+## Adding your app 
+
+You can add your plugin by adding it as `_apps/your-plugin-name.md`
+
+Here are the things you need to include about your plugin:
+
+```
+---
+title: Title of Your App
+description: What your App does
+slug: Shortened version of app name
+screenshots:
+- https://somewebsite.com/your-screenshot.png

+
+## Hosting your app
+
+We will list un-hosted apps on the website to help gain more exposure. We will consider hosting apps on a case by case basis.
+
+When considering hosting new plugins here's what we look for, the app:
+
+- Works (ie it can run without errors and perform some sort of action on GitHub through the API)
+- Does something not already done by an existing probot plugin
+- Has minimal tests
+- Has minimal documentation
+- Is open source 
+- Has a license
+- Has a code of conduct
+- Has someone willing to at least minimally maintain them for the near future
