Get Started is a really good resource to learn more about the Blogo interface, how to use images, using the Blogo extension, and much more! So it's not at all bad if you want to check it out again.
You can view this when you first launch Blogo, but it's easily accessible whenever you need it.
1. Open up Blogo.
2. Click on Help in the Menu Bar.
3. In the dropdown menu select "Get Started".
4. Explore and learn!
