 ## Post-installation Tasks
 
 For desktop users installing the binary, OrientDB is now installed and can be run through shell scripts found in the package `bin` directory of the installation.  For servers, there are some additional steps that you need to take in order to manage the database server for OrientDB as a service.  The procedure for this varies, depending on your operating system.
