added release script and docs

 You can also make use of snapshot feature of the virtualization software to easily revert to a clean state after testing, 
 e.g. state directly after Linux Mint installation, before running the post-installation script. 
 This way you can test the script multiple times without needing to reinstall Linux Mint each time.

+## Release Process
+
+This project uses a simple release process based on git tags.
+
+### Versioning
+- Version is stored in `VERSION` file (format: v0, v1, v2, ...)
+- Major version increments only (major-bugfix scheme)
+- Script version is also stored in `SCRIPT_VERSION` variable within the main script to display version during script execution
+
+### Creating a Release
+Run the release script from the repository root:
+```bash
+./release.sh
+```
+
+The script will:
+1. Check for uncommitted local changes (exits if any exist)
+2. Show current version and propose next version
+3. Prompt for confirmation
+4. Update VERSION file and SCRIPT_VERSION in the script
+5. Create a git commit
+6. Create an annotated tag
+7. Prompt to push to origin (including tags)
+
+### Gitea Integration
+When a tag is pushed to the remote, Gitea automatically creates a release from it.
+
+### Requirements
+- Clean working tree (no uncommitted changes)
+- Git remote configured (origin)
