Why should this be gitignored?
If it's okay, let's checkin the default .env file, it will be easier for others to run the code my making minimal edits.

It shouldn't be a problem right now. But since we also store secrets as env variables, I just added it to gitignore. Also, I think generally most projects keep
.envin.gitignore.There was a problem hiding this comment.

I think it would be better to store these values as constants inside a go file instead of committing the
.envfile to git.
