Completely agree with Sergey.

but in fact it's Jinja [2], it was agreed to change it [3], no to confuse
the user

[1] - I just uses <% and %> to substitute values. That is not ERB style
template language.
[2] - We are not using Jinja templating (it is just yaml file, not html
template), we are using Jinja placeholder substitution. And in current code
we have a problem with content at first parsed from yaml and that parser
treats { and [ as a start if a dict or an array.
[3] - Templates are for people who do not care about Jinja/ERB (maybe some
familiar with Puppet/Chef), so no confusion.
