 ## Some tips
 
 - If you create a tenant using the interactive console (`artisan tinker`) and use sqlite, you might need to change the database's permissions and/or ownership (`chmod`/`chown`) so that the web application can access it.
+
+## HTTPS certificates
+
+HTTPS certificates are very easy to deal with if you use the `yourclient1.yourapp.com`, `yourclient2.yourapp.com` model. You can use a wildcard HTTPS certificate.
+
+If you use the model where second level domains are used, there are multiple ways you can solve this.
+
+This guide focuses on nginx.
+
+### 1. Use nginx with the lua module
+
+Specifically, you're interested in the [`ssl_certificate_by_lua_block`](https://github.com/openresty/lua-nginx-module#ssl_certificate_by_lua_block) directive. Nginx doesn't support using variables such as the hostname in the `ssl_certificate` directive, which is why the lua module is needed.
+
+This approach lets you use one server block for all tenants.
+
+### 2. Add a simple server block for each tenant
+
+You can store most of your config in a file, such as `/etc/nginx/includes/tenant`, and include this file into tenant server blocks.
+
+```nginx
+server {
+  include includes/tenant;
+  server_name foo.bar;
+  # ssl_certificate /etc/foo/...;
+}
+```
+
+### Generating certificates
+
+You can generate a certificate using certbot. If you use the `--nginx` flag, you will need to run certbot as root. If you use the `--webroot` flag, you only need the user that runs it to have write access to the webroot directory (or perhaps webroot/.well-known is enough) and some certbot files (you can specify these using --work-dir, --config-dir and --logs-dir).
+
+Creating this config dynamically from PHP is not easy, but is probably feasible. Giving `www-data` write access to `/etc/nginx/sites-available/tenants.conf` should work.
+
+However, you still need to reload nginx configuration to apply the changes to configuration. This is problematic and I'm not sure if there is a simple and secure way to do this from PHP.
+
+## Testing
+
+If you run the tests of this package, please make sure you don't store anything in Redis @ 127.0.0.1:6379 db#14. The contents of this database are flushed everytime the tests are run.
