  ### Cargo
  +Installation via cargo is done by installing the `bottom` crate:
  +
  ```bash
  # If required, update Rust on the stable channel
  rustup update stable
  cargo install bottom
  -# OR, --locked may be required due to how cargo install works
  +# Alternatively, --locked may be required due to how cargo install works
  cargo install bottom --locked
  ```
