+#### Windows
+
+To run the examples on Windows, compilation is the same, but the command to run the program is slightly different since the PATH environment variable in Windows is separated by semicolons `;` instead of `:`.
+
+For instance, to compile and run the KEM example, type:
+```
+$ javac -cp target/liboqs-java.jar examples/KEMExample.java
+$ java -Djava.library.path=target/ -cp target/liboqs-java.jar;examples/ KEMExample
+```
+
+Similarly, you can run the `SigExample` and `RandExample` located  in the [examples](./examples/) directory.
