If your keyboard has been advertised to be powered by QMK but is not in the list, chances are a developer hasn't gotten to it yet or we haven't had a chance to merge it in yet. File an issue at [qmk_firmware](https://github.com/qmk/qmk_firmware/issues) requesting to support that particular keyboard, if there is no active [Pull Request](https://github.com/qmk/qmk_firmware/pulls?q=is%3Aopen+is%3Apr+label%3Akeyboard) for it. There are also QMK powered keyboards that are in their manufacturer's own GitHub accounts. Double check for that as well. <!-- FIXME(skullydazed): This feels too wordy and I'm not sure we want to encourage these kinds of issues. Also, should we prompt them to bug the manufacutrer? -->
Choose the layout that best represents the keymap you want to create. Some keyboards do not have enough layouts or correct layouts defined yet. They will be supported in the future.
!> Sometimes there isn't a layout that supports your exact build. In that case select `LAYOUT_all`.
## Step 3: Name Your Keymap
Call this keymap what you want.
?> If you are running into issues when compiling, it may be worth changing this name, as it may already exist in the QMK Firmware repo.
!> If your selected layout doesn't match your physical build leave the unused keys blank. If you're not sure which key is in use, for example you have a one backspace key but `LAYOUT_all` has 2 keys, put the same keycode in both locations.
When you're satisfied with your keymap or just want to work on it later, press the `Download this QMK Keymap JSON File` button. It will save your keymap to your computer. You can then load this .json file in the future by pressing the `Upload a QMK Keymap JSON File` button.
!> **CAUTION:** This is not the same type of .json file used for kbfirmware.com or any other tool. If you try to use this for those tools, or the .json from those tools with QMK Configurator, you will encounter problems.
