 ## About ##
 Scribd-dl helps downloading documents on [scribd.com](https://www.scribd.com/) and [slideshare.net](https://www.slideshare.net/) without membership / sign-in.  
 
-## Development Plan ##
-Scribd obfuscates the .pdf files, the texts copied from the documents might become strange garbled message.  
-De-obfuscating will be the next stage of this project.
-

+To use Scridb-dl, you need to install [Node.js](https://nodejs.org/en/download/). It is recommended that you use the latest LTS version available.  
+
+> Please install Node.js using pre-built installers for your platform. You may encounter incompatibility issues with different development tools otherwise.  
+
+To check that Node.js was installed correctly, type the following commands in your terminal client:  
+```console
