 ## Key Files to Understand
 1. `CountryTags.sp` - Main plugin logic
-2. `sourceknight.yaml` - Build dependencies and configuration
+2. `.github/workflows/ci.yml` - Build dependencies, configuration, and release automation
 3. `countryflags.cfg` - Country to flag ID mappings
-4. `.github/workflows/ci.yml` - Build and release automation
 
 When working on this plugin, prioritize stability and performance since it affects all players on a server. Always test changes thoroughly and consider the impact on server performance.
