 When converting a Prism CSS theme it's mostly just necessary to use classes as
 `types` and convert the declarations to object-style-syntax and put them on `style`.
 
+### Providing a CSS based theme
+
+In order to use a CSS based theme like the ones from [PrismJS](/~https://github.com/PrismJS/prism-themes), you need to disable the built in theme.

+## Development
+
+Local development setup can be run with the following commands running Node 18.x. This project uses corepack to specify its package manager version and you should have it enabled locally using `corepack enable`.
+
+```
+$ pnpm install
+$ pnpm build
+$ pnpm test
+```
+
+### Local Demo
+
+To run the local demo, ensure you have first run `pnpm build`, then run `pnpm start:demo` and open the provided URL to the demo site in your terminal.
+
+```
+$ pnpm build
+$ pnpm start:demo
+```
+
+The workspace projects are linked, so changes can be hot reloaded during development by running multiple terminals
+
+```
+// terminal 1
+$ pnpm build:watch
+```
+
+```
+// terminal 2
+$ pnpm start:demo
+```
