 The Embassy nRF HAL targets the Nordic Semiconductor nRF family of hardware. The HAL implements both blocking and async APIs
 for many peripherals. The benefit of using the async APIs is that the HAL takes care of waiting for peripherals to

 NOTE: The Embassy HALs can be used both for non-async and async operations. For async, you can choose which runtime you want to use.

+Most peripherals are supported. To check what's available, make sure to pick the MCU you're targeting in the top menu in the [documentation](https://docs.embassy.dev/embassy-nrf).

+For MCUs with TrustZone support, both Secure (S) and Non-Secure (NS) modes are supported. Running in Secure mode
+allows running Rust code without a SPM or TF-M binary, saving flash space and simplifying development.
 
 ## Time driver
 
-If the `time` feature is enabled, the HAL uses the RTC peripheral as a global time driver for [embassy-time](https://crates.io/crates/embassy-time), with a tick rate of 32768 Hz.

 ## Embedded-hal
 
 The `embassy-nrf` HAL implements the traits from [embedded-hal](https://crates.io/crates/embedded-hal) (v0.2 and 1.0) and [embedded-hal-async](https://crates.io/crates/embedded-hal-async), as well as [embedded-io](https://crates.io/crates/embedded-io) and [embedded-io-async](https://crates.io/crates/embedded-io-async).
 
+## Interoperability
+
+This crate can run on any executor.
+
+Optionally, some features requiring [`embassy-time`](https://crates.io/crates/embassy-time) can be activated with the `time` feature. If you enable it,
+you must link an `embassy-time` driver in your project.

 ## EasyDMA considerations
 
 On nRF chips, peripherals can use the so called EasyDMA feature to offload the task of interacting
