[🔗](https://github.com/lessthanseventy/excessibility/blob/v0.18.1/lib/mix/tasks/install.ex#L1)

Installs Excessibility into a host project using Igniter.

This task can be invoked directly or via `mix igniter.install excessibility`. It adds the
recommended configuration to the target project's `config/test.exs` and (by default) runs
`npm install` inside the vendored Excessibility assets directory to fetch axe-core dependencies.

Requires Igniter to be installed in the host project.

# `claude_md_section`

This section is appended to existing CLAUDE.md files or used as the initial
content when creating a new one during installation.
