+# Custom mapping for the Drop Alt Keyboard.
+
+A really simple set of changes/fixes
+
+# Features and changes:
+
+## *ESC is now Grave Escape.*
+Changes KC_ESC for grave escape - Escape key is also `/~ when used with the modifier key.
+
+## *RGB timer switch off*
+
+There is a timer that turns off RGB lighting after a set time. This is defined by 
+
+    #define  IDLE_TIMER_DURATION  20000  //how many milliseconds before RGB turns off
+
+## *Keyboard chatter fix*
+
+I have left the debounce settings and instead changed
+
+    wait_us(1); //Delay for output
+to 40 instead of 1 which works for other keyboards as I was getting lots of keyboard chatter on all keys previously. 20 seemed to still let key chatter go through. Seems to be working well since.
