+## Running Flask Applications Under pdb
 
-### Useful Tutorials
+To troubleshoot a Flask application (and any other application running via an
+applicationsserver of sorts), you might need to start the application server under
+the debugger, otherwise, you will get an error like:
+
+```
+BdbQuit
+```
+
+Ideally, you shouldn't need to, as the terminal where you started the
+application server (Flask) should drop you into the debugger automatically.
+
+If you run the application under other application servers like gunicorn, then
+you might need to increase the timeout period to prevent gunicorn from killing
+the process, leading to the error above. Generally speaking, you **SHOULD NOT**
+be running the debugger in production anyway, and therefore you should not need
+to deal with the gunicorn issues.
