I'm a new Mercurial user hoping to use your (great!) service to collaborate with colleagues. I began a mercurial repo on my machine and hoped to sync it with your online service using the very clearly-written wizard (specifically, the "Import an existing repository" link).
The whole process went very well but I was unable to determine how to BitBucket my default repository. While your site clearly recommends editing my $REPO/.hg/hgrc file to make BitBucket the default repo, it does not mention the exact changes I would need to make to this file. I would (humbly) suggest adding the text of this edit (added below) to your "Import an existing repository" page.
[paths] default = https://email@example.com/user/repo_name
Many many thanks, Edward
