+## Profiles
+
+This Action supports rustup [profiles](https://blog.rust-lang.org/2019/10/15/Rustup-1.20.0.html#profiles),
+which are can be used to speed up the workflow execution by installing the
+minimally required set of components, for example:
+
+```yaml
+- name: Install minimal nightly
+  uses: actions-rs/toolchain@v1
+  with:
+    profile: minimal
+    toolchain: nightly
+```
+
+This Action will automatically run `rustup self update` if `profile` input is set
+and the installed `rustup` version does not supports them.
+
+In order to provide backwards compatibility for `v1` version,
+there is no value for `profile` input set by default,
+which means that the `default` profile is used by `rustup`
+(and that includes `rust-docs`, `clippy` and `rustfmt`).\
+You may want to consider using `profile: minimal` to speed up toolchain installation.
 
 ## Components
 
-If you are going to install `clippy`, `rustfmt` or any other [rustup component](https://rust-lang.github.io/rustup-components-history/),
+This Action supports rustup [components](https://blog.rust-lang.org/2019/10/15/Rustup-1.20.0.html#installing-the-latest-compatible-nightly) too,
-it might not be available in latest `nightly` build;
+and in combination with the [profiles](#profiles) input it allows to install only the needed components:
-check out the [`actions-rs/components-nightly`](https://github.com/actions-rs/components-nightly) Action,
+
-which makes this process much easier.
+```yaml
+- name: Install minimal stable with clippy and rustfmt
+  uses: actions-rs/toolchain@v1
+  with:
+    profile: minimal
+    toolchain: nightly
+    components: rustfmt, clippy
+```
+
+As an extra perk, `rustup >= 1.20.0` is able to find the most recent `nightly` toolchain
+with the requested components available; next example is utilizing this feature
+to install the minimal set of `nightly` toolchain components with the `rustfmt` and `clippy` extras:
+
+```yaml
+- name: Install minimal nightly with clippy and rustfmt
+  uses: actions-rs/toolchain@v1
+  with:
+    profile: minimal
+    toolchain: nightly
+    components: rustfmt, clippy
+```
+
+Same to the `profile` input, if the installed `rustup` does not supports "components",
+it will be automatically upgraded by this Action.
