+        ### General preliminary information
+
+
+        Please keep the following in mind when creating this issue:
+
+
+        1. Fill in as much of the template as possible.
+        2. Provide as much detail as possible. Do not assume other people to know what is going on.
+        3. Keep everything readable and structured. Nobody enjoys reading poorly written reports that are difficult to understand.
+        4. Keep an eye on your report as long as it is open, your involvement might be requested at a later moment.
+        5. Keep the title short and descriptive. The title is not the place to write down a full description of the issue.
+        6. When choosing to omit information in a field, write 'n/a' to explicitly indicate the deliberate absence of data. Avoid leaving the field blank or empty.
