 Run linux elf binary (alpine rootfs also supported) on HarmonyOS PC, inspired by [Termony](https://github.com/TermonyHQ/Termony), based on [harmony-qemu](https://github.com/hackeris/harmony-qemu).
 
-Originally for quick verification to integrate qemu-user to [Termony](https://github.com/TermonyHQ/Termony).

 # Usage
 
 - Build and sign hap of Harmonix
-  - or download unsigned hap from [Release page](https://github.com/hackeris/Harmonix/releases) and sign by your self
+  - or download unsigned hap from [Release page](https://github.com/hackeris/Harmonix/releases) and sign the hap by your self
 - Install Harmonix to your HarmonyOS PC
-- Download alpine minimal root filesystem from https://alpinelinux.org/downloads/ (aarch64 or x64)
-- In HiShell, extract rootfs tar.gz file to data directory, for example `/data/storage/el2/base/files/alpine`
-- Run qemu-harmonix-aarch64 to load busybox shell with rootfs and environment variables
-```shell
-cd /data/storage/el2/base/files/alpine
-qemu-harmonix-aarch64 -E PATH=/bin:/usr/bin:/sbin -E HOME=/root -L ./ ./bin/busybox sh -c 'cd ~ && sh'

-cd /
-ls

-apk add gcc

-- `gcc` can compile a `Hello World` to run
+- Open Harmonix or HiShell, and run `harmonix_install_alpine` to install Alpine Linux
+- After Alpine Linux installed, run `harmonix_run_alpine` to start Alpine Linux
+- Run `cd /` cd to `/` and run `ls`, you can see the root changed!
+- Run `uname -a` to display system info.
+
+## x86_64
+
+You can also run Linux program of x86_64 on HarmonyOS PC by qemu-harmonix-x86_64 in Harmonix.
+
+- Download alpine minimal root filesystem from [https://alpinelinux.org/downloads/](https://alpinelinux.org/downloads/), choose "Mini root filesystem" -> "x86_64"  
+- Extract downloaded rootfs tar.gz file to data directory, for example `/data/storage/el2/base/files/alpine_x64`
+- Run qemu-harmonix-x86_64 to load busybox shell with rootfs and environment variables
 ```shell
-gcc hello.c -o hello
-./hello

 ```

+- Run `uname -a` to display system info.
 
-# Problems
+# Features
 
-There may be some problems, such as
+- In Alpine Linux, you can use `apk` to install packages.
+- Install `gcc` and `musl-dev` by `apk add gcc musl-dev`, then you can compile C code and run.
+- Install `python` by `apk add python3`, then you can run python script.
+- Install `openjdk17-jdk` by `apk add openjdk17-jdk`, then you can compile Java code by `javac`.
+- More external programs from packages works.
 
-- Some syscalls may not be relocated to rootfs
-- Path may not be relocated as expected
-- Hard link is not supported now
-- Other problems
