Worked even a single day that week? Report what you did on those days. If you did not work at all that week, do not fill the form in β skip it entirely.
Pick an existing project whenever one fits. If something comes back every week, ask an admin to add it as a permanent project instead of typing it in by hand each time.
Don't report time off here. Vacation, public holidays and sick leave do not belong in this form.
Don't invent one-off labels like "Integracja" or "WdroΕΌenia" β report that time under the project it was done for.
One-off work only. If it repeats week after week, ask an admin to add it as a real project.
