I'm not sure that's necessary though, given how simple it is (enable share extension, "hg share source dest", repeat).

The ideas are:
  1) have a straightforward from-beginning-to-end overview in committing.rst, followed by a few sections that explain more in detail the most common steps (e.g. how to merge between different versions, how to solve merge conflicts, etc.);
  2) list alternative approaches (e.g. multiple unshared clones) and "advanced" steps (e.g. deal with merge conflicts) in the FAQs;

If you think all the approaches should be listed somewhere, we can always add a new FAQ later, but it shouldn't block this issue (and it shouldn't be in committing.rst).

The point of the share extension is that is no longer necessary to pull/push changesets between clones (the updates still are though).
