Cargo integration: Cargo integrates with rustdoc through `cargo doc` to generate documentation for a project.
Default visibility: By default, rustdoc generates documentation for public functions.
Markdown input: rustdoc can generate HTML from standalone Markdown files.
Markdown limitation: Cargo does not currently understand standalone Markdown files.
Integration output: Cargo places generated documentation under the project's `target` directory and can include documentation for dependencies.
Online documentation: The Rust tools page says Cargo's doc builder is available locally through `cargo doc` and online for public crates through docs.rs.
Installation: Rust's installation page recommends rustup and provides installation instructions for Windows, macOS, Linux, and other Unix-like systems.

Security support scope: The Rust Security Response Working Group handles vulnerability reports for software maintained and published by the Rust Project; third-party crates are outside its stated scope.

Project governance: The Rust Project says it is composed of many teams and contributors, and that major decisions start with a Request for Comments process open to everyone.
