-1. Lookup specific data from CourtListener:
-
-        docker exec -it bc2-django python manage.py lookup 64983976

-1. Create mastodon subscription to push notifications:
-
-        docker exec -it bc2-django python manage.py mastodon-subscribe
-
-    This command requires that the following variables are set in the .env file: `MASTODON_SHARED_KEY`, `MASTODON_PUBLIC_KEY`, `MASTODON_PRIVATE_KEY`and `HOSTNAME`. We added a script to generate the first three variables. Execute the following command to use the script and paste the result in your .env file:
-
-        docker exec -it bc2-django python /opt/bigcases2/scripts/get-mastodon-keys.py
