+###Keymaps with both Dvorak layout and QWER layout for HHKB JP.  
+
+1. The default layout is Dvorak.
+2. Use `Tog` to toggle between Dvorak and QWER
+3. Holding `NewCmd`, the original `LftCmd`,  will activate the `NewCmd` layer which means `NewCmd+key` is the same as `Cmd+key` in normal QWER layout.<sup>[1](#cmdTab)</sup>
+  - For example, no matter you are in Dvorak layout or QWER layout, you can use `Cmd+s` to save a currently editing file.
+4. `Symb` makes type symbols easier
+  - for example: `Symb+a` is `!`.
+5. `Spc+key` equals to `Shft+key` while using `Spc` alone will yield a space as usual.
+6. There's an extra `Tab` in the last line.
+    
+```

+HHKB Alternate Controller
+===
+
+An alternative controler for the HHKB designed by hasu.
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: HHKB Alternate Controller  
+Hardware Availability: https://geekhack.org/index.php?topic=12047.0  
+
+Make example for this keyboard (after setting up your build environment):
+
+    make hhkb/jp:default
+
+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.
