-## Bemerkungen
-
-- die `.ocis/config/ocis.yaml` wird erzeugt auf Grundlage der `.env`
-- wenn man sich plötzlich nicht mehr über OIDC anmelden kann, kann das daran lieget, dass `.ocis/idm/ldap.crt` abgelaufen ist — siehe dazu [diesen Thread](https://central.owncloud.org/t/certificate-error-after-upgrade-to-5-0-0-from-4-0-6/47824/7); man könnte auch `OCIS_LDAP_INSECURE` auf `true` setzen, aber naja…
-
-
 ## ToDo
 
 - Download prüfen
-- `csp.yaml` einsetzen
-- prüfen ob folgende `.env`-Variablen gebraucht werden:
-  - `PROXY_OIDC_ISSUER`
-  - `PROXY_OIDC_SKIP_USER_INFO`
