+gitの差分を持つファイルの一覧を取得するためのツールです。
+
+## CLI
+
+```sh
+# HEADからタグが付いているコミットまでの差分を取得する場合
+npx @d-zero/git-diff
+
+# HEADから特定のコミットまでの差分を取得する場合
+npx @d-zero/git-diff <commit-hash>
+
+# 特定のコミットから特定のコミットまでの差分を取得する場合
+npx @d-zero/git-diff <commit-hash> <commit-hash>
+```
+
+差分を取得したいローカルリポジトリに移動し、上記コマンドを入力してください。  
+コミットのハッシュ値を指定する場合、古い方のコミットを先に入力してください
