How to use the server

Simply open your favourite web browser and go to https://, which will show the Element Web UI. Registrations are disabled by default.

Creating users

The first user will need to be created via command line interface, this is unique and it will be the admin user. To do this simply:

1. SSH into the host
2. Go to the directory /opt/matrix
3. Create the user running the following command:

% cd /opt/matrix
% docker compose exec synapse register_new_matrix_user --user <USER_NAME> --password <PASSWORD> --admin --config /data/homeserver.yaml

From there after, you can just use the admin panel to create users, the admin panel is located in https://<DOMIN>/admin (it requires admin user login)
