 ### Steps to follow after adding a new example

-  script:
-    - npm run test:external -- -- -- https://github.com/ipfs-examples/{TODO_GIT_URL}.git

+#### Update `js-ipfs` to run tests against the repo
+
+Open a PR to the [ipfs/js-ipfs](https://github.com/ipfs/js-ipfs) project that edits the `.github/workflows/test.yml` in order to make sure a js-ipfs release does not break your new example.
+
+Search `.github/workflows/test.yml` for the `test-examples` section and add a block at the end of the `example` matrix key similar to:
+
+```yml
+- name: my super fun new example
+  repo: https://github.com/ipfs-examples/js-ipfs-my-super-fun-new-example.git
+  deps: ipfs-core@$PWD/packages/ipfs-core/dist,ipfs-http-client@$PWD/packages/ipfs-http-client/dist
+```
+
+The value of the `deps` key will vary depending on which modules from js-ipfs your example uses. Above we override the `ipfs-core` and `ipfs-http-client` modules, but your example may different deps.
+
+Please see the existing setup in `.github/workflows/test.yml` for how to ensure you are overriding the correct modules.
