currently Edrys requires a mail to be send, delivered and read within 30 seconds (and 1 to 30 seconds of the generation period) this increases that period to 5 minutes (and the 1 to 30 seconds of the current)

30 seconds are a bit optimistic

The server might start, but somehow docker will not recognize localhost and thus the port will not be exposed. 0.0.0.0 has to be used instead of localhost.

Just added some notes about the steps, which are required to deploy edrys to heroko ...

SMTP settings are not included ...

Maybe the sub-folder of docs can be used to provide detailed descriptions for different platforms.

SMTP-client will not provide a connection for more than a few minutes. After a certain period it disconnects and a new send request will result in a crash of the system.

For simplicity I had updated the dockerfile, so that all content is loaded into the edrys folder instead of root. This allows also to define a volume within the docker-compose.yml such that content within /edrys/.edrys will be preserved ...

Maybe the edrys publish-subscibe module could be used as an connector/provider for Yjs? This way, it would be possible to make use of all collaborative projects (also for the monaco-editor) ...
