Document how to generate a key

I confirm that #2 works

Thanks!

Automatically closed - issue fixed for 2 weeks with no activity.

It would be nice to specify in the instructions that the command is for a 256-bit key, especially since 128-bit is the default setting when creating a key

I created 📌 Create new stable release for 8.x-2.6 Active which would get these instructions in a stable release.
