+Please note, this package is about IMPLEMENTATION of CommonMark https://commonmark.org/, and adherence to he upstream markdown-it package,
+not about markdown itself. We stay aside of markup discussions. Prior to report a bug, make sure it's about this package, not generic thing.
+
+**Before you post**
+
+1. https://spec.commonmark.org/ - make sure you've read CommonMark spec.
+2. https://spec.commonmark.org/dingus/ - if you think you found parse error, check it in reference implementation first.
+3. https://markdown-it.github.io/ to test what is the expected output from markdown-ot
+
+**In your report**
+
+It will be very helpful, if you can provide permalinks with online samples and explain the difference:
+
+- https://markdown-it.github.io/ - online demo of `markdown-it`.
+- https://spec.commonmark.org/dingus/ - online demo of reference CommonMark's implementation.
+
+If you wish to provide code sample - make sure it is as small as possible and can be executed.
