jrnl --tags

jrnl --export markdown
Markdown is a simple markup language that is human readable and can be used to be rendered to other formats (html, pdf). This README for example is formatted in markdown and github makes it look nice.
You can specify the output file of your exported journal using the -o argument:
jrnl --export md -o journal.md

my_entries/
