 # Yaml Pipelines for Sublime Text
 
-Syntax highlighting definitions for YAML pipeline files, like GitHub Actions and AzureDevops.
+Syntax highlighting definitions for YAML pipeline files, like GitHub Actions and AzureDevops, Drone CI, GitLab CICD etc.
 Includes a small plugin to automatically apply the GitHub Actions filetype when loading or saving a YAML file in a `.github/workflows` folder.
 
 Why not just use the default YAML syntax definition? Because it doesn't highlight conditions, variables or embedded Bash or PowerShell scripts!
