# Development The unit tests are the check that the directory exchange, the journal, and the command line keep the behaviour described in {doc}`../topics/staging`. The design audit against the staged-rebuild notes is the included {doc}`../reference/design`. Org-mode sources remain in the tree for readers who edit them directly: * `docs/orgmode/howto/staged-rebuild.org` * `docs/orgmode/reference/staged-rebuild.org` * `docs/orgmode/reference/audit.org` The HTML site is the guide those files point at for the operator steps. ```{toctree} :maxdepth: 1 testing ```
