 ## Running a node
 
-A node needs to connect to some network, either local one (usually referred to

-is stored in a file and NeoGo allows you to store multiple files in one

-To start Neo node on a private network, use:
+### Initial Setup
 
+First, generate the configuration files for all available networks:
+
+```bash
+./bin/neo-go config generate --all
 ```
+
+This command will create configuration files for each network in 
+the `./config` directory. You need to run this step only once before the first run.
+
+### Starting the Node
+
+To start a Neo node on a private network, use:

 ./bin/neo-go node
