+## Branch Deploys & Deploy Context
+
+Netlify creates [atomic](https://www.netlify.com/docs/versioning-and-rollbacks/#atomic-deploys), [immutable](https://medium.com/netlify/how-netlifys-deploying-and-routing-infrastructure-works-c90adbde3b8d) deploys with [instant rollbacks](https://www.netlify.com/docs/versioning-and-rollbacks/#rollbacks) to any deployment you've ever made.
+
+Any commits pushed to master will automatically be built and deployed to the production url. If you push a commit to a branch, netlify will create a build preview for that commit and branch.  [Branch deploys](https://www.netlify.com/docs/continuous-deployment/#branches-deploys) can also be deployed to the docgov domain if we [setup a custom subdomain](https://app.netlify.com/sites/open-sourced/settings/domain#branch-subdomains).  For example if you wanted your own site at `kyle.docgov.dev` or `beta.docgov.dev`.  Netlify will also build a [deploy preview for every pull request](https://www.netlify.com/blog/2016/07/20/introducing-deploy-previews-in-netlify/).
