+# Jars.
+
+This directory is responsible to generate the jar files for the Arrow components that depend on C++ shared libraries to execute.
+
+The Arrow C++ libraries are compiled both on MacOS and Linux distributions, with their dependencies linked statically, and they are added
+in the jars at the end, so the file can be used on both systems.
+
+## Linux Docker Image
+To compile the C++ libraries in Linux, a docker image is used. 
+It is created used the **ci/docker/java-bundled-jars.dockerfile** file. 
+If it is necessary to add any new dependency, you need to change that file.
