+```
+
+## Setup
+
+### 1. Clone Configuration
+
+```bash
+git clone https://git.digitevents.com/ai/opencode.git ~/.config/opencode
+```
+
+### 2. Configure Environment Variables
+
+Create `env.sh` file (not tracked in git) or use the one from iCloud:
+
+```bash
+# Option 1: Create manually
+cat > ~/.config/opencode/env.sh << 'EOF'
+# OpenCode Environment Variables
+export REF_API_KEY="your-ref-api-key"
+export FIGMA_API_KEY="your-figma-api-key"
+export GITEA_API_TOKEN="your-gitea-token"
+EOF
+
+# Option 2: Use iCloud (macOS only)
+# File location: ~/Library/Mobile Documents/com~apple~CloudDocs/opencode-env.sh
+```
+
+### 3. Load Environment Variables
+
+Add to your `~/.zshrc` or `~/.bashrc`:
+
+```bash
+# Load from iCloud (macOS)
+[[ -f ~/Library/Mobile\ Documents/com~apple~CloudDocs/opencode-env.sh ]] && \
+  source ~/Library/Mobile\ Documents/com~apple~CloudDocs/opencode-env.sh
+
+# Or load from local file
+[[ -f ~/.config/opencode/env.sh ]] && source ~/.config/opencode/env.sh
+```
+
+Then reload your shell:
+```bash
+source ~/.zshrc
+```
+
+## Usage
+
+### Commands
+
+Run custom commands in OpenCode TUI:
+
+- `/auto-commit` - Auto-generate commit and create tag
+- `/commit-push` - Commit, tag and push to remote
+- `/create-gitea-repo` - Create repository on Gitea
+- `/sync-oc-pull` - Pull OpenCode config changes
+- `/sync-oc-push` - Push OpenCode config changes
+- `/review` - Review code or documentation
+
+### Skills
+
+Skills are automatically loaded by agents when needed:
+
+- `android-developer` - Android development with Kotlin/Compose
+- `electron-developer` - Electron desktop app development
+- `ios-developer` - iOS development with Swift/SwiftUI
+- `go-developer` - Go backend development
+
+### MCP Services
+
+Configure MCP services in `opencode.json`:
+
+- `ref` - Ref.tools API (requires `REF_API_KEY`)
+- `figma` - Figma Developer MCP (requires `FIGMA_API_KEY`)
+
+## Sync Across Devices
+
+### Push Changes
+
+```bash
+cd ~/.config/opencode
+git add .
+git commit -m "chore: update config"
+git push
+```
+
+### Pull Changes
+
+```bash
+cd ~/.config/opencode
+git pull
+```
+
+Or use the built-in commands:
+- `/sync-oc-push` - Push changes
+- `/sync-oc-pull` - Pull changes
+
+## Security
+
+**Important**: Never commit sensitive information like API keys to git.
+
+- `env.sh` is ignored by git
+- Store credentials in iCloud or use a secure password manager
+- Use environment variables instead of hardcoding secrets
