How do I Edit an Existing Knowledge Article?
To edit an existing KA:
Go to the KA and click on the 'Edit Article' button on the right hand panel.

Make your revisions in the editor and then click the 'Update Article' button at the bottom of the page to push the revisions into production.

Alternatively, you can click the 'Save Draft' button to save your revisions but not push them into production.
Once the revisions have been pushed to production click on settings

Scroll down to 'Next Review Date' and using the calendar picker chose a date year from the current date.

Your KA has now been revised and renewed!
