 > Attention ! The nyn project is archived and it is recommended to use the c language version of zzz instead of it ! In order to commemorate nyn, the name of this project is not modified.
 
+## How to use
+
+- Step 0: Make sure you have an ``openwrt router``, ``download the ipk`` in Releases in this project, and ``upload and install`` it in the system-package of the Luci background.
+- Step 1：Fill in the user name: Student ID@operator. For example, ``212306666@cucc``, China Unicom is cucc, mobile is cmcc, and telecom is ctcc.
+- Step 2: Fill in the password. The ``initial password`` is the last six digits of the ID card by default. It can be modified in the official client.
+- Step 3: Select your network card; generally speaking, you can use ``ip addr`` to view the network card that has been assigned an IP, such as eth1.
+- Step 4: ``Start the service`` and observe whether you can access the Internet, and then enable ``scheduled startup``; because the campus network will be closed from 12:00 to 7:00 the next day.
+- Finally，enjoy it!

 - You can use this command to find the compiled ipk:
 
 ```
