+## Installation
+
+### Download from GitHub Releases
+
+You can download the latest pre-built binary for your platform from the [GitHub Releases page](https://github.com/gitpod-io/prometheus-decoder/releases).
+
+### Build from Source
+
+```bash
+git clone https://github.com/gitpod-io/prometheus-decoder.git
+cd prometheus-decoder
+go build
+```
+
+## Development
+
+This project uses GitHub Actions to automatically build and publish releases when a new tag is pushed to the repository.
+
+### Creating a New Release
+
+1. Update the version number in `main.go`
+2. Commit your changes
+3. Tag the commit with a version number:
+   ```bash
+   git tag v0.1.0
+   git push origin v0.1.0
+   ```
+4. GitHub Actions will automatically build binaries for multiple platforms and create a new release
+
