Rails何时生成readme.md（而不是readme.rdoc）？

Question

I noticed that when I generate a new rails app sometimes I end up with a readme.md and sometimes with a readme.rdoc (which Bitbucket doesnt automatically render apparentely).

If you've got any ideas about that, please let me know.

Answer 1

Running rails new with Rails 4 (or Rails 3 ) generates README.rdoc , while running it with Rails 5 creates README.md .

This is listed in the notable changes section of the Rails 5.0 release notes:

• Newly generated applications and plugins get a README.md in Markdown. ( commit , Pull Request )
