 # Usage
 
-## Linux pcscd
+## Linux dependency
 You need to install `pcscd` and keep its daemon running to access pcsc smart card reader.
 ```bash
 sudo apt install pcscd
 sudo systemctl start pcscd
 ```
 
-## GUI Frontend
+`libpcsclite` is alse needed

 ## Windows
 
+Due to a [bug in asn1c](https://github.com/vlm/asn1c/issues/196), the MinGW version of lpac cannot send notification successfully. Building with Cygwin seems to avoid it.
+
+Windows need prebuilt libcurl.dll, you can replace the download link to newest curl version.
+
+- Build on Windows(Cygwin)
+
+With `gcc-core` `gcc-g++` `make` `cmake` `unzip` `wget` installed
+
+```bash
+git clone --depth=1 https://github.com/estkme-group/lpac
+cd lpac && mkdir build && cd build

+```
+To run it outside Cygwin shell, you need copy `cygwin1.dll` to the program folder to distribute.
