Server configuration

Jet lets you configure some aspects of the server, which are implemented by default. You will learn how to do that from this guide.

Initial configuration guide

Configuration of the server can be done by editing a server.yaml text file, whose defauls are generated on a first server startup.

To change a specific field, you replace a text it follows. Reading this guide or comments before a field can help with knowing what the text should be replaced with.

This section contains guides of changing specific configuration fields.
