 # It prints information about breaking-changes first and the rest.
 # The content is mostly based on `git log --oneline --since 202X-YY-ZZ`.
 
-# Usage: the script takes one command-line argument that will be used on '-since' option of git command.
-# As an example, you can run a script with a following command, and it will print commit titles between today and 2024-07-01.
-# ```
-# docs/scripts/release-note.sh 2024-07-01
-# ```
+# Usage: the script takes command-line arguments to specify the range of commits to include.
+# You can use either:
+# 1. Date-based range with --since: docs/scripts/release-note.sh --since 2025-08-06
+# 2. Hash-based range with --previous-hash: docs/scripts/release-note.sh --previous-hash abc123
+# 3. Legacy positional argument (deprecated): docs/scripts/release-note.sh 2024-07-01
 
 # This script is supposed to work on all Windows based shell systems including WSL and git-bash.
 # If you make any modifications, please test them, because CI doesn't test this script.
