Important note about running Markdown with other input filters

Markdown may conflict with other input filters, depending on the order
in which filters are configured to apply. If using Markdown produces
unexpected markup when configured with other filters, experimenting with
the order of those filters will likely resolve the issue.

The "Limit allowed HTML tags" filter is a special case:

For best security, ensure that it is run after the Markdown filter and
that only markup you would like to allow in via HTML and/or Markdown is
configured to be allowed via the it.

If you on the other hand want to make sure that all converted Markdown
text is perserved, run it after the Markdown filter. Note that
blockquoting with Markdown doesn't work when run after "Limit allowed
HTML tags". It converts the ">".
