Double hash (#) in template

Question

In an Apache Velocity template, double hashtag (i.e. ##) means comment, but I want to add ## literals into the template. How can I do that?

The reason is that I want to make a template for Github wiki, and the template includes h2's

Answer 1

After some research I found this:

#set ( $double_hash = '##' )

${double_hash}

Answer 2

I've even double the stuff in my jira release template that produce markdown...

#set ( $simple_hash = '#' )
#set ( $double_hash = '##' )

Thx for the hint !!
