Explain the steps to create an 'Alert'

Grafana docs:

"Navigate to the panel you want to add or edit an alert rule for, click the title, and then click Edit. On the Alert tab, click Create Alert. If an alert already exists for this panel, then you can just edit the fields on the Alert tab. Fill out the fields. Descriptions are listed below in Alert rule fields. When you have finished writing your rule, click Save in the upper right corner to save alert rule and the dashboard. (Optional but recommended) Click Test rule to make sure the rule returns the results you expect"
