+[project_link](https://github.com/karpathy/llama2.c)
+We can run a small model of Llama 2 by following the steps in the project link documentation.
+
+First, clone the project and switch to the changed project directory:
+```shell
+git clone https://github.com/karpathy/llama2.c.git
+```
+
+Then download the model.bin file and place it in the specified directory:
+```shell
+wget https://karpathy.ai/llama2c/model.bin -P out
+```
+
+Then compile and run:
+```shell
+gcc -O3 -o run run.c -lm
+./run out/model.bin
+```
+
+You can get the following output:

+## llama2.c
+
+[项目链接](https://github.com/karpathy/llama2.c)
+我们可以根据项目链接文档中的步骤来运行一个 Llama 2 的小模型。
+
+首先 clone 该项目，并切换到改项目目录下：
+```shell
+git clone https://github.com/karpathy/llama2.c.git
+```
+
+然后下载 model.bin 文件，并放到指定目录下：
+```shell
+wget https://karpathy.ai/llama2c/model.bin -P out
+```
+
+然后编译并运行：
+```shell
+gcc -O3 -o run run.c -lm
+./run out/model.bin
+```
+
+可以得到如下输出：
