Hmm, okay - I’ll try commiting only the _site directory and see if that works.
No particular reason for using Bitbucket instead of github except that I use Bitbucket for my other projects. I just assumed it would be equally possible in Bitbucket, but if it becomes too difficult I’ll switch to GH.
If I commit a Jekyll directory (such as, for example, I can do by doing jekyll new test1) to a github pages repository, then will GH run jekyll every time I commit changes to my files?
