 # github plugin
 
-This plugin supports working with GitHub from the command line. It provides a few things:
+> [!WARNING]
+> This plugin is deprecated and will be removed in a future release. It supports
+> the legacy [`hub`](https://github.com/mislav/hub) CLI, not the current GitHub
+> CLI. For `gh` completion, use the [`gh` plugin](../gh) instead.
 
-* Sets up the `hub` wrapper and completions for the `git` command if you have [`hub`](https://github.com/github/hub) installed.
-* Completion for the [`github` Ruby gem](https://github.com/defunkt/github-gem).
-* Convenience functions for working with repos and URLs.
+The plugin provides compatibility for existing `hub` users by:
 
-### Functions
+- aliasing `git` to `hub` when `hub` is installed;
+- adding completion for `hub`; and
+- defining convenience functions for creating repositories.
 
-* `empty_gh` - Creates a new empty repo (with a `README.md`) and pushes it to GitHub
-* `new_gh` - Initializes an existing directory as a repo and pushes it to GitHub
-* `exist_gh` - Takes an existing repo and pushes it to GitHub
+## Migrating to GitHub CLI
 
-
-## Installation
-
-[Hub](https://github.com/github/hub) needs to be installed if you want to use it. On OS X with Homebrew, this can be done with `brew install hub`. The `hub` completion definition needs to be added to your `$FPATH` before initializing OMZ.
-
-The [`github` Ruby gem](https://github.com/defunkt/github-gem) needs to be installed if you want to use it.
-
-### Configuration
-
-These settings affect `github`'s behavior.
-
-#### Environment variables
-
-* `$GITHUB_USER`
-* `$GITHUB_PASSWORD`
-
-#### Git configuration options
-
-* `github.user` - GitHub username for repo operations
-
-See `man hub` for more details.
-
-### Homebrew installation note
-
-If you have installed `hub` using Homebrew, its completions may not be on your `$FPATH` if you are using the system `zsh`. Homebrew installs `zsh` completion definitions to `/usr/local/share/zsh/site-functions`, which will be on `$FPATH` for the Homebrew-installed `zsh`, but not for the system `zsh`. If you want it to work with the system `zsh`, add this to your `~/.zshrc` before it sources `oh-my-zsh.sh`.
+Install [GitHub CLI](https://cli.github.com/), replace `github` with `gh` in
+your plugin list, and restart your shell:
 
 ```zsh
-if (( ! ${fpath[(I)/usr/local/share/zsh/site-functions]} )); then
-  FPATH=/usr/local/share/zsh/site-functions:$FPATH
-fi
+plugins=(... gh)
 ```
+
+The `gh` plugin supplies completion for the installed GitHub CLI. It does not
+alias `git`, because `gh` is not a Git wrapper.
+
+The closest replacement for creating a GitHub repository from an existing
+local repository is:
+
+```zsh
+gh repo create --source=. --push
+```
+
+## Deprecated functions
+
+- `empty_gh` - creates a new repository with a `README.md` and pushes it to GitHub
+- `new_gh` - initializes an existing directory and pushes it to GitHub
+- `exist_gh` - pushes an existing Git repository to GitHub
+
+These functions remain available during the deprecation period and require
+`hub`. They will be removed with the plugin.
+
+If you continue using `hub`, see its documentation for authentication and
+configuration details.
