+### Windows notes
+
+This doesn't work on Windows. At all. JNI and native binaries need to be built and the install paths need to be figured out.
+
+### Linux notes
+
+JNI and native bindings will be installed in `/usr/local/lib` and the headers will be installed in `/usr/local/include`. If you don't have write access to these folders, you can run the installer with 
+
+`sudo java -Duser.home=$HOME -jar ...`
+
+Make sure that `/usr/local/lib` is on `LD_LIBRARY_PATH` or the JNI bindings won't be loaded by the JVM.
