+To add a problem, create the necessary files. Pick an unused problem ID from
+the relevant range below:
+
+    Prolog: 10000-19999
+    Python: 20000-29999
+    Robot:  30000-39999
+
+Running scripts/build_web_resources.py in the codeq-server repo will generate
+JSON files for all problems, and insert new problems, groups and languages in
+the database.
