 With Gogs' ability to authenticate over SMTP it is trivial to integrate it with mailcow. Few changes are needed:
 
-1\. Open `docker-compose.yml` and add Gogs:
+1\. Open `docker-compose.override.yml` and add Gogs:
 
 ```
+version: '2.1'
+services:
+
     gogs-mailcow:
       image: gogs/gogs
       volumes:
         - ./data/gogs:/data
       networks:
         mailcow-network:
-          ipv4_address: 172.22.1.123
           aliases:
             - gogs
       ports:
-        - "${GOGS_SSH_PORT:-50022}:22"
-        - "${GOGS_WWW_PORT:-50080}:3000"
-      dns:
-        - 172.22.1.254
-
+        - "${GOGS_SSH_PORT:-127.0.0.1:4000}:22"
 ```
 
-2\. Open `data/conf/nginx/site.conf` and add in each `server{}` block
+2\. Create `data/conf/nginx/site.gogs.custom`, add:
 ```
 location /gogs/ {
-    proxy_pass http://172.22.1.123:3000/;
+    proxy_pass http://gogs:3000/;
 }
 ```
 
-3\. Open `mailcow.conf` and define ports you want Gogs to open, as well as future database password. Example:
+3\. Open `mailcow.conf` and define the binding you want Gogs to use for SSH. Example:
 
 ```
-GOGS_WWW_PORT=3000
-GOGS_SSH_PORT=4000
-DBGOGS=CorrectHorseBatteryStaple
+GOGS_SSH_PORT=127.0.0.1:4000
 ```
 
-4\. Create database and user for Gogs to use.
+5\. Run `docker-compose up -d` to bring up the Gogs container and run `docker-compose restart nginx-mailcow` afterwards.
 
-```
-. ./mailcow.conf
-docker-compose exec mysql-mailcow mysql -uroot -p$DBROOT
-mysql> CREATE USER gogs IDENTIFIED BY 'CorrectHorseBatteryStaple';
-mysql> CREATE DATABASE gogs;
-mysql> GRANT ALL PRIVILEGES ON gogs.* to gogs;
-```
+6\. Open `http://${MAILCOW_HOSTNAME}/gogs/`, for example `http://mx.example.org/gogs/`. For database details set `mysql` as database host. Use the value of DBNAME found in mailcow.conf as database name, DBUSER as database user and DBPASS as database password.
 
-5\. Run `docker-compose up -d` to bring up Gogs container. Verify with `curl http://172.22.1.123:3000/` that it is running.
+7\. Once the installation is complete, login as admin and set "settings" -> "authorization" -> "enable SMTP". SMTP Host should be `postfix` with port `587`, set `Skip TLS Verify` as we are using an unlisted SAN ("postfix" is most likely not part of your certificate).
 
-6\. Proceed to installer from browser, for the time being using direct url `http://${MAILCOW_HOSTNAME}:${GOGS_WWW_PORT}/`, for example `http://example.org:3000/`. For database details set `mysql` as database host, user `gogs`, database name `gogs` and password as set above
-
-7\. Once install is complete, login as admin and in settings - authorization enable SMTP. SMTP Host should be `172.22.1.8` with port `587`. You'll probably want to set `Skip TLS Verify`.
-
-8\. Edit `data/gogs/gogs/conf/app.ini` and set following values. You can consult [Gogs cheat sheet](https://gogs.io/docs/advanced/configuration_cheat_sheet) for their meaning and other possible values.

 [server]
 SSH_LISTEN_PORT = 22
-SSH_DOMAIN = [domain where ssh is available - used for ssh clone url]
-SSH_PORT = [port where ssh is open on host - used for ssh clone url]
-ROOT_URL = https://[url]/gogs/
+# For GOGS_SSH_PORT=127.0.0.1:4000 in mailcow.conf, set:
+SSH_DOMAIN = 127.0.0.1
+SSH_PORT = 4000
+# For MAILCOW_HOSTNAME=mx.example.org in mailcow.conf (and default ports for HTTPS), set:
+ROOT_URL = https://mx.example.org/gogs/
 ```
 
 9\. Restart Gogs with `docker-compose restart gogs-mailcow`. Your users should be able to login with mailcow managed accounts.
