chore(docs/writer): fix Windows path incompatibilities

NodeJS on Windows uses back slashes for path separators. This
difference can be mitigated by use of the nodeJS path library.
In particular the `sep` property and the `dirname()`, `normalize()`
and `join()` methods of this library.  All path based arguments on
exported functions need to be normalized and `join` and `sep` must
be used instead of string manipulation to work with paths.
docs(guide/bootstrap): clarify manual bootstrapping
