-*Without Guns* allows you to quickly turn ON and OFF the following widely used Visual Studio Code features:
+*Without Guns* allows you to quickly turn ON and OFF the following Visual Studio Code features:
 - IntelliSense
 - Syntax Highlighting
 - Code Lens
 
 When these features are turned OFF, we say that we code "without guns".
 
 Occasional coding without guns forces you to code mindfully and yields the following benefits:
-- Increased coding confidence
-- Deeper knowledge of programming language syntax and features
-- Deeper knowledge of used frameworks and libraries
+- **Increased coding confidence**
+- **Deeper knowledge of programming language syntax and features**
+- **Deeper knowledge of used frameworks and libraries**
 
 I suggest coding without guns whenever you learn something new, being that a new programming language, algorithm, framework or a technology.
 
+## Usage
+To start coding without guns simply call the `Guns: Without` command from the Command Palette. To get the guns back, call the `Guns: With` command. An image is worth a thousand words, therefore:

 ## FAQ
 ### Q: Why is the extension called "Without Guns"? Do you like guns?
 No, I don't like guns. On the contrary, I dream of a world without them. The origin of the name is a story of its own :-) It has something to do with a quote from the 1996 film [Last Man Standing](https://en.wikipedia.org/wiki/Last_Man_Standing_(1996_film)) starring [Karina Lombard](https://en.wikipedia.org/wiki/Karina_Lombard), [Bruce Willis](https://en.wikipedia.org/wiki/Bruce_Willis), and [Christopher Walken](https://en.wikipedia.org/wiki/Christopher_Walken). I plan to write a blog post about it. The blog post will also explain the whole philosophy behind the programming without guns.
