+# Freedom Loader - Development Guide
+
+Welcome to the Developer Guide! This document explains how to set up your local environment, project architecture, Git workflow, and the release process.
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed on your machine:
+
+- **Node.js** (v22 or higher recommended)
+- **npm** (comes with Node.js)
+- **Git**
+- **yt-dlp binaries**: Freedom Loader requires native binaries to function. Read [BINARIES.md](./BINARIES.md) for download instructions and placement in `resources/binaries/`.
+
+## Setup Instructions
+
+### 1. Clone the repository
+
+```bash
+git clone https://github.com/MasterAcnolo/Freedom-Loader.git
+cd Freedom-Loader
+```
+
+### 2. Install dependencies
+
+```bash
+npm install
+```
+
+### 3. Install the Binaries
+
+Follow the instructions in `BINARIES.md` to place `yt-dlp`, `ffmpeg`, `ffprobe`, and `deno` in the correct `resources/binaries/` folder for your OS.
+
+### 4. Run in Development Mode
+
+```bash
+npm start
+```
+
+**Note**: Development mode automatically enables detailed colored logs and the DevTron extension for debugging.
+
+---
+
+## Available Scripts
+
+### Development
+
+- `npm start` — Start the app in development mode (no warnings)
+- `npm run start:warn` — Start with deprecation warnings visible
+- `npm run start:debug` — Start with full debug logging (Wayland, Electron logging, stack dumps)
+- `npm run dev` — Start with auto-reload on file changes (watches server/, app/, main.js, config.js)
+- `npm run dev:warn` — Dev mode with warnings
+- `npm run dev:debug` — Dev mode with full debug output and auto-reload
+
+### Building
+
+- `npm run build:linux` — Build Linux packages (AppImage, deb, snap)
+- `npm run build:win` — Build Windows installer (.exe)
+- `npm run build:rpm` — Build RPM and SRPM for COPR (Fedora)
+- `npm run build:all` — Build both Windows and Linux (not recommended because it adds both OS binaries into a single package. The output file is 2x bigger than expected).
+
+### Testing
+
+- `npm test` — Run all tests (unit + integration)
+- `npm run test:unit` — Run unit tests only
+
+### Release Pipeline
+
+- `npm run release` — Build all packages and create a draft GitHub release (no store publishing)
+- `npm run release:publish` — Build all packages and publish to Snap Store + COPR
+- `npm run release:dry-run` — Simulate the full release pipeline without publishing anything
+
+### Maintenance
+
+- `npm update` — Update npm dependencies
+
+---
+
+## Project Architecture
+
+Freedom Loader is built with **Electron** (frontend) and **Node.js + Express** (backend), using a modular structure:
+
+---
+
+## Git & Branching Workflow
+
+I use **Trunk-Based Development** (GitHub Flow):
+
+### Core Principles
+
+- **`main` is always deployable**: The `main` branch contains the latest stable code and must never be broken.
+- **No long-lived branches**: I no longer maintain version branches like `v1.6` or `v1.7`.
+- **Pull Requests for review**: All code changes go through PR review before merging to `main`.
+
+### How to Contribute
+
+#### 1. Create a feature branch
+
+```bash
+git checkout -b feat/add-new-button
+# or for fixes:
+git checkout -b fix/ui-bug
+```
+
+**Branch naming convention**:
+- `feat/` — New features
+- `fix/` — Bug fixes
+- `refactor/` — Code cleanup (no behavior change)
+- `docs/` — Documentation updates
+- `chore/` — Dependency updates, build config, etc.
+
+#### 2. Make commits
+
+```bash
+# Make changes
+git add .
+git commit -m "Brief, imperative description of the change"
+```
+
+**Commit message tips**:
+- Use imperative mood: "Add theme caching" not "Added theme caching"
+- Keep commits logical and focused (one feature per commit if possible)
+- Link to issues if relevant: "Fix crash on download (fixes #42)"
+
+#### 3. Push and open a PR
+
+```bash
+git push origin feat/add-new-button
+```
+
+Then open a PR on GitHub against `main`.
+
+#### 4. Review and merge
+
+- Address feedback in new commits (don't rebase — easier to review)
+- Once approved, merge via GitHub (use "Squash and merge" for clean history if many small commits and you find it relevant)
+
+---
+
+## Release Process
+
+**Note**: Only project maintainers release to production. This section documents the process for transparency and for future maintainers.
+
+Releases are fully automated via the `release.sh` script. The process handles building, packaging, and publishing to **all distribution channels**:
+- **GitHub Releases** (Windows .exe, Linux packages)
+- **Fedora COPR** (automatic RPM builds for Fedora 43+)
+- **Snap Store** (universal Linux)
+
+### Before You Release
+
+1. **Ensure `main` is green**: All tests pass, features are stable.
+2. **Update `package.json` version**:
+
+```json
+   "version": "1.6.1"
+```
+3. **Commit the version bump**: `git add package.json && git commit -m "chore: v1.6.1"`
+4. **Push to `main`**: `git push origin main`
+
+### Step 1: Local Build & Draft Release
+
+```bash
+npm run release
+```
+
+This:
+1. Builds Linux packages (AppImage, deb, snap)
+2. Builds RPM and SRPM for COPR
+3. Builds Windows installer
+4. Creates a draft GitHub release
+
+### Step 2: Edit & Publish on GitHub
+
+1. Go to https://github.com/MasterAcnolo/Freedom-Loader/releases
+2. Edit the draft release — fill in changelog
+3. Click **"Publish"** to make it live
+
+### Step 3: Publish to Distribution Channels
+
+```bash
+npm run release:publish
+```
+
+This automatically:
+- **Uploads to Snap Store**: Makes the app available via `snap install freedom-loader`
+- **Submits to Fedora COPR**: Builds and publishes RPMs for Fedora 43+ (users can `dnf install freedom-loader` from the COPR repo)
+
+Both happen in parallel — users across all platforms get the release simultaneously.
+
+---
+
+## Linux Development Considerations
+
+### Cross-Distribution Compatibility
+
+Freedom Loader targets **Debian-based** (Ubuntu, Debian) and **Fedora-based** (Fedora, RHEL, openSUSE) distributions. When developing features, keep this in mind:
+
+#### What to test
+
+- **Feature works on Fedora 44+** (primary Linux development environment)
+- **Feature works on Ubuntu/Debian** (via deb package or AppImage)
+- **Feature doesn't break Snap confinement** (Snap has restricted filesystem/IPC access)
+- **Feature gracefully degrades on missing system dependencies**
+
+#### Desktop Environment (DE) Compatibility
+
+Test on at least **GNOME** and **KDE** (the most common DEs). Common pain points:
+
+- **Themes**: May render differently on KDE vs GNOME — test both if possible
+- **File dialogs**: Some DEs use native file pickers, others fall back to Electron's
+- **Notifications**: System notification APIs vary (D-Bus, libnotify)
+- **Tray icons**: May not work identically across DEs
+
+#### How to check locally
+
+```bash
+# Test on Fedora (if available)
+npm run build:linux
+sudo dnf install dist/freedom-loader-*.x86_64.rpm
+freedom-loader
+
+# Test AppImage (works on any distro)
+chmod +x dist/Freedom\ Loader-*.AppImage
+./dist/Freedom\ Loader-*.AppImage
+```
+
+### CI/CD Gap
+
+**Currently**: No automated testing across distros or DEs. Releases rely on manual testing before publish.
+
+**Future improvement**: Automated tests via GitHub Actions (Ubuntu) + local testing on Fedora would catch cross-distro issues early. This is planned but not yet implemented.
+
+For now, if you fix a Linux-specific bug or add a DE-dependent feature, **please mention it in your PR description** so reviewers can test extra carefully.
+
+---
+
+## Testing
+
+### Unit Tests
+
+Test individual functions in isolation (no Electron required).
+
+```bash
+npm run test:unit
+```
+
+Covered:
+
+(Tests will come soon)
+
+### End-to-End Tests (Playwright)
+
+Test the actual Electron app launching and basic UI interactions.
+
+```bash
+npm run test
+```
+
+Covered:
+
+(Tests will come soon)
+
+
+### Running All Tests
+
+```bash
+npm test
+```
+
+Or include tests before release:
+
+```bash
+npm test && npm run release
+```
+
+---
+
+## Common Tasks
+
+### Add a new feature
+
+1. Create a feature branch: `git checkout -b feat/my-feature`
+2. Make changes, commit: `git add . && git commit -m "feat: my feature"`
+3. Push: `git push origin feat/my-feature`
+4. Open a PR on GitHub
+5. Once approved, merge to `main`
+6. (Later) Cut a release when ready: `npm run release`
+
+### Fix a bug
+
+Same as above, but use `fix/bug-name` branch and `git commit -m "fix: description"`.
+
+### Test the app before releasing
+
+```bash
+npm run dev        # Auto-reload on file changes
+# Make changes, test in the UI
+npm test           # Run all tests
+npm run release:dry-run   # Simulate release (builds but doesn't publish)
+```
+
+### Update dependencies
+
+```bash
+npm update
+git add package.json package-lock.json
+git commit -m "chore: update dependencies"
+git push origin main
+```
+
+### Rebuild only Linux (after quick fixes)
+
+```bash
+npm run build:linux
+# Or just the RPM:
+npm run build:rpm
+```
+
+### Publish to stores manually
+
+If `npm run release:publish` fails partway:
+
+```bash
+# Just Snap:
+snapcraft upload dist/freedom-loader_*.snap --release=stable
+
+# Just COPR:
+copr-cli build freedom-loader srpm-out/*.src.rpm
+```
+
+---
+
+## Troubleshooting
+
+### App won't start in dev mode
+
+```bash
+npm run start:debug
+```
+
+Check the debug output for errors. Most common:
+- Missing binaries in `resources/binaries/`
+- Port 8787 already in use
+- A dead instance is still running — open Task Manager and kill the "Freedom Loader" process
+
+### (Linux) Binaries in the right place but app still won't launch
+
+You probably forgot to make them executable:
+
+```bash
+chmod +x resources/binaries/linux/*
+```
+
+The app will fail silently if binaries lack execute permissions.
+
+### Build fails with "permission denied"
+
+Make sure you have write access to `dist/` and `srpm-out/`:
+
+```bash
+chmod -R u+w dist srpm-out
+npm run build:linux
+```
+
+### Tests fail
+
+Check for:
+- Missing test files in `tests/unit/`
+- Node modules out of sync: `rm -rf node_modules && npm install`
+
+### GitHub release publish fails
+
+Verify `gh` CLI is installed and authenticated:
+
+```bash
+gh auth login
+gh release list
+```
