+As I already said it's a terminal based application, so you have to run it from linux terminal. Let's start-
+
+1. First of all, let's download the binary application using the following command line:
+
+```
+wget https://github.com/imShakil/PCiNooB/raw/master/PCiNooB
+```
+2. Give permission to run this file:
+
+```
+chmod +x PCiNooB
+```
 
+3. Finally, run the application as below:
 
+```
+./PCiNooB
+```
+
+That's all. It will run and save some hardware information to a external txt file.
