+|===
+
+The Git Commit "source" returns the latest commit hash referenced by a Git branch.
+
+The Git Commit "condition" checks that a commit exists in a repository.
+The commit hash defaults to the source output and can be overridden with `spec.hash`.
+Abbreviated hashes are supported.
+
+The target stage is not supported because commit hashes are immutable values.
+
+== Repository selection
+
+Both the source and the condition select a repository in the following order:
+
+. The repository configured by `spec.url` is cloned.
+. Otherwise, `spec.path` selects an existing local repository.
+. Otherwise, the working directory from `scmid` is used.
+
+When `spec.branch` is omitted, the current `HEAD` commit is returned.
+When it is set, Updatecli resolves the local branch first and then its `origin` remote-tracking branch.
+The lookup does not check out the branch or modify the working tree.
+
+== Parameters
+
+{{< resourceparameters "sources" "gitcommit" >}}
+
+[NOTE]
+====
+YAML parses an unquoted all-digit value as a number.
+Quote `spec.hash` when the commit hash only contains digits.
+====
+
+== Example
+
+The following manifest shows SCM, URL, and local-path inputs.
