 # Features
 
-`cfdp-rs` supports various runtime environments and is also suitable for `no_std` environments.
+The goal of this library is to be flexible enough to support the use-cases of both on-board
+software and of ground software. It has support to make integration on [std] systems as simple
+as possible, but also has sufficient abstraction to allow for integration on`no_std` environments.
+Currently, the handlers still require the [std] feature until
+[thiserror supports `error_in_core`](https://github.com/dtolnay/thiserror/pull/304).
+
 It is recommended to activate the `alloc` feature at the very least to allow using the primary
 components provided by this crate. These components will only allocate memory at initialization
 time and thus are still viable for systems where run-time allocation is prohibited.
