 ZeroTier Integrations
 ====
 
-This is a collection of example projects demonstrating how you can embed or integrate ZeroTier functionality directly into your applications and games with *little to no change to your code*. 
+If you want everything built at once, type `make all` and go play outside for a little while, we'll copy all of the targets into the `build` directory for you along with specific instructions on how to use each binary.
+
+*NOTE: For iOS/OSX Frameworks and Bundles to build, you will need XCode command line tools `xcode-select --install`, for Android JNI libraries to build you'll need to install [Android Studio](https://developer.android.com/studio/index.html), if you don't have these things install we will detect that and just skip those builds automatically.*
+
+Below are the specific instructions for each integration requiring little to no modification to your code. Remember, with a full build we'll put a copy of the appropriate integration instructions in the resultant binary's folder for you anyway. 
 
 For more support on these integrations take a look at the [docs](../docs) folder. Specifically the [Shims](../docs/shims_zt_sdk.md) and [SDK API](../docs/zt_sdk.md) overviews.
