 The objective of this project is for you to create a simple [shell](https://en.wikipedia.org/wiki/Unix_shell).
 
-Through the `0-shell` you will get to the core of the `Unix` system and explore an important part of this system’s API witch is the process creation and synchronization.

-Executing a command inside a shell implies creating a new process, which execution and final state will be monitored by its parents process. This set of functions will be the key to success for your project.

 ### Instructions
 
 - You must program a mini `Unix shell`, try to focus on something simple like [BusyBox](https://en.wikipedia.org/wiki/BusyBox).
-- This interpreter must display at least a simple `$` and wait until you type a command line witch will be validated by pressing enter.
+- This interpreter must display at least a simple `$` and wait until you type a command line which will be validated by pressing enter.
 - The `$` will be shown again only once the command has been completely executed.
 - The command lines are simple, you will not have pipes, redirection or any other advanced functions.
 - You must manage the errors, by displaying a message adapted to the error output.
