+.SYNOPSIS
+    Bumps package versions, generates changelog, creates a release branch, and opens a PR.
+
+.DESCRIPTION
+    This script automates the SDK release kickoff process:
+    1. Bumps the version in eng/targets/Release.props based on the bump type or explicit version.
+    2. Runs generate_changelog.py to produce a changelog entry.
+    3. Prepends the generated changelog entry to CHANGELOG.md.
+    4. Creates a release branch and pushes it.
+    5. Opens a pull request targeting main.
+
+.PARAMETER BumpType
+    The type of version bump: 'major', 'minor', 'patch', or 'explicit'.
+
+.PARAMETER ExplicitVersion
+    The explicit version to set (required when BumpType is 'explicit'). Format: 'X.Y.Z'.
+
+.PARAMETER VersionSuffix
+    Optional pre-release suffix (e.g., 'preview', 'rc.1'). Leave empty for stable releases.
