+# Install on Windows
+
+This document collects the different options available on Windows to bring
+Gazebo into a Windows system.
+
+Windows is not a fully officially supported platform by Open Robotics for
+Gazebo. Open Robotics guarantees that the code is compatible with compilations
+on Windows but there are no packages officially available. Since Gazebo is open
+source, the Gazebo Community provides distribution using different projects.
+
+## Community support
+
+The Gazebo Community runs different projects to facilitate the
+Windows installation providing all the dependencies and patch the code to solve
+problems at runtime (help from Open Robotics is usually provided).
+
+For the different Community projects available,
+[checkout the issue tracker](https://github.com/osrf/gazebo/issues/2901). Below
+is a quick overview of some of them.
+
+### Gazebo on Windows via conda-forge
+
+[conda-forge](https://conda-forge.org/) is a collection of packages to be used
+with the conda package manager.
+
+General feedback on using conda-forge is collected
+[in this Gazebo issue](https://github.com/osrf/gazebo/issues/2899).
+
+For contributions or bug reports on using Gazebo with conda the best place is the
+[conda-forge issue tracker](https://github.com/conda-forge/gazebo-feedstock).
+
+### Gazebo on Windows via vcpkg
+
+[vcpkg](https://github.com/microsoft/vcpkg) is a package manager oriented to C
+and C++ libraries and tools managed by Microsoft. There is a port for
+[Gazebo](https://github.com/microsoft/vcpkg/tree/master/ports/gazebo).
+
+General feedback on using vcpkg is collected
+[in this Gazebo issue](https://github.com/osrf/gazebo/issues/3202).
+
+For contributions or bug reports on using Gazebo with vcpkg the best place is the
+[vcpkg issue tracker](https://github.com/microsoft/vcpkg/issues)
+
+### Gazebo on Windows via WSL (Windows Subsystem for Linux)
+
+[WSL](https://docs.microsoft.com/en-us/windows/wsl/install) is a compatibility
+layer for running Linux binary executables on Windows 10 and newer.
+
+The [Project DAVE](https://github.com/Field-Robotics-Lab/dave/wiki) provides
+[detailed instructions](https://github.com/Field-Robotics-Lab/dave/wiki/Install-on-Windows-using-WSL2) 
+to setup WSL and install Gazebo together with ROS Noetic using Ubuntu Linux 
+installed on Windows. ROS installation can be avoided and just follow 
+instructions until the point of installing ROS Noetic packages and
+use apt to install `libgazebo11-dev`.
