 Note that MeshCentral does not currently support placing a Let’s Encrypt certificate in the database. Generally, one would use a reverse proxy with Let’s Encrypt support and TLS offload in the reverse proxy and then run MeshCentral in state-less mode in a Docket container.
 
+## Commandline Options
+
+In general, doing `--option value` is the same as adding `"option": value` in the settings section of the config.json.
+
+Here are the most common options found by running `meshcentral --help`

 ## TLS Offloading
 
 A good way for MeshCentral to handle a high traffic is to setup a TLS offload device at front of the server that takes care of doing all the TLS negotiation and encryption so that the server could offload this. There are many vendors who offer TLS or SSL offload as a software module (Nginx* or Apache*) so please contact your network administrator for the best solution that suits your setup.
