A few things you should know

Ghost is designed for ambitious, professional publishers who want to actively build a business around their content. That's who it works best for.
The entire platform can be modified and customised to suit your needs. It's very powerful, but does require some knowledge of code. Ghost is not necessarily a good platform for beginners or people who just want a simple personal blog.
It's possible to work with all your favourite tools and apps with hundreds of integrations to speed up your workflows, connect email lists, build communities and much more.

Behind the scenes

Ghost is made by an independent non-profit organisation called the Ghost Foundation. We are 100% self funded by revenue from our Ghost(Pro) service, and every penny we make is re-invested into funding further development of free, open source technology for modern publishing.

The version of Ghost you are looking at right now would not have been made possible without generous contributions from the open source community.

Next up, the editor

The main thing you'll want to read about next is probably: the Ghost editor. This is where the good stuff happens.

By the way, once you're done reading, you can simply delete the default Ghost user from your team to remove all of these introductory posts!
