-//! ## Using PWM without superuser privileges (`sudo`)
-//!
-//! As of kernel version 4.14.34, released on April 16 2018, it's possible to
-//! configure your Raspberry Pi to allow non-root access to PWM. 4.14.34 includes
-//! a [patch] that allows `udev` to change file permissions when a
-//! PWM channel is exported. This will let any user that's a member of the `gpio`
-//! group configure PWM without having to use `sudo`.
-//!
-//! The `udev` rules needed to make this work haven't been patched in yet as of
-//! June 2018, but you can easily add them yourself. Make sure you're running
-//! 4.14.34 or later, and append the following snippet to
-//! `/etc/udev/rules.d/99-com.rules`. Reboot the Raspberry Pi afterwards.
-//!
-//! ```text
-//! SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
-//!     chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
-//!     chown -R root:gpio /sys/devices/platform/soc/*.pwm/pwm/pwmchip* &&\
-//!     chmod -R 770 /sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
-//! '"

 //! ## Troubleshooting
 //!
 //! ### Permission denied
 //!
-//! If [`new`] returns an `io::ErrorKind::PermissionDenied`
-//! error, make sure `/sys/class/pwm` and all of its subdirectories
-//! are owned by `root:gpio`, the current user is a member of the `gpio` group
-//! and `udev` is properly configured as mentioned above. Alternatively, you can
-//! launch your application using `sudo`.
+//! If [`new`] returns an `io::ErrorKind::PermissionDenied` error, make sure
+//! `/sys/class/pwm` and its subdirectories has the appropriate permissions for the current user.
