 mkbd65 case
 ===========
 
-_The case for mkbd65 is still a work in progress!_
+_The case  and key set for mkbd65 is still a work in progress!_
 
+This is the case for mkbd65. It is build using [OpenSCAD][openscad] to be able to generate multiple cases fitting
+different phones from a single file.
+Follow the guide at https://mkbd65.xengi.de to build a case for your phone.
+
+## Generate a case
+
+_TBA_
+
+## Generate a key set
+
+To generate the key set you can either use a predefined layout or generate your own. There are two predefined layouts
+for English US International and German. You can generate the 3D files for them with the following commands:
+
+```shell
+make keys:en-us-intl
+make keys:de
+```
+
+This will generate the neccessary 3MF and STL files that you can use for your 3D printers slicer software. I recommend a
+flexible filament like Filaflex 95A for the best typing experience.
+
+### Custom layout
+
+If you want to build your own custom layout follow the instruction in the file `custom_keyset.scad`. It will explain how
+to write the openscad code for a key set and generate the 3MF and STL files. You can use any of the keys from a 5x14
+matrix and also combine them however you like. Remember that you have to duplicate the keys in the config of the QMK
+software for every non 1x1 key too. Because electrically every switch is still a single unique key and gets detected as
+such.
+
+So if you want to create a 3x1 space bar at position (0, 5) you can create a key cap by using `key(x=0, y=5, w=3)`. In
+the QMK config you have to create 3 distinct space bar keys next to each other.
+
+In theory the maximum width of a key is 3. You can use more then that but the key will get sliced at different points to
+avoid accidental duble presses of the switches underneath.

+ * Every phone file must expose the following variables and modules:
+ * - phone_width: the phone width in mm
+ * - phone_length: the phones length in mm
+ * - phone_thickness: the phones thickness in mm
+ * - phone_corner_rad: the radius of the phones corners in mm
+ * - phone_body: module creating the phones body centered around the origin
+ * - camera_bump: module creating the phones camera bump to cut it out from the case
+ *     
+ * If you hold youphone in landscape the longer edge is considered it's width/x axis.
+ * The short edge is therefore the length/y axis. The thickness should be self explanatory.

+ * The phones main body (w/o camera bump) is centered on the x and y axis. The phones back

+ * The bump and flash light cone are used to subtract them from the case.
