-
+```
+git clone https://github.com/Ylianst/MeshCentral.git
+cd MeshCentral/docker
 docker build -t meshcentral .
+```
+
+docker-compose.yml example:
+```yaml
+version: '2'
+services:
+    meshcentral:
+        restart: always
+        container_name: meshcentral
+        image: meshcentral
+        ports:
+            - 8086:443  #MeshCentral will moan and try everything not to use port 80, but you can also use it if you so desire, just change the config.json according to your needs
+        environment:
+            - HOSTNAME=my.domain.com     #your hostname
+            - REVERSE_PROXY=false     #set to your reverse proxy IP if you want to put meshcentral behind a reverse proxy
+            - REVERSE_PROXY_TLS_PORT=
+            - IFRAME=false    #set to true if you wish to enable iframe support
+            - ALLOW_NEW_ACCOUNTS=true    #set to false if you want disable self-service creation of new accounts besides the first (admin)
+            - WEBRTC=false  #set to true to enable WebRTC - per documentation it is not officially released with meshcentral, but is solid enough to work with. Use with caution
+        volumes:
+            - ./meshcentral/data:/opt/meshcentral/meshcentral-data    #config.json and other important files live here. A must for data persistence
+            - ./meshcentral/user_files:/opt/meshcentral/meshcentral-files    #where file uploads for users live
