 **Releases, version numbering and the relation to git branches**
 
 - We follow the semantic version numbering as described [here](https://r-pkgs.org/description.html#version).
-- The commit referred to by `master` (branch tip) must always have a `<major>.<minor>.<patch>` version number in the `DESCRIPTION` file.
+- The commit referred to by `main` (branch tip) must always have a `<major>.<minor>.<patch>` version number in the `DESCRIPTION` file.
 It is the latest released package version.
-  - Subsequent commits on `master` which do not change the package code itself, but only website setup and repo documentation, must inherit the _same_ release version number.

 Non-package commits _may_ follow this route as well: it is safe for all new commits.

+- Other branches than `main` can have various names.
 However, there is always at least one **development branch** whose name begins with `dev`.
 For example: `dev_nextrelease`, `dev_0.4.0`, ...
 It is the collector of new features and bugfixes that will lead to a later release, and its first commit should be to add a dev-suffix (`.9000`) to the current version number (don't increment `<major>.<minor>.<patch>`).
   - Especially when cooperating, it is counteradvised to push directly to this branch; better do so through pull requests from feature branches.
-- Eventually, the development branch's last commit before merging to `master` will be to increment at least one of `<major>`, `<minor>` or `<patch>` and to drop the dev-suffix from the version number (i.e. in the `DESCRIPTION` file).

 Such final commits should happen directly on the development branch.
 No later than that commmit (but it can safely be done earlier), also the `.zenodo.json` metadata file must be updated to the new release version number.

 1. Propose to merge your commits into the base branch: after pushing your branch to GitHub (which you can do repeatedly), this starts with making a **pull request** (PR; actually this is a merge request) and assign at least one reviewer before a merge can be decided.
 At that moment, open online discussion in the repo is possible on your changes (for other open discussion that you want to start, make an _issue_).
 As long as no merge is performed, more commits can be added to this PR with `git push`, e.g. to implement requested changes by others.
