 ## Generic targets
 
-The Releases section provides several generic binaries:
+STM8 eForth provides configurations and binaries for typical STM8S and STM8L devices. The binaries for selected "Low", "Medium" or "High density" can be expected to work for all of the listed packaging and memory specs variants. For details please refer to the `README.md` in the linked configuration folder.
 
-Support for STM8S devices [RM0016](https://www.st.com/resource/en/reference_manual/cd00190271-stm8s-series-and-stm8af-series-8-bit-microcontrollers-stmicroelectronics.pdf) is stable. Automotive grade STM8AF devices are likely to work with one of the configurations. Various STM8 Discovery boards and [breakout boards](https://github.com/TG9541/stm8ef/wiki/Breakout-Boards) for "Low", "Medium", and "High density" devices can be used.

 Of course, it's also possible to use a simulated serial interface instead of the UART. This way the UART can be freed up, e.g. for [MODBUS RTU](https://github.com/TG9540/stm8ef-modbus).
