Don't have to present about a published paper or an official material (e.g. you can present something like your know-how)
Some recommendations
If there are any references or materials (e.g. your own PPT, blog article, or paper link), please list up them in the body of issue before the seminar
Please use labels in github as tags, so we can categorize our materials (and if there is no related label, please make one)
Please open an issue at least a day before the seminar and close the issue after it is presented (if you forget, simply open-and-close an issue after the seminar)
After seminar, it would be perfect if we can share our discussion during the seminar as comments
