+Building TextSecure
+===================
+
+Fetch ActionBarSherlock:
+
+    git clone --branch 4.2.0 git://github.com/JakeWharton/ActionBarSherlock.git ../ActionBarSherlock
+
+Configure ActionBarSherlock for your android target:
+
+    android update project --path ../ActionBarSherlock/library --target 1
+
+Configure TextSecure for your android target, linking to ASB:
+
+    android update project --path . --target 1 --library ../ActionBarSherlock/library
+
+Finally, both codebases must share the android-support jar. As TextSecure's is newer, use it:
+
+    cp libs/android-support-v4.jar ../ActionBarSherlock/library/libs/android-support-v4.jar
+
+Assuming your android toolchain is correctly configured, it should now be possible to build the TextSecure apk.
