+Objective C Examples
+======
+
+The example in this directory show typical use of Objective C libraries,
+binaries and imports. Because they build iOS an application they can only be run
+on Mac OSX.
+
+Build the top-level application with
+`bazel build examples/objc:PrenotCalculator`, which when finished prints the
+path to the generated .ipa. which you can then install to your test device. The
+same build will also print the path to an Xcode project directory which you can
+open to continue working with the application in Xcode.
+
+Running `bazel build examples/objc:PrenotCalculatorInstruments` will build and
+run the application to obtain a screenshot, the path to which it then prints.
