Thank you for creating this repo. I've gone through both ansible and docker from lemmy's official documentation and without your scripts I would have given up on lemmy!

It may be obvious, but it may be helpful to some users if README also included a cron job to keep the deployment up to date? Even something simple like:

crontab -e

# every day at 4:21am
21 4 * * * cd ~/Lemmy-Easy-Deploy && git pull origin main && git checkout $(git describe --tags `git rev-list --tags --max-count=1`) && ./deploy.sh

Thank you for your suggestion! However due to Lemmy's history of having a few mishaps during previous version bumps, and because I may ask the user questions in this script, I'm not comfortable recommending completely hands-off upgrades with no user confirmation.

However, you're welcome to continue doing this for your server, and I'll try to keep this in mind when working on the CLI!
