In a typical research process, different versions of files are created over time and must be documented well and traceably. The open source software GitLab allows hosting and managing Git repositories where code and, beyond that, almost any kind of file can be tracked. In addition, GitLab offers features such as issue tracking, wiki or code review. In this digital workshop, participants will learn the basic use of git and GitLab. Besides executing first commands, participants will get an impression of collaborative work with GitLab. Fdm.nrw and NFDI4Ing offer this training jointly.
