 Build with:
 
 ```
 $ klfc eurkey.json altgr.json control.json deadkeys.json -o output
-```  
+```
 
 The layout is split into multiple files:
 - `eurkey.json`, the main file, includes the None and Shift shift-states
 - `altgr.json`, includes the AltGr and Shift-AltGr shift-states, except dead keys
 - `control.json`, includes the Control shift-states, mostly for some control characters
-- `deadkeys.json`, (Shift-)AltGr shift states for the dead keys and dead key key pairs 
+- `deadkeys.json`, (Shift-)AltGr shift states for the dead keys and dead key key pairs

+## Converting a MSKLC file to JSON
+
+The [Microsoft Keyboard Layout Creator](https://www.microsoft.com/en-us/download/details.aspx?id=102134) (MSKLC) can export a keymap to a KLC file. KLFC currently not read such a file directly.
+
+MSKLC was used to extract the information from an installed EurKEY layout. MSKLC exports to KLC files, which KLFC can work with.
+
+To convert the KLC file from UCS2 (UTF-16) to UTF-8, you can use `iconv`. The additional `sed` command removes the Byte-Order-Mark.
+```
+iconv -f ucs2 -t utf8 eurkey.klc | sed '1s/^\xEF\xBB\xBF//' > eurkey.utf8.klc
+```
+
+KLFC can than convert the KLC file to a JSON file.
+```
+klfc --from-klc eurkey.utf8.klc --json eurkey.json
+```
+
+This JSON file has been split up by hand into the individual files to create a bit of logical separation.
