-Installing on Windows is not supported because we use symlinks inside Python
-packages.
+Install Ansible-lint to apply rules and follow best practices with your automation content.
 
-Our project does not ship a container. Please avoid raising any bugs
-related to containers and use the [discussions](https://github.com/ansible/ansible-lint/discussions) forum instead.
+```{note}
+Ansible-lint does not currently support installation on Windows systems.
+```
+
+For a container image, we recommend using [creator-ee](https://github.com/ansible/creator-ee/), which includes Ansible-lint.
+If you have a use case that the `creator-ee` container does satisfy, please contact the team through the [discussions](https://github.com/ansible/ansible-lint/discussions) forum.
 
-We recommend you to try [creator-ee](https://github.com/ansible/creator-ee/),
-which is a container that also carries ansible-lint.
+You can also run Ansible-lint on your source code with the [Ansible-lint GitHub action](https://github.com/marketplace/actions/ansible-lint) instead of installing it directly.
 
-## Using pip or pipx
+## Installing the latest version
 
-You can use either [pip3] or [pipx] to install it; the latter one
-automatically isolates the linter from your current python environment.
-That approach may avoid having to deal with particularities of installing
-python packages, like creating a virtual environment, activating it, installing
-using `--user` or fixing potential conflicts if not using virtualenvs.
+You can install the most recent version of Ansible-lint with the [pip3] or [pipx] Python package manager.
+Use [pipx] to isolate Ansible-lint from your current Python environment as an alternative to creating a virtual environment.
 
 ```bash
-# This will also install ansible-core if needed
+# This also installs ansible-core if it is not already installed
 pip3 install "ansible-lint"
 ```

+# This also installs ansible-core if it is not already installed
+dnf install "ansible-lint"
