Write docs for dev mode

Force scss compile when environment is development #39

When wp_get_environment_type() returns that it is in development mode, either from reading the define in the wp-config.php or from reading the getenv, the scss will always be compiled, no matter if changes have been made.
To set the environment to development, add the following line to your wp-config.php
define('WP_ENVIRONMENT_TYPE', 'development');

• Docs for recompile
• Docs for source map
