+# Unicode Setup
+
+Unicode input in QMK works by inputting a sequence of characters to the 
+OS, sort of like a macro. Unfortunately, the way this is done differs 
+for each platform. Specifically, each platform requires a different 
+combination of keys to trigger Unicode input. Therefore, a 
+corresponding input mode has to be set in QMK.
+
+Documentation: [Feature Unicode](https://beta.docs.qmk.fm/features/feature_unicode#input-modes)
+
+On this keymap the default unicode mode it's `UC_LNX`.
+You can change it permanently tapping 2 times the KeyOne to select the next mode.
+
+## Unicode Mode List
+- UC_LNX
+- UC_OSX
+- UC_WIN
+- UC_WINC
+
+# Keymap
+To add more functionality to this Minimal Keyboard, 
+it's implemented the tap dance feature, so pressing the same key 
+multiples times will produce different emojis.
+
+## Key One
+
+- 1 Tap: `¯\_(ツ)_/¯`
+- 2 Taps: Switch Unicode Input Type
+
+## Key Two
+
+- 1 Tap: `ಠ_ಠ`
+- 2 Taps: `(ノಠ痊ಠ)ノ彡┻━┻`
+- 3 Taps: `╭∩╮(-_-)╭∩╮`
+- 4 Taps: `(づ￣ ³￣)づ`
+- 5 Taps: `(︺︹︺)`
