 # Branches
 
-Read through GiLab's branching documentation:
+A branch is a version of a project's working tree. You create a branch for each
+set of related changes you make. This keeps each set of changes separate from
+each other, allowing changes to be made in parallel, without affecting each
+other.
+
+After pushing your changes to a new branch, you can:
+
+- Create a [merge request](../../merge_requests/index.md)
+- Perform inline code review
+- [Discuss](../../discussions/index.md) your implementation with your team
+- Preview changes submitted to a new branch with [Review Apps](../../../../ci/review_apps/index.md).
+
+With [GitLab Starter](https://about.gitlab.com/pricing/), you can also request
+[approval](../../merge_requests/merge_request_approvals.md) from your managers.

-implementations.
+# Signing commits with GPG
 
 > - [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9546) in GitLab 9.5.
 > - Subkeys support was added in GitLab 10.1.
 
-GitLab can show whether a commit is verified or not when signed with a GPG key.
-All you need to do is upload the public GPG key in your profile settings.
+You can use a GPG key to sign Git commits made in a GitLab repository. Signed
+commits are labeled **Verified** if the identity of the committer can be
+verified. To verify the identity of a committer, GitLab requires their public
+GPG key.
 
-GPG verified tags are not supported yet.

+See the [further reading](#further-reading) section for more details on GPG.
 
 ## How GitLab handles GPG
 
 GitLab uses its own keyring to verify the GPG signature. It does not access any
 public key server.
 
-In order to have a commit verified on GitLab the corresponding public key needs
-to be uploaded to GitLab. For a signature to be verified three conditions need
-to be met:
+For a commit to be verified by GitLab:
 
-1. The public key needs to be added your GitLab account
-1. One of the emails in the GPG key matches a **verified** email address you use in GitLab
-1. The committer's email matches the verified email from the gpg key
+- The committer must have a GPG public/private key pair.
+- The committer's public key must have been uploaded to their GitLab
+  account.
+- One of the emails in the GPG key must match a **verified** email address
+  used by the committer in GitLab.
+- The committer's email address must match the verified email address from the
+  GPG key.
