 The sower is a cross-platform intelligent transparent proxy tool. It provide both socks5 proxy and DNS-based proxy. All these kinds of proxy support intelligent router.
 
 If you already have another proxy solution, you can use it's socks5(h) service as a parent proxy to enjoy the sower's intelligent router.

 ## Installation

 To enjoy the sower, you need to deploy sower on both server-side(sowerd) and client-side(sower).

+_If you wanna use sower as secondary proxy to provide intelligent router, you can skip sowerd._
 
 At the server-side, the sowerd runs just like a web server proxy. It will occupy two ports `80` / `443`.
 
 You can use your own certificate or the certificate automatically applied for by the sowerd from [`Let's Encrypt`](https://letsencrypt.org/).
 
 There are two ways to run the sowerd service:
+
 1. run the shell command with root permission
-    ``` shell
-    # sowerd -password XXX -fake_site 127.0.0.1:8080
-    ```
+
+   ```shell
+   # sowerd -password XXX -fake_site 127.0.0.1:8080
+   ```
+
 2. install as a systemd service
-    ```service
-    [Unit]
-    Description=sower server service
