Does bitbucket have project notes?

[Jukka]

I'd like to know that is there a more private note for other devs than README.md

about the project ? in project level or in repo-level.

Sometimes i'd like to write notes that should not be with the project to web server.

I know that with apache i can deny file read with htaccess, but sometimes the server is nginx and htaccess won't work. Or even with apache that still is a risk.
