+Matrix Stack bestehend aus Matrix Server "Synapse" sowie dem Frontend "Element".
+
+## Inital setup
+1. Copy env file: `cp env.sample .env`
+2. Edit env file: `nano .env`
+   1. Basedir: Full path to dir with compose file (important for swarm shares)
+   2. Versionnumbers
+   3. DB settings
+   4. Domain! (no default)
+2. Genreate inital config for synapse:
+   1. `source .env`
+   2. `docker run -it --rm -v --env-file .env ${BASEDIR:-.}/files/:/data -e SYNAPSE_SERVER_NAME=$DOMAIN -e SYNAPSE_REPORT_STATS=no matrixdotorg/synapse:latest generate`
+        - This generate certs and basic inital config (homeserver.yml) for $DOMAIN only for first setup needed
+
+Postgress by default not in use!  
+Default DB is SQLite.
+
+3. (optional) Set db in config: `nano $BASEDIR/files/synapse/homeserver.yaml`
+4. Edit element config: `nano files/element-config.json`
+   1. set "default_server_name" to your domain for Synapse
+   2. set "m.homeserver" => "base_url" to your domain for Element
+   3. Hint: by default connection to main servers of matrix.org is enabled
+   4. Hint: by default jitsi (cloud!) is uses for **group** videocalls 
+      - > [^jitsi]: 1:1 calls, or calls between you and one other person, do not use Jitsi. Instead, those calls work directly between clients or via TURN servers configured on the respective homeservers.
+      - Hint: Jisi can be selfhost (no templace exist atm)
+
+5. Run stack `docker compose up`
+
+## howto
+
+### enable registration
+1. edit `homeserver.yaml`
+   1. set "enable_registration" to "True"
+   2. set "enable_registration_without_verification" to "True" # note: maybe not comming soon..
+
+For disable ... well you know, set "enable_registration" to "False" 
+
+### create user via cli
+1. Import .env or set $DOMAIN manually
+2. Set env $USERNAME and $USERPASS oder replace it directly
+```
+source .env
+docker exec -it matrix_app_1 register_new_matrix_user -u $USERNAME -p $USERPASS -a -c /data/homeserver.yaml $DOMAIN
+```
+
+## todo
+- setup script to auto edits
+  -  db in homeserver.yml 
+  -  domain in config.json (element)
