Installation

You can install the package using the Composer package manager. You can install it by running this command in your project root:

composer require fahl-design/log4php-slack-appender

Then create an incoming webhook for each Slack team you’d like to send messages to. You’ll need the webhook URL(s) in order to configure this package.

After you got your hook url add it as endpoint to your configuration
