+### How to compile/use this example:
+
+1. Follow "Building from source" section from README.md in the root of this git repository
+(the linking step/example from that section does not apply to this example)
+
+2. Create the java library .jar file:
+
+```
+make host_jar_release
+```
+
+for other `host_jar` variants see Makefile in the root of this git repository
+
+2. Copy the output .jar to this directory:
+
+```
+cp lib/lib/release/linux-x86_64/zt.jar examples/java/simpleExample/
+```
+
+3. Now you can compile this example:
+
+```
+cd src
+javac -cp ../zt.jar ./com/zerotier/libzt/javasimpleexample/*.java 
+```
