-## Usage example
-
-### Step 1: Launch scheduler
-First launch our scheduler on the main node.
-```sh
-parallax run -m {model-name} -n {number-of-worker-nodes}
-```
-For example:
-```sh
-parallax run -m Qwen/Qwen3-0.6B -n 2
-```
-Please notice and record the scheduler ip4 address generated in the terminal.
-
-### Step 2: Join each distributed nodes
-For each distributed nodes including the main node, open a terminal and join the server with the scheduler address.
-```sh
-parallax join -s {scheduler-address}
-```
-For example:
-```sh
-# first node
-parallax join -s /ip4/192.168.1.1/tcp/5001/p2p/xxxxxxxxxxxx
-# second node
-parallax join -s /ip4/192.168.1.1/tcp/5001/p2p/xxxxxxxxxxxx
