+## Cross-building
+
+RocksDB can be built as a single self contained cross-platform JAR. The cross-platform jar can be used on any 64-bit OSX system, 32-bit Linux system, or 64-bit Linux system.
+
+Building a cross-platform JAR requires:
+
+ * [Docker](https://www.docker.com/docker-community)
+ * A Mac OSX machine that can compile RocksDB.
+ * Java 7 set as JAVA_HOME.
+
+Once you have these items, run this make command from RocksDB's root source directory:
+
+    make jclean clean rocksdbjavastaticreleasedocker
+
+This command will build RocksDB natively on OSX, and will then spin up docker containers to build RocksDB for 32-bit and 64-bit Linux with glibc, and 32-bit and 64-bit Linux with musl libc.
+
+You can find all native binaries and JARs in the java/target directory upon completion:
+
+    librocksdbjni-linux32.so
+    librocksdbjni-linux64.so
+    librocksdbjni-linux64-musl.so
+    librocksdbjni-linux32-musl.so
+    librocksdbjni-osx.jnilib
+    rocksdbjni-x.y.z-javadoc.jar
+    rocksdbjni-x.y.z-linux32.jar
+    rocksdbjni-x.y.z-linux64.jar
+    rocksdbjni-x.y.z-linux64-musl.jar
+    rocksdbjni-x.y.z-linux32-musl.jar
+    rocksdbjni-x.y.z-osx.jar
+    rocksdbjni-x.y.z-sources.jar
+    rocksdbjni-x.y.z.jar
+
+Where x.y.z is the built version number of RocksDB.
+
+## Maven publication
+
+Set ~/.m2/settings.xml to contain:
+
+    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
+      <servers>
+        <server>
+          <id>sonatype-nexus-staging</id>
+          <username>your-sonatype-jira-username</username>
+          <password>your-sonatype-jira-password</password>
+        </server>
+      </servers>
+    </settings>
+
+From RocksDB's root directory, first build the Java static JARs:
+
+    make jclean clean rocksdbjavastaticpublish
+
+This command will [stage the JAR artifacts on the Sonatype staging repository](http://central.sonatype.org/pages/manual-staging-bundle-creation-and-deployment.html). To release the staged artifacts.
+
+1. Go to [https://oss.sonatype.org/#stagingRepositories](https://oss.sonatype.org/#stagingRepositories) and search for "rocksdb" in the upper right hand search box.
+2. Select the rocksdb staging repository, and inspect its contents.
+3. If all is well, follow [these steps](https://oss.sonatype.org/#stagingRepositories) to close the repository and release it.
+
+After the release has occurred, the artifacts will be synced to Maven central within 24-48 hours.
