+# Java Bindings Developer documents.
+
+This document is meant to anyone looking to build the Java bindings from source, test a build locally and perform a release.
+
+## Building locally
+
+Maven is the build tool used by the project. Maven version of 3.8 or higher is recommended. Make sure the **mvn** 
+is available on the command path.
+
+The project builds to Java version 11 target so make sure that a JDK at version 11 or newer is installed.
+
+### Setting up location of native shared libraries
+The property **native.libs.location** in pom.xml may need to be set:
+```
+    <properties>
+        ...
+        <native.libs.location>C:\Users\felix\dev\gpt4all_java_bins\release_1_1_3_Jun22_2023</native.libs.location>
+    </properties>
+```
+All the native shared libraries bundled with the Java binding jar will be copied from this location.
+The directory structure is **native/linux**, **native/macos**, **native/windows**. These directories are copied
+into the **src/main/resources** folder during the build process.
+
+For the purposes of local testing, none of these directories have to be present or just one OS type may be present.
+
+If none of the native libraries are present in **native.libs.location** the shared libraries will be searched for
+in location path set by **LLModel.LIBRARY_SEARCH_PATH** static variable in Java source code that is using the bindings.
+
+Alternately you can copy the shared libraries into the **src/resources/native/linux** before 
+you build, but note **src/main/resources/native** is on the .gitignore, so it will not be committed to sources.
+
+### Building
+
+To package the bindings jar run:
+```
+mvn package
+```
+This will build two jars. One has only the Java bindings and the other is a fat jar that will have required dependencies included as well.
+
+To package and install the Java bindings to your local maven repository run:
+```
+mvn install
+```
+
+### Using in a sample application
+
+You can check out a sample project that uses the java bindings here:
+https://github.com/felix-zaslavskiy/gpt4all-java-bindings-sample.git
+
+1. First, update the dependency of java bindings to whatever you have installed in local repository such as **1.1.4-SNAPSHOT**
+2. Second, update **Main.java** and set **baseModelPath** to the correct location of model weight files.
+
+3. To make a runnable jar run:
+```
+mvn package
+```
+
+A fat jar is also created which is easy to run from command line:
+```
+java -jar target/gpt4all-java-bindings-sample-1.0-SNAPSHOT-jar-with-dependencies.jar
+```
+
+### Publish a public release.
+
+For publishing a new version to maven central repository requires password and signing keys which F.Z. currently maintains, so
+he is responsible for making a public release.
+
+The procedure is as follows:
+
+For a snapshot release
+Run:
+```
+mvn deploy -P signing-profile
+```
+
+For a non-snapshot release
+Run:
+```
+mvn clean deploy -P signing-profile,release
+```
