+# Ivy iOS App source
+
+This directory contains the source code to the Ivy iOS app.
+
+To build, first create the mobile.framework out of the Go
+implementation of Ivy. Run:
+
+```
+ go get robpike.io/ivy
+ gomobile bind -target=ios robpike.io/ivy/mobile
+```
+
+Place the mobile.framework directory in this directory, and
+then open ivy.xcodeproj in Xcode.
