+Android on Windows 10
+~~~~~~~~~~~~~~~~~~~~~
+
+To use buildozer in Windows 10 you need first to enable Windows Subsystem for Linux (WSL) and install a Linux distribution: https://docs.microsoft.com/en-us/windows/wsl/install-win10.
+
+These instructions were tested with WSL 1 and Ubuntu 18.04 LTS. 
+
+With WSL and Ubuntu installed on your Windows 10 machine, open Ubuntu and run these commands:
+
+::
+
+    sudo apt update
+    sudo apt install -y git zip unzip openjdk-8-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5 cmake libffi-dev libssl-dev
+    # Use here the python version you need
+    sudo apt install -y python3.7-venv
+    # Create a folder for buildozer
+    mkdir /mnt/c/buildozer
+    cd /mnt/c/buildozer
+    python3.7 -m venv venv-buildozer
+    source venv/bin/activate
+    python -m pip install --upgrade pip
+    python -m pip install --upgrade wheel
+    python -m pip install --upgrade cython 
+    python -m pip install --upgrade virtualenv 
+    python -m pip install --upgrade buildozer
+    # Add the following line at the end of your ~/.bashrc file
+    export PATH=$PATH:~/.local/bin/
+    # Restart your WSL terminal to enable the path change
+
+Now you need to install the Windows version of ADB (Android Debug Bridge):
+
+- Go to https://developer.android.com/studio/releases/platform-tools and click on "Download SDK Platform-Tools for Windows".
+
+- Unzip the downloaded file to a new folder. For example, "C:\\platform-tools".
+
+Before Using Buildozer
+----------------------
+
+If you wish, clone your code to a new folder, where the build process will run. You don't need to create a virtualenv for your code requirements. But just add these requirements to a configuration file called buildozer.spec as you will see in the following sections.
+
+Before running buildozer in your code folder, remember to go into the buildozer folder and activate the buildozer virtualenv.
