     * Document why in a comment when you do deviate

 * Instruct the user to set the environment variable `QMK_HOME` to have the firmware source checked out somewhere other than `~/qmk_firmware`.
+
+# Local CLI
+
+If you do not want to use the global CLI there is a local CLI bundled with `qmk_firmware`. You can find it in `qmk_firmware/bin/qmk`. You can run the `qmk` command from any directory and it will always operate on that copy of `qmk_firmware`.
+
+**Example**:
+
+```
+$ ~/qmk_firmware/bin/qmk hello
+Ψ Hello, World!
+```
+
+## Local CLI Limitations
+
+There are some limitations to the local CLI compared to the global CLI:
+
+* The local CLI does not support `qmk setup` or `qmk clone`
+* The local CLI always operates on the same `qmk_firmware` tree, even if you have multiple repositories cloned.
+* The local CLI does not run in a virtualenv, so it's possible that dependencies will conflict
+
+# CLI Commands
+
+## `qmk cformat`
+
+*dev mode*
+
+This command formats C code using clang-format. Run it with no arguments to format all core code, or pass filenames on the command line to run it on specific files.
+
+**Usage**:
+
+```
+qmk cformat [file1] [file2] [...] [fileN]
+```
+
+## `qmk compile`
+
+This command allows you to compile firmware from any directory. You can compile JSON exports from <https://config.qmk.fm>, compile keymaps in the repo, or compile the keyboard in the current working directory.
+
+**Usage for Configurator Exports**:
+
+```
+qmk compile <configuratorExport.json>
+```
+
+**Usage for Keymaps**:
+
+```
+qmk compile -kb <keyboard_name> -km <keymap_name>
+```
+
+**Usage in Keyboard Directory**:  
+
+Must be in keyboard directory with a default keymap, or in keymap directory for keyboard, or supply one with `--keymap <keymap_name>`
+```
+qmk compile
+```
+
+**Example**:
+```
+$ qmk config compile.keymap=default
+$ cd ~/qmk_firmware/keyboards/planck/rev6
+$ qmk compile
+Ψ Compiling keymap with make planck/rev6:default
+...
+```
+or with optional keymap argument
+
+```
+$ cd ~/qmk_firmware/keyboards/clueboard/66/rev4 
+$ qmk compile -km 66_iso
+Ψ Compiling keymap with make clueboard/66/rev4:66_iso
+...
+```
+or in keymap directory
+
+```
+$ cd ~/qmk_firmware/keyboards/gh60/satan/keymaps/colemak
+$ qmk compile
+Ψ Compiling keymap with make make gh60/satan:colemak
+...
+```
+
+**Usage in Layout Directory**:  
+
+Must be under `qmk_firmware/layouts/`, and in a keymap folder.
+```
+qmk compile -kb <keyboard_name>
+```
+
+**Example**:
+```
+$ cd ~/qmk_firmware/layouts/community/60_ansi/mechmerlin-ansi
+$ qmk compile -kb dz60
+Ψ Compiling keymap with make dz60:mechmerlin-ansi
+...
+```
+
+## `qmk flash`
+
+This command is similar to `qmk compile`, but can also target a bootloader. The bootloader is optional, and is set to `:flash` by default.
+To specify a different bootloader, use `-bl <bootloader>`. Visit <https://docs.qmk.fm/#/flashing>
+for more details of the available bootloaders.
+
+**Usage for Configurator Exports**:
+
+```
+qmk flash <configuratorExport.json> -bl <bootloader>
+```
+
+**Usage for Keymaps**:
+
+```
+qmk flash -kb <keyboard_name> -km <keymap_name> -bl <bootloader>
+```
+
+**Listing the Bootloaders**
+
+```
+qmk flash -b
+```
+
+## `qmk config`
+
+This command lets you configure the behavior of QMK. For the full `qmk config` documentation see [CLI Configuration](cli_configuration.md).
+
+**Usage**:
+
+```
+qmk config [-ro] [config_token1] [config_token2] [...] [config_tokenN]
+```
+
+## `qmk docs`
+
+This command starts a local HTTP server which you can use for browsing or improving the docs. Default port is 8936.
+
+**Usage**:
+
+```
+qmk docs [-p PORT]
+```
+
+## `qmk doctor`
+
+This command examines your environment and alerts you to potential build or flash problems. It can fix many of them if you want it to.
+
+**Usage**:
+
+```
+qmk doctor [-y] [-n]
+```
+
+**Examples**:
+
+Check your environment for problems and prompt to fix them:
+
+    qmk doctor
+
+Check your environment and automatically fix any problems found:
+
+    qmk doctor -y
+
+Check your environment and report problems only:
+
+    qmk doctor -n
+
+## `qmk json-keymap`
+
+Creates a keymap.c from a QMK Configurator export.
+
+**Usage**:
+
+```
+qmk json-keymap [-o OUTPUT] filename
+```
+
+## `qmk kle2json`
+
+This command allows you to convert from raw KLE data to QMK Configurator JSON. It accepts either an absolute file path, or a file name in the current directory. By default it will not overwrite `info.json` if it is already present. Use the `-f` or `--force` flag to overwrite.
+
+**Usage**:
+
+```
+qmk kle2json [-f] <filename>
+```
+
+**Examples**:
+
+```
+$ qmk kle2json kle.txt 
+☒ File info.json already exists, use -f or --force to overwrite.
+```
+
+```
+$ qmk kle2json -f kle.txt -f
+Ψ Wrote out to info.json
+```
+
+## `qmk list-keyboards`
+
+This command lists all the keyboards currently defined in `qmk_firmware`
+
+**Usage**:
+
+```
+qmk list-keyboards
+```
+
+## `qmk list-keymaps`
+
+This command lists all the keymaps for a specified keyboard (and revision).
+
+**Usage**:
+
+```
+qmk list-keymaps -kb planck/ez
+```
+
+## `qmk new-keymap`
+
+This command creates a new keymap based on a keyboard's existing default keymap.
+
+**Usage**:
+
+```
+qmk new-keymap [-kb KEYBOARD] [-km KEYMAP]
+```
+
+## `qmk pyformat`
+
+*dev mode*
+
+This command formats python code in `qmk_firmware`.
+
+**Usage**:
+
+```
+qmk pyformat
+```
+
+## `qmk pytest`
+
+*dev mode*
+
+This command runs the python test suite. If you make changes to python code you should ensure this runs successfully.
+
+**Usage**:
+
+```
+qmk pytest
+```

 The QMK CLI operates using the subcommand pattern made famous by git. The main `qmk` script is simply there to setup the environment and pick the correct entrypoint to run. Each subcommand is a self-contained module with an entrypoint (decorated by `@cli.subcommand()`) that performs some action and returns a shell returncode, or None.
 
+*Tip*: Enable dev mode by `qmk config user.developer=True`

 [MILC](https://github.com/clueboard/milc) is the CLI framework `qmk` uses to handle argument parsing, configuration, logging, and many other features. It lets you focus on writing your tool without wasting your time writing glue code.
