### Adding a server to the list

Mindustry now has a public list of servers that everyone can see and connect to. 
This is done by letting clients `GET` a [JSON list of servers](https://github.com/Anuken/Mindustry/blob/master/servers_v6.json) in this repository.

You may want to add your server to this list. The steps for getting this done are as follows:

0. **Take note of the fact that modded servers are not allowed on this list.** Such servers confuse users, and there's currently no easy way to fix mod incompatibilities after a failed connection.
1. **Ensure your server is properly moderated.** For the most part, this applies to survival servers, but PvP servers can be affected as well.
You'll need to either hire some moderators, or make use of (currently non-existent) anti-grief and anti-curse plugins.
*Consider enabling a rate limit:* `config messageRateLimit 2` will make it so that players can only send messages every 2 seconds, for example.
2. Make sure that your server is able to handle inappropriate content - this includes NSFW display/sorter art and abusive messages. **Servers that allow such content will be removed immediately.** Consider banning display blocks if it is a problem for your server: `rules add bannedBlocks ["canvas", "logic-display", "large-logic-display"]`.
3. **Set an appropriate MOTD, name and description.** This is set with `config <name/desc/motd> <value>`. "Appropriate" means that:
   - Your name or description must reflect the type of server you're hosting. 
   Since new players may be exposed to the server list early on, put in a phrase like "Co-op survival" or "PvP" so players know what they're getting into. Yes, this is also displayed in the server mode info text, but having extra info in the name doesn't hurt.
   - Make sure players know where to refer to for server support. It should be fairly clear that the server owner is not me, but you.
   - Try to be professional in your text; use common sense.
4. **Get some good maps.** *(optional, but highly recommended)*. Add some maps to your server and set the map rotation to custom-only. You can get maps from the Steam workshop by subscribing and exporting them; using the `#maps` channel on Discord is also an option.
5. **Check your server configuration.** *(optional)* I would recommend adding a message rate limit of 1 second (`config messageRateLimit 1`), and disabling connect/disconnect messages to reduce spam (`config showConnectMessages false`).
6. Finally, **submit a pull request** to add your server's IP to the list. 
This should be fairly straightforward: Press the edit button on the [server file](https://github.com/Anuken/Mindustry/blob/master/servers_v6.json), then add a JSON object with a single key, indicating your server address.
For example, if your server address is `example.com:6000`, you would add a comma after the last entry and insert:
    ```json
      {
        "address": "example.com:6000"
      }
    ```
    > Note that Mindustry also support SRV records. This allows you to use a subdomain for your server address instead of specifying the port. For example, if you want to use `play.example.com` instead of `example.com:6000`, in the dns settings of your domain, add an SRV record with `_mindustry` as the service, `tcp` as the protocol, `play` as the target and `6000` as the port. You can also setup fallback servers by modifing the weight or priority of the record.

    Then, press the *'submit pull request'* button and I'll take a look at your server. If I have any issues with it, I'll let you know in the PR comments.
