 ## Update guide
 
+### You can use the update.sh script to update your apache2/src/ directory by doing the following (thanks to @Kevin-Mizu):   
+(don't forget to change the path in your command)   
+```
+wget https://raw.githubusercontent.com/Ooggle/dead-simple-blog/master/update.sh
+chmod u+x ./update.sh
+./update.sh path/to/apache2/src/
+```
+
 In order to update the website to the latest version, you need to download the latest release, copy the content of the new `src/apache2/src/` in your own `apache2/src/` directory.
 
 :warning: If you don't want all your work to be lost, don't copy:
