+
+## Available External Tools
+UTOL allows you to use the following external tool integrations:
+- Zoom: You can integrate Zoom meetings with course participants. For more details, please refer to "[Using Zoom meetings from UTOL via LTI integration (for Course Instructors / TAs)](./zoom/)".
+
+- Slack: You can create a Slack workspace for course participants. For more details, please refer to "[Using UTokyo Slack Workspace from UTOL via Slack Integration (for Course Instructors / TAs)](./slack/)".
+
+- MATLAB Grader: You can assign quizzes created in MATLAB Grader to course participants. For more details, please refer to "[Using MATLAB Grader in UTOL (for Course Instructors / TAs)](./matlab_grader/)".

+## Requesting Additional External Tools
+If you have a license for an LTI v1.3-compatible external tool that is not currently available in UTOL, and are considering using it through integration with UTOL, please contact the UTOL Team (`lms-support@itc.u-tokyo.ac.jp`). When contacting the team, please provide information about the tool and its license, as well as the scope of use (e.g., limited to a specific faculty or course, or available for university-wide use).
