+[on their doc site](https://docs.nova.app/syntax-reference/tree-sitter/#compiling-a-parser),
+and may be retrieved from
+[here](https://docs.nova.app/syntax-reference/build_script.zip).
+
+Run `build_parser.sh` (from project root) to build the
+`tree-sitter-svelte.dylib`:
+
+```sh
+./build_scripts/build_parser.sh /Applications/Nova.app
+```
+
+You may need to adjust the path to `Nova.app`. It will also copy the build
+output to correct place and cleanup temp files.
