There is a sort|uniq command that I use for awesome-baremetal, can you run that over this text? It may mean we lose the extra space between bullet points.

We could add this into the file at the end of the list, so it can be run easily and prevent this happening again

Done. Multiple use cases are mentioned for few adopters. So we may have to be compare output before updating the list.
