== Progress report ==
=== General ===
 * [Miyo] I introduced about VIS system to Ikeda-san who is a software engineer. Now I'm considering what kind of works should VIS people ask Ikeda-san. According to Tomaru-san who is a boss of Ikeda-san, at first, Ikeda-san decided to prepare the Gitlab repository for KAGRA because KAGRA needs version control system for the userapps files which include core codes of KAGRA. After this preparation, I will ask Ikeda-san to work for some software upgrade in VIS. So, next week I will hold hands-on training about the RTmodel, Guardian, SDF, medm, and so on for Ikeda-san.
