+= ViToni's keymap for GMMK Pro ISO
+
+== Layout
+Based on the stock layout but making use of CAPS as FN similar to laptop keyboards.
+This frees up the left row for other uses (although not remapped yet).
+Since both Delete and Insert are used for coding they are part of the CAPS layer as well.
+
+The differences are as follows:
+
+=== Layer 0 (`_BASE`)
+Mostly stock + CAPS goes to layer `_MOV`.
+FN toggles the layer `_RGB`.
+
+=== Layer 1 (`_MOV`), accessed by pressing `CAPS` on layer `_BASE`

+
+== RGB light
+
+The code customizing RGB light usage is decribed here:
+
+* link:../../../../../../users/vitoni/readme.adoc[/users/vitoni/readme.adoc]
+
+When using  `RGB_DISABLE_TIMEOUT` addtional options are available:
+
+* `RGB_FADE_IN` makes the RGB lights fade in instead of setting the value/brightness to 100% (implicitly due to HSV including the brightness) when resuming after RGB lights have been turned off.
+Fade in occurs when the keyboard is initialized and when the RGB brightness has been changed (e.g. suspending, fade out, etc.).
+* `RGB_DISABLE_WITH_FADE_OUT` activates fade out before the keyboard is disabled by `RGB_DISABLE_TIMEOUT`.
+
+Parameters used to define the behavior are:
+[%header]
+|===
+|Key | Default | Description
+
+| RGB_MATRIX_MAXIMUM_BRIGHTNESS
+| 200 (&lt;= UNIT8_MAX)
+| Maximum assumed value for brightness.
+Used to calculate lead time for fade out before suspend timeout.
+
+|===
+
+`RGB_IDLE_TIMEOUT` enables fading out after being idle for the defined time and allows
+* `RGB_IDLE_BREATHE` also activates a brethe effect while idling.
+
+[%header]
+|===
+|Key | Default | Description
+
+|RGB_IDLE_TIMEOUT
+|4500
+|Time in milliseconds without activity before considered to be idle.
+
+|RGB_IDLE_MINIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` / 5
+|Brightness value RGB is dimmed to when starting to idle. +
+When breathing used as the lower bound of the brightness value.
+
+|RGB_IDLE_MAXIMUM_BRIGHTNESS
+|`RGB_MATRIX_MAXIMUM_BRIGHTNESS` * 2/5
+|Upper bound of brightness value of the RGB light while breathing.
