-#### `proselint`
-
-`proselint` checks for common problems with English prose. It provides a
- [plethora of checks](http://proselint.com/checks/) that are helpful for technical writing.
-
-`proselint` can be used [on the command line](http://proselint.com/utility/), either on a single
- Markdown file or on all Markdown files in a project. For example, to run `proselint` on all
- documentation in the [`gitlab` project](https://gitlab.com/gitlab-org/gitlab), run the
- following commands from within the `gitlab` project:
-
-```shell
-cd doc
-proselint **/*.md
-```
-
-`proselint` can also be run from within editors using plugins. For example, the following plugins
- are available:
-
-- [Sublime Text](https://packagecontrol.io/packages/SublimeLinter-contrib-proselint)
-- [Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=PatrykPeszko.vscode-proselint)
-- [Others](https://github.com/amperser/proselint#plugins-for-other-software)

-##### Sample `proselint` configuration

-    "typography.symbols": false,
-    "misc.phrasal_adjectives": false
