+## Contributing

+### Running Playground CLI from source
+
+To set it up:
+
+```bash
+# If you don't have the repository cloned yet:
+git clone -b trunk --single-branch --depth 1 --recurse-submodules https://github.com/WordPress/wordpress-playground.git
+cd wordpress-playground
+
+# Alternatively, if you already have a clone but forgot to
+# pull the submodules, you can run:
+cd wordpress-playground
+git submodule update --init --recursive
+
+nvm use 23
+npm install
+```
+
+To run it:
+
+```bash
+node --experimental-strip-types --experimental-transform-types --import ./packages/meta/src/node-es-module-loader/register.mts ./packages/playground/cli/src/cli.ts
+```
+
+Or this instead of the above:
+
+```bash
+nx dev playground-cli server
+```
+
+### How can I contribute?
