Instructor comes with a set of configuration files and prompt templates that you can publish to your project directory. There are 2 ways to set up the location of Instructor’s configuration directory:
  • Using Settings class method setPath()
  • Using environment variable (recommended)
To check how to publish configuration files to your project see Setup section.

​
Setting Configuration Path via Settings Class

You can set Instructor configuration path using the Settings::setPath() method: 
<?php
use Cognesy\Config\Settings;

Settings::setPath('/path/to/config');
?>
// @doctest id="4631"

​
Setting Configuration Path via Environment Variable

You can set the path to Instructor’s configuration directory in your .env file: 
INSTRUCTOR_CONFIG_PATHS='/path/to/config/,another/path'
# @doctest id="10cd"

​
Configuration Location Resolution

Instructor uses a configuration directory with a set of .php files to store its settings, e.g. LLM provider configurations. Instructor will look for its configuration location in the following order:
  • If Settings::setPath() has been called, it will use that custom path list,
  • If INSTRUCTOR_CONFIG_PATHS (or INSTRUCTOR_CONFIG_PATH) environment variable is set, it will use that value,
  • Finally, it will default to the directory, which is bundled with Instructor package (under /config) and contains default set of configuration files.
