 ## Installing
 
@@ -12,34 +12,17 @@ Install `ascii-shot` with `npm`
 npm install ascii-shot -g
 ```
 
-## Usage (CLI)
+## Usage
 
-### ascii-shot
-Prints your latest Instagram shot as an ASCII version to `stdout`.
-
-``` bash
-ascii-shot
 ```
+  Usage
+    $ ascii-shot <username>
 
-## Setting up
-Instagram API is quite restrictive, so you'll need to jump through some hoops.
-
-1. Setup your client here: https://www.instagram.com/developer/
-2. Set your `INSTAGRAM_CLIENT_ID`, `INSTAGRAM_CLIENT_SECRET` and `INSTAGRAM_REDIRECT_URI` as environment variables. For example
-
-``` bash
-  set INSTAGRAM_CLIENT_SECRET=your_secret_here
+  Examples
+    $ ascii-shot petetnt
 ```
 
-When you run `ascii-shot`, it will automatically fetch your `access_token` and show your newest Instagram shot. If it's your first time running the script, it will most likely ask you to authoritize the app.
-
-After you have successfully gained your `access_token`, check the console and save it as an environment variable `INSTAGRAM_ACCESS_TOKEN` to skip further need to get it again. (The tokens, however, might expire at some point so you might need to get another later).
-
-## Why would I want this?
-¯\\\_(ツ)_/¯
-
-Like I said, the API is quite restrictive and this is pretty much all ASCII fun you can have without breaking all or some of the rules.
-
+And then use spacebar to fetch more images. Any other key will exit the program.
