+$ cd tmp
+```
+
+### Copy to 
+
+If your operating system is Ubuntu16.04, and you install nginx with `sudo apt-get install nginx` directly (maybe you should run `sudo apt-get update && apt-get upgrade nginx` first), run
+
+```cmd
+$ sudo mkdir /usr/share/nginx/modules
+$ cp ./ubuntu_x86_64/nginx-xenial-1.10.3/ngx_pagespeed.so /usr/share/nginx/modules/
+```
+
+
+If you install nginx with `sudo add-apt-repository ppa:nginx/stable && apt-get update && apt-get install nginx` (maybe you should run `sudo apt-get update && apt-get upgrade nginx` first), run
+
+```cmd
+$ sudo mkdir /usr/share/nginx/modules
+$ cp ./ubuntu_x86_64/nginx-stable-1.12.1/ngx_pagespeed.so /usr/share/nginx/modules/
+```
+
+
+### Load Module
+
+edit `/etc/nginx/nginx.conf`, e.g.
+
+```conf
+user www-data;
+worker_processes auto;
+pid /run/nginx.pid;
+
+load_module modules/ngx_pagespeed.so;
+
+events {
+        worker_connections 768;
+        # multi_accept on;
+}
+
+http {
+    ...
+}
+```
+

+### Test 
+
+run `sudo nginx -t`, if you get output as follow, that means it works

+nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
+nginx: configuration file /etc/nginx/nginx.conf test is successful
+```
