+# Install Rust Toolchain
+
+This GitHub Action installs a Rust toolchain using rustup. It is designed for
+one-line concise usage and good defaults.
+
+<br>
+
+## Example workflow
+
+```yaml
+name: test suite
+on: [push, pull_request]
+
+jobs:
+  test:
+    name: cargo test
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: dtolnay/rust-toolchain@stable
+      - run: cargo test --all-features
+```
+
+The selection of Rust toolchain is made based on the particular @rev of this
+Action being requested. For example "dtolnay/rust-toolchain@nightly" pulls in
+the nightly Rust toolchain, while "dtolnay/rust-toolchain@1.42.0" pulls in
+1.42.0.
+
+<br>
+
+## Inputs
+
+All inputs are optional.
+
+<table>
+<tr>
+  <th>Name</th>
+  <th>Description</th>
+</tr>
+<tr>
+  <td><code>toolchain</code></td>
+  <td>
+    Rustup toolchain specifier e.g. <code>stable</code>, <code>nightly</code>, <code>1.42.0</code>, <code>nightly-2022-01-01</code>.
+    <b>Important: the default is to match the @rev as described above.</b>
+    When passing an explicit <code>toolchain</code> as an input instead of @rev, you'll want to use "dtolnay/rust-toolchain@master" as the revision of the action.
+  </td>
+</tr>
+<tr>
+  <td><code>targets</code></td>
+  <td>Comma-separated string of additional targets to install e.g. <code>wasm32-unknown-unknown</code></td>
+</tr>
+<tr>
+  <td><code>components</code></td>
+  <td>Comma-separated string of additional components to install e.g. <code>clippy, rustfmt</code></td>
+</tr>
+</table>
+
+<br>
+
+## Outputs
+
+<table>
+<tr>
+  <th>Name</th>
+  <th>Description</th>
+</tr>
+<tr>
+  <td><code>cachekey</code></td>
+  <td>A short hash of the installed rustc version, appropriate for use as a cache key. <code>"20220627a831"</code></td>
+</tr>
+<tr>
+  <td><code>name</code></td>
+  <td>Rustup's name for the selected version of the toolchain, like <code>"1.62.0"</code>. Suitable for use with <code>cargo +${{steps.toolchain.outputs.name}}</code>.</td>
+</tr>
+</table>
+
+<br>
+
+## Toolchain expressions
+
+The following forms are available for projects that use a sliding window of
+compiler support.
+
+```yaml
+     # Installs the most recent stable toolchain as of the specified time
+     # offset, which may be written in years, months, weeks, or days.
+  - uses: dtolnay/rust-toolchain@master
+    with:
+      toolchain: stable 18 months ago
+```
+
+```yaml
+     # Installs the stable toolchain which preceded the most recent one by
+     # the specified number of minor versions.
+  - uses: dtolnay/rust-toolchain@master
+    with:
+      toolchain: stable minus 8 releases
+```
