   The archive binaries can be installed by anyone (not only root users), in any location that you can write to.

   The `.tar.gz` archive file (also called a tarball) is a file that can be simultaneously uncompressed and extracted in one step.

2. Change directory to the location where you would like the Server JRE to be installed.

3. Move the `.tar.gz` archive binaries to the current directory.

4. Unpack the tarball and install the Server JRE.

5. Delete the `.tar.gz` file if you want to save disk space.
