-as follows:
-
- * The relevant libraries are included in the Docker images and Debian packages
-   provided by `matrix.org` so no further action is needed.
-
- * If you installed Synapse into a virtualenv, run `/path/to/env/bin/pip
-   install synapse[pyjwt]` to install the necessary dependencies.
-
- * For other installation mechanisms, see the documentation provided by the

 ## How to test JWT as a developer
 
 Although JSON Web Tokens are typically generated from an external server, the
