Using Tabs is pretty simple and straightforward. You just place {tab} tags around the text (rich content) that should show up in tabs.

You don't need to go into html view, you can use this right in your WYSIWYG editor.

Every block of content should be preceded with a starting {tab} tag, like:

{tab title="Title of the tab"}

And place a closing {/tabs} tag after the last tab content block.

A simple tab set with 2 tabs would look like:

{tab title="First Tab"}

Some text...

{tab title="Second Tab"}

Some more text...

{/tabs}

This is the result:

Note: Tabs is most stable and reliable if you place each {tab} tag on its own new paragraph line.
