 ### Create a short link
 If you want that Shorty creates a short link for you, you have to send
 him a PUT request. The following example will show you how it works with
-curl from a mac.
+curl in the terminal.
 
 ```
 curl -X PUT -H 'Authorization: 5449f071773861dca4d3b459aa79fcf5' -d 'https://github.com/patrick-blom/shorty' http://127.0.0.1:8000

 If he finds a result he will pass a 301 HTTP Response including the 
 original url back to the browser. 
 
+### Delete a short link
+Sometimes it happens that you pass something to Shorty you want to delete 
+later. This can happen for several reasons. One reason could be that there is a typo
+in your very long url and you don't want to mess up the database. Another one 
+could be, that you only want to share the short link for a limited amount of time.
+Never mind, there can always be a reason for the deletion of a short link. So if
+you want to delete a short link you have to send Shorty a DELETE request with the
+created short code. If we take the example from above, it would look like this.
+
+```
+curl -X DELETE -H 'Authorization: 5449f071773861dca4d3b459aa79fcf5' -d '950a0065' http://127.0.0.1:8000

+-d '950a0065': The short code which was created by Shorty during the PUT request
+http://127.0.0.1:8000: Your running Shorty

+
+If everything works as expected, Shorty will return a 410 HTTP Gone Response. 
+Otherwise you will end up with an 400 HTTP Bad Request Response.
+
+### Security
+Shorty's defense is really simple. The only thing between the world and the database
+are your authorization tokens. So please keep the following recommendations in mind
+
+- choose long and complex tokens
+- never share your tokens 
+- never use the same token for PUT and DELETE 
+- always use HTTPS, if you can

 ## Testing
 If you want to test Shorty you can this by simply run a regular
 `composer install` and `composer test` in the project root. This will
