 It is a perfect "sidecar" container in Kubernetes - it can periodically pull
 files down from a repository so that an application can consume them.

+git-sync can pull one time, or on a regular interval.  It can pull from the
+HEAD of a branch, from a git tag, or from a specific git hash.  It will only
 re-pull if the target of the run has changed in the upstream repository.  When
 it re-pulls, it updates the destination directory atomically.  In order to do
 this, it uses a git worktree in a subdirectory of the `--root` and flips a
 symlink.
 
-git-sync can also be configured to make webhook call upon sucessful git repo syncronisation. The call is made when right after the symlink is updated.
+git-sync can pull over HTTP(S) (with authentication or not) or SSH.

 ## Webhooks
+
 Webhooks are executed asynchronously from the main git-sync process. If a `webhook-url` is configured,
 when a change occurs to the local git checkout a call is sent using the method defined in `webhook-method`
 (default to `POST`). git-sync will continually attempt this webhook call until it succeeds (based on `webhook-success-status`).
