-Known issues
+Security contact information
 ******************************************************************************
 
-Due to limitations in both the IDLE shell and the Jetbrains (Pycharm) shells this progressbar cannot function properly within those.
+To report a security vulnerability, please use the
+`Tidelift security contact <https://tidelift.com/security>`_.
+Tidelift will coordinate the fix and disclosure.

+Known issues
+******************************************************************************
 
+- The Jetbrains (PyCharm, etc) editors work out of the box, but for more advanced features such as the `MultiBar` support you will need to enable the "Enable terminal in output console" checkbox in the Run dialog.
 - The IDLE editor doesn't support these types of progress bars at all: https://bugs.python.org/issue23220
-- The Jetbrains (Pycharm) editors partially work but break with fast output. As a workaround make sure you only write to either `sys.stdout` (regular print) or `sys.stderr` at the same time. If you do plan to use both, make sure you wait about ~200 milliseconds for the next output or it will break regularly. Linked issue: https://github.com/WoLpH/python-progressbar/issues/115
 - Jupyter notebooks buffer `sys.stdout` which can cause mixed output. This issue can be resolved easily using: `import sys; sys.stdout.flush()`. Linked issue: https://github.com/WoLpH/python-progressbar/issues/173
