 ## Adding New Sites
 
 Please look at the Wiki entry on
-[adding new sites](https://github.com/TheYahya/sherlock/wiki/Adding-Sites-To-Sherlock)
+[adding new sites](https://github.com/sherlock-project/sherlock/wiki/Adding-Sites-To-Sherlock)
 to understand the issues.
 
 Any new sites that are added need to have a username that has been claimed, and one
 that is unclaimed documented in the site data.  This allows the regression tests
 to ensure that everything is working.
 
+It is required that a contributer test any new sites by either running the full tests, or running
+a site-specific query against the claimed and unclaimed usernames.
+
+It is not required that a contributer run the 
+[site_list.py](https://github.com/sherlock-project/sherlock/blob/master/site_list.py)
+script.
+
+If there are performance problems with a site (e.g. slow to repond, unrealiable uptime, ...), then
+the site may be removed from the list.

 In regards to adult sites (e.g. PornHub), we have agreed to not include them in Sherlock.  
 However, we do understand that some users desires this support.  The data.json file is easy to add to, 
 so users will be able to maintain their own forks to have this support. This is not ideal.
