-## Dependencies
-+ `k210 board` or `qemu-system-riscv64`
-+ RISC-V Toolchain: [riscv-gnu-toolchain](https://github.com/riscv/riscv-gnu-toolchain.git)
-
-## Installation
-```bash
-git clone https://github.com/HUST-OS/xv6-k210
-```
-
-## Run on k210 board
-First you need to connect your k210 board to your PC.  
-And check the `USB serial port` (In my situation it will be `ttyUSB0`):  
-```bash
-ls /dev/ | grep USB
-```
-Build the kernel and user program:
-
-```bash
-cd xv6-k210
-make build
-```
-Instead of the original file system, xv6-k210 runs with FAT32. You might need an SD card with FAT32 format.  
-Your SD card should NOT keep a partition table. To start `shell` and other user programs, you need to copy them into your SD card.  
-First, connect and mount your SD card (SD card reader required).
-```bash
-ls /dev/ # To check your SD device
-mount <your SD device name> <mount point>
-make sdcard dst="SD card mount point"
-umount <mount point>
-```
-Then, insert the SD card to your k210 board and run:
-```bash
-make run
-```
-Sometimes you should change the `USB serial port`:  
-```bash
-make run k210-serialport=`Your-USB-port`(default by ttyUSB0)
-```
-Ps: Most of the k210-port in Linux is ttyUSB0, if you use Windows or Mac OS, this doc 
-may help you: [maixpy-doc](https://maixpy.sipeed.com/zh/get_started/env_install_driver.html#)  
-
-## Run on qemu-system-riscv64
-First, make sure `qemu-system-riscv64` is installed on your system.  
-Second, make a disk image file with FAT32 file system.
-```bash
-make fs
-```
-It will generate a disk image file `fs.img`, and compile some user programs like `shell` then copy them into the `fs.img`.  
-As long as the `fs.img` exists, you don't need to do this every time before running, unless you want to update it.
-
-Finally, start running.
-```bash
-make run platform=qemu
-```
-
-Ps: Press Ctrl + A then X to quit qemu.
-
-## About shell
-
-The shell commands are user programs, too. Those program should be put in a "/bin" directory in your SD card or the `fs.img`.  
-Now we support a few useful commands, such as `cd`, `ls`, `cat` and so on.
-
-In addition, `shell` supports some shortcut keys as below:
-
-- Ctrl-H -- backspace  
-- Ctrl-U -- kill a line  
-- Ctrl-D -- end of file (EOF)  
-- Ctrl-P -- print process list  
-
-## Add my programs on xv6-k210
-1. Make a new C source file in `xv6-user/` like `myprog.c`, and put your codes;
-2. You can include `user.h` to use the functions declared in it, such as `open`, `gets` and `printf`;
-3. Add a line "`$U/_myprog\`" in `Makefile` as below:
-    ```Makefile
-    UPROGS=\
-        $U/_init\
-        $U/_sh\
-        $U/_cat\
-        ...
-        $U/_myprog\      # Don't ignore the leading '_'
-    ```
-4. Then make:
-    ```bash
-    make userprogs
-    ```
-    Now you might see `_myprog` in `xv6-user/` if no error detected. Finally you need to copy it into your SD (see [here](#run-on-k210-board))
-     or FS image (see [here](#run-on-qemu-system-riscv64)).
