+# Readme.md
+
+In `readme.md` we should explain that `npm install` can be used both with and without development dependencies.
+
+We are likely to want some development dependencies for the following purposes:
+
+- Template processing
+- Ecmascript parsing for inline rich semantic documentation
+
+
+## Installing tree-sitter-javascript
+
+- requires `node-gyp`
+
+```sh
+CXXFLAGS="-std=c++20" npm i -D tree-sitter tree-sitter-javascript
+```
+
