Huh? The "orignal" text/x-markdown file should already exist globally:


also generated from tis file:

but, feel free to do so:
mkdir -p ~/.local/share/mime/text
cp -t ~/.local/share/mime/text /usr/share/mime/text/x-markdown.xml

(view mail as source or plain text if not shown)
<?xml version="1.0" encoding="utf-8"?>
<mime-type xmlns="http://www.freedesktop.org/standards/shared-mime-info" type="text/x-markdown">
   <comment>Markdown document</comment>
   <sub-class-of type="text/plain"/>
   <glob pattern="*.md"/>
   <glob pattern="*.mkd"/>
   <glob pattern="*.markdown"/>
