If you want to use Forgejo with SSH and be able to pull/push with your SSH key, your SSH daemon must be properly configured to use private/public keys. Here is a sample configuration `/etc/ssh/sshd_config` that works with Forgejo:
Actually it's possible to access to the Git repositories by the `git` command over HTTP also in private mode installation. It's important to know that in this mode the repository could be ALSO getted if you don't set the repository as private in the repos settings.
By default, NGINX is configured with a maximum value for uploading files at 200 MB. It's possible to change this value on `/etc/nginx/conf.d/my.domain.tld.d/forgejo.conf`.
