 ## Contributing
 
 Before contributing, you'll likely find it helpful to [understand context and general vision/direction](https://github.com/maybe-finance/maybe/wiki).
 
-It's still very early days for this so your mileage will vary here and lots of things will break.
+Once you've done that, please visit our [contributing guide](https://github.com/maybe-finance/maybe/blob/main/CONTRIBUTING.md) to get started!
 
-But almost any contribution will be beneficial at this point. Check the [current Issues](https://github.com/maybe-finance/maybe/issues) to see where you can jump in!
+## Self Hosting
 
-If you've got an improvement, just send in a pull request!
+Our long term goal is to make self-hosting as easy as possible. That said, during these early stages of building the product, we are focusing our efforts on development.
 
-1. Fork it
-2. Create your feature branch (`git checkout -b my-new-feature`)
-3. Commit your changes (`git commit -am 'Add some feature'`)
-4. Push to the branch (`git push origin my-new-feature`)
-5. Create new Pull Request
+We will update this section as we get closer to an initial release.
 
-If you've got feature ideas, simply [open a new issue](https://github.com/maybe-finance/maybe/issues/new)!
+Please see our [guide on self hosting here](https://github.com/maybe-finance/maybe/wiki/Self-Hosting-Setup-Guide).
