 ## Development info
 
-Running the tests requires Musixmatch credentials. The credentials are read
-from the `MUSIXMATCH_EMAIL` and `MUSIXMATCH_PASSWORD` environment variables.
+You can choose which client to test by setting the `MUSIXMATCH_CLIENT` environment
+variable to either `Desktop` or `Android` (it defaults to Desktop).
 
-To make local development easier, I have included `dotenvy` to read the
-credentials from an `.env` file. Copy the `.env.example` file
-in the root directory, rename it to `.env` and fill in your credentials.
