-As mentioned above, there are some shortcuts, when you are in a:
-
-* `keyboard` folder, the command will automatically fill the `<keyboard>` part. So you only need to type `<subproject>-<keymap>-<target>`
-* `subproject` folder, it will fill in both `<keyboard>` and `<subproject>`
-* `keymap` folder, then `<keyboard>` and `<keymap>` will be filled in. If you need to specify the `<subproject>` use the following syntax `<subproject>-<target>`
-  * Note in order to support this shortcut, the keymap needs its own Makefile
-* `keymap` folder of a `subproject`, then everything except the `<target>` will be filled in
-
 The `<target>` means the following
 * If no target is given, then it's the same as `all` below
-* `all` compiles the keyboard and generates a `<keyboard>_<keymap>.hex` file in whichever folder you run `make` from. These files are ignored by git, so don't worry about deleting them when committing/creating pull requests.
-* `dfu`, `teensy` or `dfu-util`, compile and upload the firmware to the keyboard. If the compilation fails, then nothing will be uploaded. The programmer to use depends on the keyboard. For most keyboards it's `dfu`, but for Infinity keyboards you should use `dfu-util`, and `teensy` for standard Teensys. To find out which command you should use for your keyboard, check the keyboard specific readme. **Note** that some operating systems needs root access for these commands to work, so in that case you need to run for example `sudo make dfu`.
+* `all` compiles as many keyboard/revision/keymap combinations as specified. For example, `make planck-rev4-default-all` will generate a single .hex, while `make planck-rev-all` will generate a hex for every keymap available to the planck.

-There are 5 different `make` and `Makefile` locations:
-
-* root (`/`)
-* keyboard (`/keyboards/<keyboard>/`)
-* keymap (`/keyboards/<keyboard>/keymaps/<keymap>/`)
-* subproject (`/keyboards/<keyboard>/<subproject>`)
-* subproject keymap (`/keyboards/<keyboard>/<subproject>/keymaps/<keymap>`)
-
-The root contains the code used to automatically figure out which keymap or keymaps to compile based on your current directory and commandline arguments. It's considered stable, and shouldn't be modified. The keyboard one will contain the MCU set-up and default settings for your keyboard, and shouldn't be modified unless you are the producer of that keyboard. The keymap Makefile can be modified by users, and is optional. It is included automatically if it exists. You can see an example [here](https://github.com/qmk/qmk_firmware/blob/master/doc/keymap_makefile_example.mk) - the last few lines are the most important. The settings you set here will override any defaults set in the keyboard Makefile. **The file is required if you want to run `make` in the keymap folder.**
-
-For keyboards and subprojects, the make files are split in two parts `Makefile` and `rules.mk`. All settings can be found in the `rules.mk` file, while the `Makefile` is just there for support and including the root `Makefile`. Keymaps contain just one `Makefile` for simplicity.

 ## Customizing Makefile options on a per-keymap basis
 
-If your keymap directory has a file called `Makefile` (note the filename), any Makefile options you set in that file will take precedence over other Makefile options for your particular keyboard.

-So let's say your keyboard's makefile has `BACKLIGHT_ENABLE = yes` (or maybe doesn't even list the `BACKLIGHT_ENABLE` option, which would cause it to be off). You want your particular keymap to not have the debug console, so you make a file called `Makefile` and specify `BACKLIGHT_ENABLE = no`.

 Notice how the `k11` and `KC_NO` switched places to represent the wiring, and the unused final column on the bottom row. Sometimes it'll make more sense to put a keyswitch on a particular column, but in the end, it won't matter, as long as all of them are accounted for. You can use this process to write out the `KEYMAP` for your entire keyboard - be sure to remember that your keyboard is actually backwards when looking at the underside of it.

 The basis of a keymap is its layers - by default, layer 0 is active. You can activate other layers, the highest of which will be referenced first. Let's start with our base layer.
