-### Goals of This Repository
-
-The intention with this repository is to create a place which tracks
-all the documentation changes across the 'Personal Flash in Real-Time'
-project in one place. This should help people whom are not exposed to
-the project in any sustained way have a single place they can go to
-for information about the projects within 'Personal Flash in
-Real-Time'. With that said, **the documentation hosted here is for
-technicians and 'back of house' staff**. The content within this
-repository does not prioritise general public use.
-
-You can read the documentation in this repository in two ways:
-
-1. read the raw markdown (.md) files within the project folders in
-  this repository, or;
-2. ~~download a 'Released' version and read that (as a .pdf).~~
