 On OSX, this can be accomplished by installing it through luarocks (run `sudo luarocks install ldoc`). Luarocks can be installed using [MacPorts](http://www.macports.org/). After installing that, the command would be `sudo port install luarocks`.
 
+Command line interface
+----------------------
+The Doodle3D API can be called using a terminal:
+
+```d3dapi p=/network/scan r=GET```
+
+Where the p parameter is the module you want to call and r is the method.
+Post request can be send using the same method:

 Changelog
+
+# 0.11.0 (12 jul 2017)
+# 0.11.0-c (10 jul 2017)
+- fix: Also closing file descriptor after removing current print file (commit 550e151)
+
+# 0.11.0-b (6 jul 2017)
+- show id of current print in d3dapi/info/status when printing in 'fetch' mode.
+- code reuse and cleanup for control, kill and status
+
+# 0.11.0-a (23 jun 2017)
+- Added 'fetch' functionality to let the WiFi-Box print from a remote server. This enables the WiFi-Box to print large g-code files. (yeah!)
+- Added support for the Renkforce RF100 printer.
+- Changed 'default startcode' to prevent Ultimaker 2 series to bump into platform [#21](https://github.com/Doodle3D/WiFi-Box/issues/21) when Ultimaker (original) is selected.
+- Changed default nozzle temperature from 230 to 210 °C.
+- Fixed corrupted endcode for delta printers.
+- Changed default endcode to cooldown to 0 after print instead of cooling down to preheat temperature.
+
+# 0.10.12
+# 0.10.12-b (12 jan 2017)
+- Post install update to config for changes in 0.10.10 (fixes print3d logging)
+
 # 0.10.12-a (26 jul 2016)
 - Added Ultimaker Original Plus (Thanks Remco)
 - Added extra usb drivers
