-Linux release does not include lpac binary, you need to [compile lpac](https://github.com/estkme-group/lpac?tab=readme-ov-file#compile) by yourself. The lpac binary file should be placed in the same directory as the EasyLPAC binary file
+## Linux

+lpac binary search order: First, search in the same directory as EasyLPAC. If not found, use `/usr/bin/lpac`
+
+`EasyLPAC-linux-x86_64-with-lpac.tar.gz` contain prebuilt lpac binary, if you can't run it, you need to install `lpac` by package manager or [compile lpac](https://github.com/estkme-group/lpac?tab=readme-ov-file#compile) by yourself.
