# Using Vale to improve documentation ###### tags: `Documentation` You can use vale and the Red Hat vale extension to improve your rst or md documentation. This tool gives you recommendations on improving your documentation file, in the form of errors, warnings, and infos. The Red Hat configuration is specific to Red Hat writing style, but there are multiple configurations available or you can customize your own. 1. Install the [vale cli](https://vale.sh/docs/vale-cli/installation/). 2. Configure vale to use the [vale-at-red-hat](https://redhat-documentation.github.io/vale-at-red-hat/docs/user-guide/installing-vale-cli/) Vale configuration. 3. Optionally, add [vale to your IDE](https://redhat-documentation.github.io/vale-at-red-hat/docs/user-guide/using-vale-in-the-ide/). See [Vale for Writers at Red Hat](https://redhat-documentation.github.io/vale-at-red-hat/docs/user-guide/introduction/) for details.
