-xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix
-Version 6 (v6).  xv6 loosely follows the structure and style of v6,
-but is implemented for a modern x86-based multiprocessor using ANSI C.
-
-ACKNOWLEDGMENTS
-
-xv6 is inspired by John Lions's Commentary on UNIX 6th Edition (Peer
-to Peer Communications; ISBN: 1-57398-013-7; 1st edition (June 14,
-2000)). See also https://pdos.csail.mit.edu/6.828/, which
-provides pointers to on-line resources for v6.
-
-xv6 borrows code from the following sources:
-    JOS (asm.h, elf.h, mmu.h, bootasm.S, ide.c, console.c, and others)
-    Plan 9 (entryother.S, mp.h, mp.c, lapic.c)
-    FreeBSD (ioapic.c)
-    NetBSD (console.c)
-
-The following people have made contributions: Russ Cox (context switching,
-locking), Cliff Frey (MP), Xiao Yu (MP), Nickolai Zeldovich, and Austin
-Clements.

-ERROR REPORTS

-We switched our focus to xv6 on RISC-V; see the mit-pdos/xv6-riscv.git
-repository on github.com.
-
-BUILDING AND RUNNING XV6
-
-To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run
-"make". On non-x86 or non-ELF machines (like OS X, even on x86), you
-will need to install a cross-compiler gcc suite capable of producing
-x86 ELF binaries (see https://pdos.csail.mit.edu/6.828/).
-Then run "make TOOLPREFIX=i386-jos-elf-". Now install the QEMU PC
-simulator and run "make qemu".
+### linux환경에서 test를 하는 법
+
+1. 터미널에서 다음 명령어를 실행합니다.
+
+    ```bash
+    git clone https://github.com/SSUminiOS/A3teamOS/tree/main 
+    ```
+
+2. 터미널에서 makefile이 있는 디렉토리인 src에 접근을 합니다.
+
+    ```bash
+    cd src
+    ```
+
+3. 터미널에서 명령어로 make qemu-nox를 입력합니다.
+
+    ```bash
+    make qemu-nox
+    ```
+
+4. xv6를 실행 후 slabtest를 입력하여 출력 결과를 확인합니다.
+
+    ```bash
+    slabtest
+    ```

+
+그리고 vscode 좌하단에 ><를 클릭하여 실행 중인 컨테이너에 연결을 누르고 /xv6에 연결
