## Installation Process

This chapter describes how to install cosTime in an Erlang Environment.

### Preparation

Before starting the installation process for cosTime, the application Orber must be running.

### Configuration

When using both the Time and TimerEvent Services the cosTime application first must be installed using cosTime:install_time() and cosTime:install_timerevent(), followed by cosTime:start(). Now we can choose which can start the servers by using cosTime:start_time_service(Tdf, Inaccuracy) and cosTime:start_timerevent_service(TimeService).
