 ===============
 Generate points to send over ZeroMQ to the Unreal Engine point cloud demo.
+
+Windows installation
+--------------------
+The best solution is to depend on the provided vendored libs:
+
+```toml
+zmq = { version = "0.9", features = ['vendored'] }
+```
+
+Trying to build our own zeromq is COMPLICATED. I don't understand the Windows ecosystem at all, 
+and I spent hours trying to get things working:
+
+* Install [Microsoft's vcpkg](https://github.com/Microsoft/vcpkg/) package manager.
+* `PS C:\dev\vcpkg> .\vcpkg.exe install czmq`
+* [Install CMake](https://cmake.org/download/) and add the bin directory (`C:\Program Files\CMake\bin`)
+  to the path (System properties > Advanced > Environment variables).
+  
+* Build:
+
+```
+mkdir build
+cd build
+cmake ..
+```
+
+* Then open the `.sln` file in Visual Studio and build... 
+* which gives you `dll` and `lib` files...
+* Add those to the windows Path...
+* (Not working)
