## Wing IDE
- you can optionally pass `target_version=<version>` with the same values as in the
command line.
- `:BlackUpgrade` to upgrade _Black_ inside the virtualenv;
-- `:BlackVersion` to get the current version of _Black_ inside the virtualenv.
+- `:BlackVersion` to get the current version of _Black_ in use.

+#### Installation
+
+This plugin **requires Vim 7.0+ built with Python 3.7+ support**. It needs Python 3.7 to
+be able to run _Black_ inside the Vim process which is much faster than calling an
+external command.
+
+##### `vim-plug`
To install with [vim-plug](https://github.com/junegunn/vim-plug):
+_Black_'s `stable` branch tracks official version updates, and can be used to simply
+follow the most recent stable version.
+
```
Plug 'psf/black', { 'branch': 'stable' }
```
+Another option which is a bit more explicit and offers more control is to use
+`vim-plug`'s `tag` option with a shell wildcard. This will resolve to the latest tag
+which matches the given pattern.
+
+The following matches all stable versions (see the
+[Release Process](../contributing/release_process.md) section for documentation of
+version scheme used by Black):
+
+```
+Plug 'psf/black', { 'tag': '*.*.*' }
+```
+
+and the following demonstrates pinning to a specific year's stable style (2022 in this
+case):
+
+```
+Plug 'psf/black', { 'tag': '22.*.*' }
+```
+
+##### Vundle
+
or with [Vundle](https://github.com/VundleVim/Vundle.vim):
```
$ git checkout origin/stable -b stable
```
+##### Arch Linux
+
+On Arch Linux, the plugin is shipped with the
+[`python-black`](https://archlinux.org/packages/community/any/python-black/) package, so
+you can start using it in Vim after install with no additional setup.
+
+##### Vim 8 Native Plugin Management
+
or you can copy the plugin files from
[plugin/black.vim](https://github.com/psf/black/blob/stable/plugin/black.vim) and
[autoload/black.vim](https://github.com/psf/black/blob/stable/autoload/black.vim).
Let me know if this requires any changes to work with Vim 8's builtin `packadd`, or
Pathogen, and so on.
-This plugin **requires Vim 7.0+ built with Python 3.6+ support**. It needs Python 3.6 to
-be able to run _Black_ inside the Vim process which is much faster than calling an
-external command.
+#### Usage
On first run, the plugin creates its own virtualenv using the right Python version and
automatically installs _Black_. You can upgrade it later by calling `:BlackUpgrade` and
example you want to run a version from main), create a virtualenv manually and point
`g:black_virtualenv` to it. The plugin will use it.
+If you would prefer to use the system installation of _Black_ rather than a virtualenv,
+then add this to your vimrc:
+
+```
+let g:black_use_virtualenv = 0
+```
+
+Note that the `:BlackUpgrade` command is only usable and useful with a virtualenv, so
+when the virtualenv is not in use, `:BlackUpgrade` is disabled. If you need to upgrade
+the system installation of _Black_, then use your system package manager or pip--
+whatever tool you used to install _Black_ originally.
+
To run _Black_ on save, add the following lines to `.vimrc` or `init.vim`:
```
nnoremap <F9> :Black<CR>
```
+#### Troubleshooting
+
**How to get Vim with Python 3.6?** On Ubuntu 17.10 Vim comes with Python 3.6 by
default. On macOS with Homebrew run: `brew install vim`. When building Vim from source,
use: `./configure --enable-python3interp=yes`. There's many guides online how to do
projects / etc / vim.git / blobdiff
