 At some point the driver will hopefully be added to official release of CHIRP.
 
-Currently you can use modified version of CHIRP from [releases](https://github.com/egzumer/uvk5-chirp-driver/releases). You can also use development version of driver [uvk5_EGZUMER.py](uvk5_EGZUMER.py?raw=1) and load it to CHIRP manually.
+Currently you can use modified version of CHIRP from [releases](https://github.com/egzumer/uvk5-chirp-driver/releases). The modified CHIRP is built from [source code](https://github.com/egzumer/chirp/tree/egzumer) and contains the driver. It is packed using pyinstaller into one file for convinience, however some antiviruses don't like that and [report it as a threat](https://stackoverflow.com/questions/43777106/program-made-with-pyinstaller-now-seen-as-a-trojan-horse-by-avg). If you don't trust this file, then use the other method.

+# Custom firmware build options
+
+This driver supports custom Egzumer firmware builds and detects which [options](https://github.com/egzumer/uv-k5-firmware-custom?tab=readme-ov-file#user-customization) have been used.
+Disabled options will be hidden in CHIRP. This only works if the configuration was read from a specific radio. You can use configuration files from other radios with different build options, but unsupported settings will be reset to defaults on the target radio.
