-* Splitting / checking postgresql
-* Setting up element-web + config
-* Defining the homeserver.yaml
-* Integration with certbot

-## Next
-
-* create db.yaml with

-#  name: psycopg2
-#  args:
-#    user: synapse_user

-#    cp_min: 5
-#    cp_max: 10

-* create log.config
-* put pvc at /media_store

 ## Components
 
-### General
-
-* Need switches for element-web (?)
-  * Or always deploy
-
 ### element-web
 
 * Needs config: /app/config.json

-* Requires homeserver.yaml for starting
-* Need to overwrite the entrypoint
-* How/where do we specifiy the postgresql password?
-  * Maybe in our own init container using alpine?

 ## Missing
 
-- db secret generation (sops?)
-  - done via mittwald
 - SMTP settings / secrets (ungleich mail + sops?)
-- Exposing sizes in value.yaml (db, gitea)
-  - Maybe reducing to 1 PVC?

-## TODOs
-
-- Move postgres into own service -> stays running by default
-
-## Reset
-
-What I want:
-
-- Easy access to latest matrix version
-  - Based on the official container makes sense
-- Being able to inject postgres secret
-- Postgres not restarting if synapse is getting updated
-  - 2nd service could nicely solve that
