+# Notes on the overleaf implementation
+
+Local setup of overleaf:
+
+1. Download <https://github.com/overleaf/overleaf/blob/master/docker-compose.yml>.
+2. Adapt `volumes` (<https://github.com/overleaf/overleaf/blob/245fc120e6d50e8ee02d5900b8d6a8d6d8b9135c/docker-compose.yml#L20>).
+3. Execute `docker compose up`.
+4. Open <http://localhost/launchpad> to create the administrator user.
+5. Create the test user <jabref@example.org>.
+6. Copy the displayed password reset URL
+7. Open your browser in a private session.
+8. Go to the URL copied in step 6 and set the password `jabref`.
+9. Create a latex project with the example.
+
+After a successful setup, one can use <http://localhost> as "Server Address".
+
+After a session execute `docker compose down`
+
+More information on Overleaf is available at <https://github.com/overleaf/overleaf/wiki/Quick-Start-Guide>.
