+# Building wolfSSL JNI/JSSE (wolfssljni)
+- To build the native JNI shared library run "./java.sh"
+- To build the Java JAR library run "ant"
+- To build the JNI/JSSE examples run "ant examples"
+
+# Running JUnit tests
+- To run JUnit tests run "ant test"
+- All tests should pass without problems
+
+# Code Style
+- Keep lines under 80 characters maximum length
+- Only use multi-line comments, no "//" style ones
+- Remove any trailing white space
+- Use 4 spaces for one tab, no hard tabs
+
+# Source Code Organization
+- The source code is organized into the following directories:
+  - native: JNI source and header files
+  - src: Java source code
+  - src/java/com/wolfssl: com.wolfssl package JNI layer source code
+  - src/java/com/wolfssl/provider/jsse: com.wolfssl.provider.jsse package wolfJSSE source code
+  - src/test: JUnit test code
+  - src/test/com/wolfssl/test: com.wolfssl thin JNI wrapper JUnit test code
+  - src/test/com/wolfssl/provider/jsse/test: com.wolfssl.provider.jsse wolfJSSE provider JUnit test code
+  - build.xml: Ant build file
+  - pom.xml: Maven build file
+  - docs: Generated Javadoc files
+  - scripts/infer.sh: Script to run Facebook Infer static analysis
+  - IDE/Android: Android Studio example project files
+
+# Workflow
+- Make sure package compiles and all JUnit tests pass when you are making code changes
+- Maintain minimum Java compatibility down to Java 8
+
+# Example Code Guidelines for Writing New Code
+- All examples are placed under the "examples" directory
+- "examples/README.md" contains a list of examples and basic instructions
+- Directory "examples" contains JNI-level examples
+- Directory "examples/provider" contains JSSE-level examples
+- All examples should have two files:
+  - Example.java: Java source code
+  - Example.sh: Shell script to run the example
+- Examples will be run from the root directory
+- Example .jks files are located under "examples/provider"
+- Example .jks files are updated using the update-jks.sh script
+- RMI examples using wolfJSSE are under "examples/provider/rmi"
+- JSSE level examples do not need to call WolfSSL.loadLibrary(), that is called automatically inside wolfJSSE
+- JNI level examples do need to call WolfSSL.loadLibrary()
