+# Welcome to Sourcegraph
+This is a compilation of the most important information you will need to get started.
+
+
+## 🔄 Sync Code Hosts
+
+Sourcegraph is nothing without your code, so connecting your code hosts is crucial. 
+
+How to connect to…
+- [GitHub](https://docs.sourcegraph.com/admin/external_service/github)
+- [GitLab](https://docs.sourcegraph.com/admin/external_service/gitlab)
+- [Bitbucket Cloud](https://docs.sourcegraph.com/admin/external_service/bitbucket_cloud)
+- [Bitbucket Server / Bitbucket Data Center](https://docs.sourcegraph.com/admin/external_service/bitbucket_server)
+- [Other Git code hosts (using a Git URL)](https://docs.sourcegraph.com/admin/external_service/other)
+- [Non git hosts](https://docs.sourcegraph.com/admin/external_service)
+
+
+## 👥 Inviting users and SSO
+
+A team is essential when using Sourcegraph. Be sure to spread the word and get everybody in.
+
+
+#### Setting up SSO
+
+Sourcegraph supports out-of-the-box support for different auth providers. Our documentation provides guidance on how to setup these.
+
+- [User authentication (SSO) - Sourcegraph docs](https://docs.sourcegraph.com/admin/auth)
+
+You may not have the right privileges or role in your team to set this up. In that case, you could invite someone with the right privileges and make them a site-admin.
+
+
+#### Inviting Single Users
+
+Getting users into Sourcegraph is easy, you just need to navigate to:
+
+**Site Admin** → **Users and auth** → **Users** → **+ Create user**
+
+
+
+## ✉️ Setup Email Server
+
+By default the Sourcegraph instance cannot send emails. So features like password resets, email invites and email code monitors will not work.
+- [Configure email sending / SMTP server](https://docs.sourcegraph.com/admin/config/email)
+
+
+## 🎓 Learn Sourcegraph
