# Initial Setup Commands

Before you can perform tasks from the command line, you must first set up a configuration for the harness to use. You can set up a configuration by performing at least one of the following:

1. Specify an existing configuration (`.jti`) file. You are not required to specify either a test suite or a work directory.
2. Specify an existing work directory and a configuration file. You are not required to specify a test suite.
3. Open a test suite, create an empty work directory, and specify a configuration file.

After setting up a configuration, you can then change specific values for your specific requirements. See Setting Specific Values for the commands used to modify the values in the configuration.

You can include commands in any combination on the command line provided the initial set-up commands are specified before any other commands in the command line.

You can use any of the following commands to set up a configuration for the harness to use when performing tasks:

- `config` - Specifies an existing configuration file. See Specifying a Configuration File With `config` for a detailed description of this command.
- `workDirectory` or `workDir` - Specifies an existing work directory or to create a new work directory. See Specifying a Work Directory With `workDir` for a detailed description of this command.
- `testSuite` - Used to specify a test suite. See Specifying a Test Suite With `testSuite` for a detailed description of this command.
- `open` - Specifies a test suite, work directory, configuration file, or parameter file. See Specifying a Test Suite, Work Directory or Configuration With `open` for a detailed description of this command.
