How to develop on a branch in HG?

Question

I would like to do some experimental work in a hg project. So I would like to create branch, commit to it. And if the experiment works, I can merge it back to main branch.

In git, I can do

$ git branch experimental
$ git checkout experimental
(edit file)
$ git commit -a
$ git checkout master

I've read A Guide to Branching in Mercurial. It said hg branch feature. But what is next? I don't follow.

Answer 1

$ hg branch experimental

(edit file)
$ hg commit
$ hg update default
