Step missing in install doc? #69

. . .

Following doc here for recommended docker install :
https://www.[librechat.ai/docs/local/docker](https://www.librechat.ai/docs/local/docker)

Git installed no problem, as did repository clone, change directory no worries, but step 3, namely

"cp .env.example .env"

Returned an error:

"cp: cannot stat '.env.example': No such file or directory"

Tried copy too, but nah ... am guessing? There is a missing command to akshully create the file or directory first, before the cp or copy (Windows) command. Probably obvious for tech inclined, but confusing for non-experts like me.
