 ## Naming Your Keyboard/Project
 
-All keyboard names are in lower case, consisting only of letters, numbers, and underscore (`_`). Names may not begin with an underscore. The names `test`, `keyboard`, and `all` are reserved for make commands and may not be used as a keyboard or subfolder name.

 ## Image/Hardware Files
 
-In an effort to keep the repo size down, we're no longer accepting images of any format in the repo, with few exceptions. Hosting them elsewhere (imgur) and linking them in the `readme.md` is the preferred method.

 Any sort of hardware file (plate, case, pcb) can't be stored in qmk_firmware, but we have the [qmk.fm repo](https://github.com/qmk/qmk.fm) where such files (as well as in-depth info) can be stored and viewed on [qmk.fm](http://qmk.fm). Downloadable files are stored in `/<keyboard>/` (name follows the same format as above) which are served at `http://qmk.fm/<keyboard>/`, and pages are generated from `/_pages/<keyboard>/` which are served at the same location (.md files are generated into .html files through Jekyll). Check out the `lets_split` directory for an example.
