+## Development
+
+The source language file is located at `src/typescript/Scala.tmlanguage.ts`. The output tmLanguage file `syntaxes/Scala.tmLanguage.json` is marked as ignored in git and shouldn't be commited.
+
+To generate the ouput file either use build command or run:
+
+```bash
+npm install
+npm build
+npx ts-node src/typescript/GenerateTmLanguageFile.ts > ./syntaxes/Scala.tmLanguage.json
+```
+
+The output file is validated against the json schema before being written.
