@@ -17,7 +17,102 @@ As the name suspects, it is based on QT (5.15.X).
 We have a CI setup that checks compilation on ubuntu. You can look at the steps it performs to build and run QOpenHD.
 Other platforms than Linux are not supported right now.
 
-# Manual Building / MAVSDK
+# Building QOpenHD Locally in QT (GSTREAMER MIGHT NOT BE REQUIRED as things progress)
+#### Mac
+
+1. Install Xcode from the Mac App Store.
+
+2. Install Qt using the [Qt online installer](https://www.qt.io/download-qt-installer)
+
+3. Have the Qt Installer download Qt 5.15.0+ for Mac, and Qt Creator
+
+4. Clone the source code:
+
+    git clone --recurse-submodules https://github.com/OpenHD/QOpenHD.git
+
+If you aren't using git from the command line but using a GUI git client instead, make sure
+you update the submodules or QOpenHD will not build properly.
+    
+
+Once you have those steps done you can open `QOpenHD.pro` with Qt Creator, build and run it.
+
+#### iOS
+
+1. Install Xcode from the Mac App Store.
+
+2. Install Qt using the [Qt online installer](https://www.qt.io/download-qt-installer)
+
+3. Have the Qt Installer download Qt 5.15.0+ for iOS, and Qt Creator
+
+4. You will need an Apple developer membership to install directly to an iOS device
+
+5. Clone the source code:
+
+    git clone --recurse-submodules https://github.com/OpenHD/QOpenHD.git
+
+If you aren't using git from the command line but using a GUI git client instead, make sure
+you update the submodules or QOpenHD will not build properly.
+
+Once you have those steps done you can open `QOpenHD.pro` with Qt Creator, build and run it.
+
+#### Windows
+
+1. Install Visual Studio 2019 (free)
+
+2. Install Qt using the [Qt online installer](https://www.qt.io/download-qt-installer)
+
+3. Have the Qt Installer download Qt 5.15.0+ and Qt Creator
+
+4. Download the [GStreamer development kit](https://gstreamer.freedesktop.org/download/) for Windows, both the Runtime and Development packages. You *must use* the 32-bit MinGW packages, NOT the one labeled MSVC, and it should be version 1.14.4. (QT will look for gstreamer in c:/gstreamer/1.0/x86 )
+
+5. Clone the source code:
+
+    git clone --recurse-submodules https://github.com/OpenHD/QOpenHD.git
+
+If you aren't using git from the command line but using a GUI git client instead, make sure
+you update the submodules or QOpenHD will not build properly.
+
+Once you have those steps done you can open `QOpenHD.pro` with Qt Creator, build and run it.
+
+#### Linux
+
+1. Install Qt using the [Qt online installer](https://www.qt.io/download-qt-installer)
+
+2. Have it download Qt 5.15.0+ for Linux 
+
+3. Install GStreamer development packages from the package manager. On Ubuntu this would be `apt install gstreamer1.0-gl libgstreamer1.0-dev libgstreamer-plugins-good1.0-dev gstreamer1.0-plugins-good libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-qt`. Those should pull in any others that are needed as well.
+
+4. Clone the source code:
+
+    git clone --recurse-submodules https://github.com/OpenHD/QOpenHD.git
+
+If you aren't using git from the command line but using a GUI git client instead, make sure
+you update the submodules or QOpenHD will not build properly.
+
+Once you have those steps done you can open `QOpenHD.pro` with Qt Creator, build and run it.
+
+#### Android
+
+1. Install [Android Studio](https://developer.android.com/studio)
+
+2. Use Android Studio to install Android SDK level 28, along with NDK r18b and the associated build toolchain.
+
+3. Install Qt using the [Qt online installer](https://www.qt.io/download-qt-installer)
+
+4. Have the Qt Installer download Qt 5.15.0+ *for Android*, not for the OS you're building on.
+
+5. Clone the source code:
+
+    git clone --recurse-submodules https://github.com/OpenHD/QOpenHD.git
+
+If you aren't using git from the command line but using a GUI git client instead, make sure
+you update the submodules or QOpenHD will not build properly.
+
+You can then open `QOpenHD.pro` using Qt Creator and set up the Android kit (left side, click the Projects tab), build and run the app on your device.
+
+
+
+# Building MAVSDK (REQUIRED)
 QOpenHD relies on MAVSDK library. After recursively cloning qopenhd build this library:
 
 `cd lib/MAVSDK`
