Slack Webhook setup

In order to send messages to a Slack channel, you need to create an Incoming Webhook: refer to the webhook ReadMe for details on how to setup this.

The Webhook url obtained will look like https://hooks.slack.com/services/xxx/yyy/zzzz. The last three parts, xxx/yyy/zzzz, need to be placed in the .env file, which must remain a local file as it contains API secrets.
