 You can check out a proof of concept in the `examples/haproxy-sni` folder,
 and especially have a look at [this section of the haproxy.cfg](https://codeberg.org/Codeberg/pages-server/src/branch/main/examples/haproxy-sni/haproxy.cfg#L38).

+If you want to test a change, you can open a PR and ask for the label `build_pr_image` to be added.
+This will trigger a build of the PR which will build a docker image to be used for testing.

 ### Environment Variables

 - `ACME_ACCEPT_TERMS` (default: use self-signed certificate): Set this to "true" to accept the Terms of Service of your ACME provider.
- `ACME_API` (default: <https://acme-v02.api.letsencrypt.org/directory>): set
-  this to <https://acme.mock.director> to use invalid certificates without any
-  verification (great for debugging). 
-ZeroSSL might be better in the future as it doesn't have rate limits and doesn't clash with the official Codeberg certificates (which are using Let's Encrypt), but I couldn't get it to work yet.

 - `ACME_EAB_KID` & `ACME_EAB_HMAC` (default: don't use EAB): EAB credentials, for example for ZeroSSL.
 - `ACME_EMAIL` (default: `noreply@example.email`): Set the email sent to the ACME API server to receive, for example, renewal reminders.
 - `ACME_USE_RATE_LIMITS` (default: true): Set this to false to disable rate limits, e.g. with ZeroSSL.
- `DNS_PROVIDER` (default: use self-signed certificate): Code of the ACME DNS
-  provider for the main domain wildcard. 
-See <https://go-acme.github.io/lego/dns/> for available values & additional environment variables.
+- `DNS_PROVIDER` (default: use self-signed certificate): Code of the ACME DNS provider for the main domain wildcard. See <https://go-acme.github.io/lego/dns/> for available values & additional environment variables.
 - `ENABLE_HTTP_SERVER` (default: false): Set this to true to enable the HTTP-01 challenge and redirect all other HTTP requests to HTTPS. Currently only works with port 80.
 - `GITEA_API_TOKEN` (default: empty): API token for the Gitea instance to access non-public (e.g. limited) repos.
 - `GITEA_ROOT` (default: `https://codeberg.org`): root of the upstream Gitea instance.
