It would be really handy if the tool was also supporting writing ADR using Asciidoc.
Asciidoc is quite popular too, and has interesting 3rd party tooling for aggregating documentation or publishing documentation to Confluence for example.

So it would be nice if the adr tool would let you chose between Markdown and Asciidoc, while keeping Markdown as default.

haha, welcome to PR

@murdos @phodal I've submit the #55 PR which add support for asciidoc.
Unless I've missed some tests, I think almost all current markdown supported functionalities should work with asciidoc.

You can try it if you want.
