-build:
-
-    export ANDROID_HOME=/path/to/android-sdk
-    ./update-ant-build.sh
-    ant clean debug
-
-Then the installable APK will be in **bin/ChatSecure-debug.apk**.

-### Eclipse setup
-
-1. Start by adding ChatSecureAndroid to Eclipse by going to _File_ -> _New_ ->
-_Project..._ -> _Android project from existing code_.
-
-2. Open the ChatSecureAndroid folder that was just cloned from git.
-
-3. Eclipse will next show a list of subprojects to import, all of the
-libraries with _New Project Name_ of **library** must be renamed after the
-project name, i.e. SlidingMenu, AndroidEmojiInput, ViewPagerIndicator.
-
-4. Click *Deselect All*.  The sample and example projects are not needed, and
-can cause conflicts.
-
-5. Select __ChatSecure__ again by clicking the top item in the list.
-
-6. Outside of Eclipse, open up the text file _project.properties_.  Then back
-in Eclipse, for each line that starts with `android.library.reference`, select
-that path from the list of included sub-projects in Eclipse.
-
-Now you should be ready to build ChatSecure!
