---@return type {description}
```
- If possible, add type information (`table`, `string`, `number`, ...). Multiple valid types are separated by a bar (`string|table`). Indicate optional parameters via `type|nil`.
- If a function in your Lua module should _not_ be documented (e.g. internal or local function), set the doc comment to:
```
---@private
```
- Mark deprecated functions with:
```
---@deprecated
```
- If a function in your Lua module should _not_ be documented, add `@nodoc`.
- If the function is internal or otherwise non-public add `@private`.
- Private functions usually should be underscore-prefixed (named "_foo", not "foo").
- Mark deprecated functions with `@deprecated`.

Automation (CI)
---------------
Our CI and automation jobs are primarily driven by GitHub Actions. Guidelines:
### Backup
### General
Discussions from issues and PRs are backed up here:
https://github.com/neovim/neovim-backup
### Development guidelines
* CI and automation jobs are primarily driven by GitHub Actions.
* Avoid macOS if an Ubuntu or a Windows runner can be used instead. This is
because macOS runners have [tighter restrictions on the number of concurrent
jobs](https://docs.github.com/en/actions/learn-github-actions/usage-limits-billing-and-administration#usage-limits).
### Runner versions
* For special-purpose jobs where the runner version doesn't really matter,
prefer `-latest` tags so we don't need to manually bump the versions. An
example of a special-purpose workflow is `labeler.yml`.
* For our testing jobs, which are in `test.yml` and `build.yml`, prefer to use
the latest stable (i.e. non-beta) version explicitly. Avoid using the
`-latest` tags here as it makes it difficult to determine from an unrelated
PR if a failure is due to the PR itself or due to GitHub bumping the
`-latest` tag without our knowledge. There's also a high risk that automatic
bumping the CI versions will fail due to manual work being required from
experience.
* For our release job, which is `release.yml`, prefer to use the oldest stable
(i.e. non-deprecated) versions available. The reason is that we're trying to
produce images that work in the broadest number of environments, and
therefore want to use older releases.
