+# MakeItFlow - Arduino Interaction
+
+Modifications to FlowCloud's MakeItFlow android application, allowing more complex interactions with Arduino sketches running on the WiFire.
+
+The original MakeItFlow can be found on the [Play Store](https://play.google.com/store/apps/details?id=com.imgtec.hobbyist) and the source can be found on the [FlowCloud developer website](http://flow.imgtec.com/developers/).
+
+This modified app is a companion to the [FlowCloud on Arduino blog]().
+
+Modifications include showing returned data from the WiFire and (on the command parameters branch) allowing parameters to be passed along with commands to the WiFire.
+
+## Using the modified app
+
+The sources can be imported into Android Studio. The project uses gradle as a build system, so everything should run smoothly. 
+
+Releases can also be downloaded from the [releases page]().
