You can declare an unlimited number of servers, however you must provide valid values for the fields listed above. In addition to that, the server can declare modules.
Only one server in the array should have the `default_selected` property enabled. This will tell the launcher that this is the default server to select if either the previously selected server is invalid, or there is no previously selected server. This field is not defined by any server (avoid this), the first server will be selected as the default. If multiple servers have `default_selected` enabled, the first one the launcher finds will be the effective value. Servers which are not the default may omit this property rather than explicitly setting it to false.
## Modules

Other times, you may want to store the files maven-style, such as with libraries and mods. In this case you must declare the module as the example artifact above. The `id` becomes more important as it will be used to resolve the final path. The `id` must be provided in maven format, that is `group.id.maybemore:artifact:version`. From there, you need to declare the `extension` of the file in the artifact object. This effectively replaces the `path` option we used above.
**It is EXTREMELY IMPORTANT that the file size is CORRECT. The launcher's download queue will not function properly otherwise.**
