+### What is this?
+
+This is a mock OAuth server for testing purposes. It allows you to run pyroscope with oauth enabled locally by mimicking gitlab oauth server.
+
+
+### Usage
+
+To run the mock server, run the following command:
+```shell
+node ./scripts/oauth-mock/oauth-mock.js
+```
+
+To run pyroscope with the right config run:
+```shell
+make build
+bin/pyroscope server -config scripts/oauth-mock/pyroscope-config.yml
+```
+
+Then go to http://localhost:4040/ and pyroscope should send you to log in via GitLab (which is really just our mock in this case).
