+# Release Tracker
+
+A Zig application that monitors releases from starred repositories across GitHub, GitLab, Codeberg, and SourceHut, generating an RSS feed for easy consumption.
+
+Needs to be able to rotate PAT on GitLab
+
+## Features
+
+- Monitor releases from multiple Git hosting platforms
+- Generate RSS feed of new releases
+- Configurable authentication for each platform
+- Designed to run periodically as a CLI tool
+- Static file output suitable for deployment on Cloudflare Pages
+
+## Building
+
+Requires Zig 0.14.1:
+
+```bash
+zig build
+```
+
+## Usage
+
+1. Copy `config.example.json` to `config.json` and fill in your API tokens
+2. Run the application:
+
+```bash
+./zig-out/bin/release-tracker config.json
+```
+
+3. The RSS feed will be generated as `releases.xml`
+
+## Configuration
+
+Create a `config.json` file with your API tokens:
+
+```json
+{
+  "github_token": "your_github_token",
+  "gitlab_token": "your_gitlab_token", 
+  "codeberg_token": "your_codeberg_token",
+  "sourcehut": {
+    "repositories": [
+      "~sircmpwn/aerc",
+      "~emersion/gamja"
+    ]
+  },
+  "last_check": null
+}
+```
+
+### API Token Setup
+
+- **GitHub**: Create a Personal Access Token with `public_repo` and `user` scopes
+- **GitLab**: Create a Personal Access Token with `read_api` scope
+- **Codeberg**: Create an Access Token in your account settings
+- **SourceHut**: No token required for public repositories. Specify repositories to track in the configuration.
+
+## Testing
+
+Run the test suite:
+
+```bash
+zig build test
+```
+
+## Deployment
+
+This tool is designed to be run periodically (e.g., via cron) and commit the generated RSS file to a Git repository that can be deployed via Cloudflare Pages or similar static hosting services.
+
+Example cron job (runs every hour):
+```bash
+0 * * * * cd /path/to/release-tracker && ./zig-out/bin/release-tracker config.json && git add releases.xml && git commit -m "Update releases" && git push
+```
