 ## Inputs
 
 * `command` (*required*) - Cargo command to run (ex. `check` or `build`)
-* `toolchain` - Rust toolchain to use (without the `+` sign, ex. `nightly`)
+* `toolchain` - Rust toolchain to use (without the `+` sign, ex. `nightly`);\
+    Override or system toolchain will be used if omitted.
 * `args` - Arguments for the cargo command
 * `use-cross` - Use [`cross`](https://github.com/rust-embedded/cross) instead of `cargo` (default: `false`)
 
-## Why?
+## Virtual environments
 
-Why is it needed when you can just do the `-run: cargo build` step?
+Note that `cargo` is not available by default for all [virtual environments](https://help.github.com/en/articles/software-in-virtual-environments-for-github-actions);
+for example, as for 2019-09-15, `macOS` env is missing it.
 
-Because it can call [cross](https://github.com/rust-embedded/cross) instead of `cargo`
-if needed. If `cross` is not installed, it will be installed automatically on a first call.
+You can use [`actions-rs/toolchain`](https://github.com/actions-rs/toolchain)
+to install the Rust toolchain with `cargo` included.
 
-In a future this Action might be available to install other cargo subcommands on demand too.
+## Cross
+
+In order to make cross-compilation an easy process,
+this Action can install [cross](https://github.com/rust-embedded/cross)
+tool on demand if `use-cross` input is enabled; `cross` executable will be invoked
+then instead of `cargo` automatically.
+
+All consequent calls of this Action in the same job will use the same `cross` installed.
