Getting started is easy. If you don't have it already, install NodeJS. Then, create an empty folder and do this:

 npm install meshcentral
 node node_modules/meshcentral

That's it. MeshCentral will set itself up and start managing computers on your local network. By default it will be setup in LAN mode and agents you install will multicast on the local network to find the server. To setup the server so that agents use a well known DNS name and to start customizing your server, go in the "meshcentral-data" folder and edit the config.json file. The configuration file must be valid JSON, you can use this link to validate the file format.
