-BFO-9000
-========
-
-A split full-size ortholinear keyboard made and sold by Keebio. Each half is a 6x9 arrangement, with breakable pieces to allow the number of rows to be customized between 4 to 6, and the number of columns to be between 7 to 9. [More info at Keebio](https://keeb.io).
-
-Keyboard Maintainer: [Bakingpy/nooges](https://github.com/nooges)
-Hardware Supported: Pro Micro
-Hardware Availability: [Keebio](https://keeb.io)
-
-Make example for this keyboard (after setting up your build environment):
-
- make bfo9000:default
-
-Example of flashing this keyboard:
-
- make bfo9000:default:avrdude
-
-See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
