+This is a dummy crate to publish to crates.io. It primarily exists to ensure that folks trying to install clippy from crates.io get redirected to the `rustup` technique.
+
+Before publishing, be sure to rename `clippy_dummy` to `clippy` in `Cargo.toml`, it has a different name to avoid workspace issues.

+Installing clippy via crates.io is deprecated. Please use the following:
+
+```terminal
+rustup component add clippy-preview
+```
+
+on a Rust version 1.29 or later. You may need to run `rustup self update` if it complains about a missing clippy binary.
