅ Official Docker images available
+- ✅ Similar form factor to 3DS (handheld gaming device)
+- ✅ Fits project goals perfectly
+
+**Recommendation**: Add PS Vita alongside 3DS, Switch, and Wii U as HIGH priority platform.
+
+---

+
+# Interactive shell for development
+podman run --rm -it -v .:/project:z -w /project \
+  vitasdk/vitasdk:latest \
+  bash
+```
+
+### If Custom Image Needed
+```dockerfile
+# vita.Dockerfile
+FROM vitasdk/vitasdk:latest
+
+# Add any project-specific tools
+RUN apk add --no-cache \
+    vim \
+    tree \
+    htop
+
+# Set working directory
+WORKDIR /project
+```

+
+## Next Steps
+
+When ready to implement PS Vita support:
+
+1. **Test Official Image**:
+   ```bash
+   podman pull vitasdk/vitasdk:latest
+   podman run --rm -it vitasdk/vitasdk:latest bash
+   ```
+
+2. **Create Hello World**:
+   - Simple CMakeLists.txt
+   - Basic main.c with vita2d graphics
+   - Build VPK package
+
+3. **Research Networking Libraries**:
+   - Query vdpm for available packages
+   - Test curl/libcurl availability
+   - Verify SSL/TLS support
+
+4. **Determine Custom Dockerfile Need**:
+   - If official image has everything → use directly
+   - If missing tools → create custom Dockerfile extending official image
+
+5. **Update Main Plan**:
+   - Add PS Vita to DockerForDevkitARM.md platform summary
+   - Note it uses separate VitaSDK ecosystem
+   - Include in Phase 3 implementation alongside Wii U
+
+---
+
+## Notes
+
+- VitaSDK is completely independent from devkitPro - different organization, different toolchain
+- Official images already include most/all packages via vdpm install-all
+- May not need custom Dockerfile at all - official image might be sufficient
+- PS Vita was discontinued in 2019, but homebrew scene remains active
+- Estimated 15-16 million units sold worldwide (smaller than 3DS but larger than Wii U)
+- Active indie game development continues as of 2026

+  - Every commit on `main` is tagged with a version number
+  - Represents the current production state
+
+#### `develop` - Integration Branch
+- **Purpose**: Integration branch where features come together
+- **Rules**:
+  - Default branch for development
+  - Never commit directly to `develop`
+  - Receives merges from `feature/*` branches
+  - Always contains the latest delivered development changes
+  - Should always be in a working state
+
+#### `feature/*` - Feature Branches
+- **Purpose**: Develop new features or enhancements
+- **Naming**: `feature/<issue-number>-<short-description>`
+  - Example: `feature/8-webdav-client`
+- **Branch from**: `develop`
+- **Merge into**: `develop`
+- **Lifetime**: Deleted after merge
+
+**Creating a feature branch**:
+```bash
+git checkout develop
+git pull origin develop
+git checkout -b feature/8-webdav-client

+
+**Merging a feature**:
+```bash
+git checkout develop
+git merge --no-ff feature/8-webdav-client
+git push origin develop
+git branch -d feature/8-webdav-client
+```
+
+#### `release/*` - Release Preparation Branches
+- **Purpose**: Prepare for a new production release
+- **Naming**: `release/v<version>`
+  - Example: `release/v0.1.0`
+- **Branch from**: `develop`
+- **Merge into**: `main` AND `develop`
+- **Lifetime**: Deleted after merge
+
+**Creating a release branch**:
+```bash
+git checkout develop
+git checkout -b release/v0.1.0
+# Bump version numbers, update CHANGELOG, etc.
+```
+
+**Finishing a release**:
+```bash
+# Merge to main
+git checkout main
+git merge --no-ff release/v0.1.0
+git tag -a v0.1.0 -m "Release version 0.1.0"
+git push origin main --tags
+
+# Merge back to develop
+git checkout develop
+git merge --no-ff release/v0.1.0
+git push origin develop
+
+# Delete release branch
+git branch -d release/v0.1.0
+```
+
+#### `hotfix/*` - Emergency Fix Branches
+- **Purpose**: Quick fixes for critical production bugs
+- **Naming**: `hotfix/v<version>-<description>`
+  - Example: `hotfix/v0.1.1-fix-crash`
+- **Branch from**: `main`
+- **Merge into**: `main` AND `develop`
+- **Lifetime**: Deleted after merge
+
+**Creating a hotfix**:
+```bash
+git checkout main
+git checkout -b hotfix/v0.1.1-fix-crash
+# Make the fix
+```
+

+git merge --no-ff hotfix/v0.1.1-fix-crash
+git tag -a v0.1.1 -m "Hotfix version 0.1.1"
+git push origin main --tags
+
+# Merge to develop
+git checkout develop
+git merge --no-ff hotfix/v0.1.1-fix-crash
+git push origin develop
+
+# Delete hotfix branch
+git branch -d hotfix/v0.1.1-fix-crash
+```
+
+---
+
+## Development Setup
+
+### Prerequisites
+
+- **Podman** (preferred) or **Docker**
+- **Git**
+- **jq** (for config parsing)
+
+### Configuration
+
+1. **Copy the example config**:
+   ```bash
+   cp config.example.json config.json
+   ```
+
+2. **Edit `config.json`** with your Nextcloud test credentials:
+   ```json
+   {
+     "nextcloud": {
+       "url": "https://cloud.tomusan.com",
+       "username": "your-username",
+       "password": "your-app-password"
+     }
+   }
+   ```
+
+3. **Never commit `config.json`** - it's in `.gitignore`
+
+### Building with Containers

-### 2. Configure Test Environment
+### 2. Build the 3DS Development Container

-Copy the example configuration file:
+Build the container image (first time only, or when Dockerfile changes):
+
+```bash
+./scripts/build-container.sh 3ds
+```
+
+This creates a complete 3DS development environment with:
+- devkitARM GCC 15.2.0
+- All 47 available 3DS portlibs
+- CIA creation tools (bannertool, makerom, ctrtool)
+- Build time: ~10-15 minutes on first build
+
+**Note**: The container is built once and reused. You only rebuild when the Dockerfile changes.
+
+### 3. Compile Your 3DS Project
+
+```bash
+# From within your project directory
+cd your-3ds-project
+podman run --rm -v .:/project:z tomusan/devkitarm-3ds:latest make
+
+# Or specify a path
+podman run --rm -v ~/my-game:/project:z tomusan/devkitarm-3ds:latest make
+```
+
+**Output files**: `.3dsx` (homebrew), `.elf` (debug), `.smdh` (metadata), `.cia` (installable)
+
+### 4. Interactive Development Shell
+
+For debugging or manual builds:
+
+```bash
+# Current directory
+./scripts/container-shell.sh
+
+# Specific project
+./scripts/container-shell.sh ~/my-3ds-game
+
+# With extra volumes or environment
+./scripts/container-shell.sh ~/my-game -v /data:/data:z -e DEBUG=1
+```
+
+Inside the container, all devkitARM tools are available in PATH. Run `make` to build, `exit` to leave.
+
+### 5. Configure Test Environment (Optional)
+
+For testing with real Nextcloud servers, copy the example configuration:

 ```bash
 cp config.example config
@@ -79,40 +125,37 @@ NEXTCLOUD_USER=your-username
 NEXTCLOUD_PASSWORD=your-password
 ```

-**Note**: The `config` file is in `.gitignore` and will never be committed. Each developer should create their own local config.
-
-### 3. Build Using Podman
-
-#### Build the 3DS version:
-
-```bash
-# Build the container image (first time only)
-podman build -f docker/devkitarm.Dockerfile -t nextcloud-share-3ds .
-
-# Compile the project
-podman run --rm -v ./:/project:z nextcloud-share-3ds make -C 3ds
-
-# Output files will be in 3ds/build/
-```
-
-#### Run tests:
-
-```bash
-podman run --rm -v ./:/project:z nextcloud-share-3ds make test
-```
-
-#### Interactive development shell:
-
-```bash
-podman run --rm -it -v ./:/project:z nextcloud-share-3ds bash
-```
+**Note**: The `config` file is in `.gitignore` and will never be committed.

 ## 🔧 Building

-Detailed build instructions for each platform will be added as they are implemented. See platform-specific README files:
+### Using Development Containers

- [3ds/README.md](3ds/README.md) - Nintendo 3DS build instructions
- More coming soon...
+All builds run in isolated containers with complete toolchains. See [docker/README.md](docker/README.md) for detailed container documentation.
+
+**Available containers:**
+- **3DS**: `tomusan/devkitarm-3ds:latest` - Nintendo 3DS with full CIA support
+
+**Quick build commands:**
+```bash
+# Build 3DS container (first time)
+./scripts/build-container.sh 3ds
+
+# Compile a 3DS project
+podman run --rm -v ~/my-game:/project:z tomusan/devkitarm-3ds:latest make
+
+# Interactive shell
+./scripts/container-shell.sh ~/my-game
+```
+
+**Build performance:**
+- First build: ~10-15 minutes (downloads and compiles tools)
+- Subsequent builds: Instant (uses build cache)
+- Container rebuilds: Only needed when Dockerfile changes
+
+Platform-specific build instructions:
+- [docker/README.md](docker/README.md) - Container usage and CIA creation
+- More platforms coming soon...

+# Nintendo 3DS Development Container
+
+Complete Docker/Podman container for Nintendo 3DS homebrew development with full CIA file creation support.
+
+## Features
+
+- **Complete devkitARM toolchain** - GCC 15.2.0 for ARM development
+- **All 47 3DS portlibs** - Every available library including graphics, audio, networking, physics, and compression
+- **CIA Creation Tools**:
+  - `bannertool` - Creates banner and icon files for CIA packages
+  - `makerom` - Assembles final CIA installation files
+  - `ctrtool` - Inspects and validates CIA structure
+  - `3dstools` - Includes 3dsxtool, smdhtool, mkromfs3ds
+- **Build optimization** - ccache for faster rebuilds
+- **Modern build tools** - CMake, Ninja, Python 3
+
+## Quick Start
+
+### Using Helper Scripts (Recommended)
+
+The easiest way to use these containers is with the provided helper scripts:
+
+**1. Build the container:**
+```bash
+./scripts/build-container.sh 3ds
+```
+
+**2. Open interactive shell:**
+```bash
+# Current directory
+./scripts/container-shell.sh
+
+# Specific project
+./scripts/container-shell.sh ~/my-3ds-game
+
+# With additional volumes or environment
+./scripts/container-shell.sh ~/my-game -v /data:/data:z -e DEBUG=1
+```
+
+### Manual Container Usage
+
+If you prefer to use podman/docker commands directly:
+
+**Building the Container:**
+```bash
+# Using Podman (recommended for rootless operation)
+podman build -t tomusan/devkitarm-3ds:latest -f docker/3ds.Dockerfile .
+
+# Using Docker
+docker build -t tomusan/devkitarm-3ds:latest -f docker/3ds.Dockerfile .
+```
+
+Build time: ~10-15 minutes on first build (downloads and compiles bannertool, makerom, ctrtool)
+
+**Compiling a 3DS Project:**
+
+Basic compilation (produces .3dsx homebrew file):
+```bash
+podman run --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest make
+```
+
+With CIA file creation:
+```bash
+# Most 3DS projects with proper Makefile configuration
+podman run --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest make
+```
+
+Clean and rebuild:
+```bash
+podman run --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest bash -c "make clean && make"
+```
+
+**Interactive Shell:**
+
+For debugging or manual builds:
+```bash
+podman run -it --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest bash
+```
+
+## Helper Scripts
+
+### build-container.sh
+
+Builds and tags development containers with automatic runtime detection (podman/docker).
+
+**Usage:**
+```bash
+./scripts/build-container.sh <platform> [version]
+```
+
+**Examples:**
+```bash
+# Build with default version (0.1.0)
+./scripts/build-container.sh 3ds
+
+# Build with custom version
+./scripts/build-container.sh 3ds 0.2.0
+
+# Show help
+./scripts/build-container.sh --help
+```
+
+**Features:**
+- Auto-detects podman/docker runtime
+- Validates semantic versioning (X.Y.Z format)
+- Tags both version and latest
+- Colored output with build status
+- Shows usage examples after successful build
+
+**Environment Variables:**
+- `CONTAINER_RUNTIME` - Override runtime (podman or docker)
+
+### container-shell.sh
+
+Opens an interactive bash shell in the development container with your project mounted.
+
+**Usage:**
+```bash
+./scripts/container-shell.sh [project-path] [podman-args...]
+```
+
+**Examples:**
+```bash
+# Shell in current directory
+./scripts/container-shell.sh
+
+# Shell in specific project
+./scripts/container-shell.sh ~/my-3ds-game
+
+# With additional volume mount
+./scripts/container-shell.sh ~/my-game -v /data:/data:z
+
+# With environment variable
+./scripts/container-shell.sh ~/my-game -e DEBUG=1
+
+# Multiple extra arguments
+./scripts/container-shell.sh ~/my-game -v /data:/data:z -e DEBUG=1 --network=host
+```
+
+**Features:**
+- First argument = project path (defaults to current directory)
+- All additional arguments passed to podman/docker run
+- Auto-detects podman/docker runtime
+- Colored output with container information
+- Project mounted at `/project` with working directory set
+
+**Environment Variables:**
+- `CONTAINER_RUNTIME` - Override runtime (podman or docker)
+
+## Output Files
+
+A complete 3DS build produces:
+
+- **`.3dsx`** - Homebrew Launcher executable format
+- **`.elf`** - Executable with debug symbols
+- **`.smdh`** - Icon and metadata for Homebrew Launcher
+- **`banner.bnr`** - Banner displayed when CIA is selected on home menu
+- **`icon.icn`** - Icon file for CIA package
+- **`.cia`** - Installable file for 3DS home menu
+
+## CIA File Creation
+
+The container includes all tools needed for complete CIA file creation:
+
+### Manual CIA Creation Workflow
+
+If your Makefile doesn't include CIA generation:
+
+```bash
+podman run --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest bash -c '
+  # Build the application
+  make
+  
+  # Create banner (requires banner.png and audio.wav in assets/)
+  bannertool makebanner -i assets/banner.png -a assets/audio.wav -o build/banner.bnr
+  
+  # Create icon (requires icon.png in assets/)
+  bannertool makesmdh -s "App Title" -l "Description" -p "Author" \
+    -i assets/icon.png -o build/icon.icn
+  
+  # Create CIA file (requires app.rsf in assets/)
+  makerom -f cia -o output.cia -target t -exefslogo \
+    -elf output.elf -rsf assets/app.rsf \
+    -banner build/banner.bnr -icon build/icon.icn \
+    -DAPP_TITLE="App Title" \
+    -DAPP_PRODUCT_CODE="CTR-P-XXXX" \
+    -DAPP_UNIQUE_ID="0x12345"
+'
+```
+
+### Validating CIA Files
+
+```bash
+# Inspect CIA structure
+podman run --rm -v ./your-project:/project:z tomusan/devkitarm-3ds:latest \
+  ctrtool -i output.cia
+```
+
+## Installed Libraries
+
+The container includes all available 3DS portlibs:
+
+**Graphics & UI:**
+- citro3d, citro2d - 3DS GPU libraries
+- SDL, SDL_gfx, SDL_image, SDL_mixer, SDL_ttf
+- freetype, libpng, libjpeg-turbo, giflib
+
+**Audio:**
+- libopus, opusfile, libvorbisidec, libogg
+- flac, libmad, libmodplug, libxmp, mikmod, mpg123
+- wildmidi, libid3tag
+
+**Networking:**
+- curl, mbedtls, wslay
+
+**Data Formats:**
+- json-c, jansson, yaml_cpp, tinyxml2
+- libarchive, bzip2, liblzma, lz4, libzstd, zlib
+
+**Physics & Math:**
+- box2d, bulletphysics
+
+**Other:**
+- libconfig, libfribidi, libiconv, liblua51
+- physfs, libsidplay, libtheora
+
+## Container Environment
+
+```bash
+DEVKITPRO=/opt/devkitpro
+DEVKITARM=/opt/devkitpro/devkitARM
+PATH includes:
+  - ${DEVKITARM}/bin (ARM toolchain)
+  - /opt/devkitpro/tools/bin (bannertool, makerom, ctrtool)
+  - /usr/lib/ccache (build cache)
+```
+
+## Testing
+
+Verified working with:
+- **60/61 official 3ds-examples** - 98.4% success rate
+- **Checkpoint** - Real-world save manager application with full CIA creation
+
+## Troubleshooting
+
+### Permission Issues with Podman
+
+The `:z` flag in volume mounts sets proper SELinux context:
+```bash
+-v ./project:/project:z
+```
+
+### Container Size
+
+Expected size: ~1.6 GB (includes all libraries and build tools)
+
+### Build Cache
+
+To speed up rebuilds, the container uses ccache. The cache is stored in your project at `.ccache/`:
+```bash
+# Clean cache if needed
+rm -rf ./your-project/.ccache
+```
+
+### Common Errors
+
+**"makerom: command not found"**
+- Rebuild container with latest Dockerfile (includes makerom build steps)
+
+**"bannertool: command not found"**
+- Rebuild container with latest Dockerfile (includes bannertool build steps)
+
+**CIA creation fails silently**
+- Check that all required files exist:
+  - `assets/app.rsf` - CIA metadata
+  - `assets/banner.png` and `assets/audio.wav` - Banner resources
+  - `assets/icon.png` - Icon resource
+  - `output.elf` - Compiled application
+
+## Version Information
+
+- **Base Image**: devkitpro/devkitarm:20251231
+- **devkitARM**: GCC 15.2.0
+- **CMake**: 3.31.6
+- **GNU Make**: 4.3
+- **3DS Packages**: 47 portlibs installed
+
+## Building from Source
+
+The Dockerfile includes build steps for:
+
+1. **bannertool** (diasurgical/bannertool)
+   - Cloned with `--recursive` for submodules
+   - Built with system make
+   - Installed to `/opt/devkitpro/tools/bin/`
+
+2. **makerom & ctrtool** (3DSGuy/Project_CTR)
+   - Cloned from active fork
+   - Built dependencies first with `make deps`
+   - Built tools with `make`
+   - Installed to `/opt/devkitpro/tools/bin/`

+# Configuration Setup Guide
+
+This guide explains how to set up your Nextcloud configuration for development and testing.
+
+## Quick Start
+
+1. **Copy the example configuration**:
+   ```bash
+   cp config.example.json config.json
+   ```
+
+2. **Generate a Nextcloud App Password** (recommended for security):
+   - Go to your Nextcloud instance
+   - Navigate to: **Settings → Security → Devices & sessions**
+   - Scroll to "App passwords" section
+   - Enter a name (e.g., "nextcloud-share-dev")
+   - Click "Create new app password"
+   - Copy the generated token
+
+3. **Edit `config.json`** with your credentials:
+   ```json
+   {
+     "nextcloud": {
+       "url": "https://cloud.tomusan.com",
+       "username": "your-username",
+       "password": "xxxxx-xxxxx-xxxxx-xxxxx-xxxxx"
+     },
+     "settings": {
+       "maxRecentFolders": 5,
+       "uploadChunkSize": 10485760
+     }
+   }
+   ```
+
+4. **Validate your configuration**:
+   ```bash
+   ./scripts/validate-config.sh
+   ```
+
+## Generating App Passwords
+
+### For cloud.tomusan.com
+
+1. Log in to https://cloud.tomusan.com
+2. Click your profile icon (top right) → Settings
+3. Go to **Security** in the left sidebar
+4. Scroll down to **Devices & sessions**
+5. Under "App passwords" or "App-specific passwords":
+   - Enter a name: `nextcloud-share-dev`
+   - Click **Create new app password**
+6. Copy the generated password (format: `xxxxx-xxxxx-xxxxx-xxxxx-xxxxx`)
+7. Paste it into `config.json` as the `password` field
+
+### For disobedient.cloud/nextcloud
+
+1. Log in to https://disobedient.cloud/nextcloud
+2. Follow the same steps as above
+3. Generate a separate app password for this instance
+
+## Why App Passwords?
+
+App passwords are more secure than using your main account password because:
+
+- ✅ **Limited scope**: Only grants access to files, not account settings
+- ✅ **Revocable**: Can be revoked without changing your main password
+- ✅ **Traceable**: Shows up as a separate session in your account
+- ✅ **Safer storage**: If leaked, doesn't compromise your main account
+
+## Configuration Options
+
+### Required Fields
+
+- **`nextcloud.url`**: Your Nextcloud server URL (must use HTTPS in production)
+- **`nextcloud.username`**: Your Nextcloud username
+- **`nextcloud.password`**: App password or regular password
+
+### Optional Fields
+
+- **`settings.maxRecentFolders`**: Number of recent folders to remember (default: 5)
+- **`settings.uploadChunkSize`**: Upload chunk size in bytes (default: 10485760 = 10MB)
+
+## Environment Variable Overrides
+
+You can override any configuration value with environment variables (useful for CI/CD):
+
+```bash
+# Override config values
+export NEXTCLOUD_URL="https://cloud.example.com"
+export NEXTCLOUD_USER="testuser"
+export NEXTCLOUD_PASSWORD="app-password-here"
+
+# Run your tests
+./scripts/validate-config.sh
+```
+
+Environment variables always take precedence over `config.json`.
+
+## Loading Configuration
+
+To load configuration in your scripts:
+
+```bash
+#!/bin/bash
+source ./scripts/load-config.sh
+
+# Now you have access to:
+# - $NEXTCLOUD_URL
+# - $NEXTCLOUD_USER
+# - $NEXTCLOUD_PASSWORD
+# - $MAX_RECENT_FOLDERS
+# - $UPLOAD_CHUNK_SIZE
+```
+
+## Validating Configuration
+
+The validation script checks:
+
+- ✅ All required fields are present
+- ✅ URL format is valid
+- ✅ HTTPS is used (warns if HTTP)
+- ✅ Numeric settings are valid numbers
+
+```bash
+./scripts/validate-config.sh
+```
+
+## Security Notes
+
+- ⚠️ **Never commit `config.json`** - it's in `.gitignore`
+- ⚠️ **Use HTTPS**, not HTTP
+- ⚠️ **Use app passwords** when possible
+- ⚠️ **Revoke app passwords** when done with a project
+- ⚠️ Keep your `config.json` file permissions restricted:
+  ```bash
+  chmod 600 config.json
+  ```
+
+## Multiple Test Accounts
+
+If you have multiple Nextcloud instances for testing:
+
+**Option 1: Multiple config files**
+```bash
+cp config.example.json config-tomusan.json
+cp config.example.json config-disobedient.json
+
+# Use with:
+CONFIG_FILE=config-tomusan.json ./scripts/validate-config.sh
+```
+
+**Option 2: Environment variables**
+```bash
+export NEXTCLOUD_URL="https://disobedient.cloud/nextcloud"
+export NEXTCLOUD_USER="your-username"
+export NEXTCLOUD_PASSWORD="xxxxx-xxxxx-xxxxx-xxxxx-xxxxx"
+
+./scripts/validate-config.sh
+```
+
+## Troubleshooting
+
+### "jq is not installed"
+
+Install jq on your system:
+
+```bash
+# Ubuntu/Debian
+sudo apt-get install jq
+
+# macOS
+brew install jq
+
+# Arch Linux
+sudo pacman -S jq
+```
+
+### "NEXTCLOUD_URL must start with http:// or https://"
+
+Make sure your URL includes the protocol:
+- ✅ `https://cloud.tomusan.com`
+- ❌ `cloud.tomusan.com`
+
+### "Configuration is not valid"
+
+Run with the validation script to see specific errors:
+```bash
+./scripts/validate-config.sh
+```
+
+## CI/CD Configuration
+
+For Gitea Actions or other CI systems, set secrets in your repository:
+
+1. Go to repository **Settings → Secrets**
+2. Add these secrets:
+   - `NEXTCLOUD_TEST_URL`
+   - `NEXTCLOUD_TEST_USER`
+   - `NEXTCLOUD_TEST_PASSWORD`
+3. The CI will use environment variables instead of `config.json`
