+> Clippy lints in your Pull Requests
+
+This GitHub Action executes [`clippy`](https://github.com/rust-lang/rust-clippy)
+and posts all lints as annotations for the pushed commit.
+
+![Screenshot](./.github/screenshot.png)
+
+## Example workflow
+
+This example is utilizing [`components-nightly`](https://github.com/actions-rs/components-nightly)
+and [`toolchain`](https://github.com/actions-rs/toolchain) Actions
+to install the most recent `nightly` clippy version.
+
+```yaml
+on: push
+name: Clippy check
+jobs:
+  clippy_check:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@1
+      - id: component
+        uses: actions-rs/components-nightly@v1
+        with:
+          component: clippy
+      - uses: actions-rs/toolchain@v1
+        with:
+            toolchain: ${{ steps.component.outputs.toolchain }}
+            override: true
+      - run: rustup component add clippy
+      - uses: actions-rs/clippy-check@v1
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+          args: --all-features
+```
+
+### With stable clippy
+
+```yaml
+on: push
+name: Clippy check
+jobs:
+  clippy_check:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v1
+      - run: rustup component add clippy
+      - uses: actions-rs/clippy-check@v1
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+          args: --all-features
+```
+
+## Inputs
+
+* `token` (*required*): GitHub secret token
+* `toolchain` - Rust toolchain to use (without the `+` sign, ex. `nightly`);\
+    Override or system default toolchain will be used if omitted.
+* `args` - Arguments for the `cargo clippy` command
+* `use-cross` - Use [`cross`](https://github.com/rust-embedded/cross) instead of `cargo` (default: `false`)
+
+For extra details about the `toolchain`, `args` and `use-cross` inputs,
+see [`cargo` Action](https://github.com/actions-rs/cargo#inputs) documentation.
