+
+epaew's Enhanced Dvorak layout for Japanese Programmer
+
+## Layout overview
+This is a sample. You can swap any symbol keys and modifier keys.
+
+- Base layer (for ansi layout)
+```
+  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
+      `  , !  , @  , #  , $  , %  , ^  , &  , *  , (  , )  , [  , ]  ,  BSPC   ,
+  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+

+  //+------++---++---++---++---++---++---++---++---++---++---++---++---+-------+
+      CAPS  , A  , O  , E  , I  , U  , D  , T  , N  , S  , M  , -  ,    ENT    ,
+  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-----------+
+       LSFT   , ;  , X  , C  , V  , Z  , B  , H  , J  , K  , L  ,     RSFT     ,
+  //+------+--+---++----++---+----+----+----+----+-+--+---++----++------+------+
+      LCTL , LGUI , LALT ,          SPACE          , RALT , RGUI , MENU , RCTL
+  //+------+------+------+-------------------------+------+------+------+------+
+```
+- Base layer (for iso layout)
+  - Two C keys are placed, it's on purpose.
+```
+  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
+      `  , !  , @  , #  , $  , %  , ^  , &  , *  , (  , )  , [  , ]  ,  BSPC   ,
+  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+
+      TAB  , '  , ,  , .  , P  , Y  , F  , G  , R  , W  , C  , /  , =  ,
+  //+------++---++---++---++---++---++---++---++---++---++---++---++---++
+      CAPS  , A  , O  , E  , I  , U  , D  , T  , N  , S  , M  , ;  , -  , ENT  ,
+  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+------+
+       LSFT   , Q  , X  , C  , V  , Z  , B  , H  , J  , K  , L  , \  ,  RSFT   ,
+  //+------+--+---++----++---+----+----+----+----+-+--+---++----++---+--+------+
+      LCTL , LGUI , LALT ,          SPACE          , RALT , RGUI , MENU , RCTL
+  //+------+------+------+-------------------------+------+------+------+------+
+```
+- Additional layer (common, blanks are transparent)
+```
+  //+----+----+----+----+----+----+----+----+----+----+----+----+----+---------+
+         ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,    ,         ,
+  //+----+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+-------+
+           , AI , OU , EI ,    ,    ,    ,    ,    ,    ,    ,    ,    ,       ,
+  //+------++---++---++---++---++---++---++---++---++---++---++---++---+-------+
+            , A  , O  , E  , I  , U  ,    , Y1 , N  , Y2 ,    ,    ,           ,
+  //+-------+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-+--+-----------+
+              ,ANN ,ONN ,ENN ,INN ,UNN ,    ,    ,    ,    ,    ,              ,
+  //+------+--+---++----++---+----+----+----+----+-+--+---++----++------+------+
+           ,      ,      ,                         ,      ,      ,      ,
+  //+------+------+------+-------------------------+------+------+------+------+
+```
+
+ And you can see [my iris keyboard layout](../../keyboards/iris/keymaps/edvorakjp/keymap.c) for sample implementation, too.
+
+## for Japanese
+
+- 日本語入力用のキーを追加
+  - IME 切り替えキー
+    - 長押しでレイヤー切り替え、短押しでIME切り替え
+    - macOS(かな/英数)、Windows(Alt+\`)の両方に対応
+  - DvorakJP(<http://www7.plala.or.jp/dvorakjp/>)を参考にした日本語入力用キーの導入
+    - 拗音入力用のYキーを追加配置
+    - 二重母音入力用のキー(AI, OU, EI)
+    - 撥音入力用のキー(ANN, ONN, ENN, INN, UNN)
+    - いずれかの子音を押下することで Additional layer が出現し、いずれかの母音を押下することで Base layer に戻ります（※1※2）
+      - ※1促音の入力に使うため、また連続で同じ指での打鍵を減らすために、  
+        FGRDTNBHJ を押下した場合はy1が、それ以外の子音を押下した場合はy2が出現しません
+      - ※2撥音の入力のため、nを2連打すると、Base layerに戻ります
+- Define some custom keys for typing Japanese
+  - IME switching
+    - act as LOWER/RAISE when hold, act as IME switching when tapped
+    - for macOS(かな/英数), for Windows(Alt+\`)
+  - oneshot combination keys, inspired from DvorakJP (<http://www7.plala.or.jp/dvorakjp/>)
+    - additional Y key to enter a contracted sound
+    - diphthong keys (AI, OU, EI)
+    - syllabic nasal (ANN, ONN, ENN, INN, UNN)
+    - Additional layer is appeared when you taps any consonant keys, and disappeared when you taps any diphthong keys.
+
+## for Programmer
+
+- Dvorak 配列をベースに、ショートカットでよく利用される XCV は QWERTY 配列の位置を維持
+- Vimユーザのために、HJKL キーを横並びで配置
+- デフォルトレイヤーには、数字キーの代わりに記号 `!@#$%^&*()` を配置
+
+- mainly based on Dvorak layout, but XCV is available in the same position of QWERTY layout
+- HJKL is lining side by side, for Vim users
+- we can type `!@#$%^&*()` keys without shift keys in base layer
