+Summary: An application that helps you write images to USB drives, no root required
+Description: |-
+    EtchDroid is an open-source application that helps you write images to USB drives.
+    You can use it to make a bootable GNU/Linux USB drive when your laptop is dead
+    and you're in the middle of nowhere.
+
+    Features:
+    * Supports raw disk images and most GNU/Linux distributions ISOs
+    * Supports most DMG disk images (beta)
+    * No root - everything is done within the bounds of the Android API
+    * Free as in freedom
+
+    Planned features:
+    * Write common GNU/Linux distro in streaming from the Internet without storing it on the device
+    * Support for Windows installation ISO (will likely require root)
+    * Support for Unetbootin-style image flashing
