-## Post-receive hook (auto-update on push)
-
-To regenerate the site automatically on each push, create a
-[post-receive](https://git-scm.com/docs/git-receive-pack#_post_receive_hook)
-hook in your bare repository:
-
-```sh
-#!/bin/sh
-gitmal --git --output /var/www/html/repo /path/to/repo.git
-```
-
-```sh
-chmod +x hooks/post-receive
-```
-
-Now every `git push` triggers a fresh build, and clients can clone immediately via HTTP.
-
-## Private read-write access
-
-Keep the SSH protocol for private write access:
-
-```sh
-git remote add origin git@example.com:repo.git
-git push origin main
-git clone http://example.com/repo   # public, read-only
-```
