 # EduSystem
 
+### 使用手册
+
+1. 创建数据库
+
+   ```sql
+   create database edu_sys;
+   ```
+
+2. 修改`EduSystemServer/setting.py`文件中的配置
+
+   ```python
+   DATABASES = {
+       'default': {
+           'ENGINE': 'django.db.backends.mysql',
+           'NAME': "edu_sys",
+           'USER': "用户名",
+           'PASSWORD': "密码",
+           'HOST': "localhost",
+           'PORT': 3306,
+       }
+   }
+   ```
+
+3. 迁移模型至数据库
+
+   1. 生成迁移文件
+
+      ```shell
+      python manage.py makemigrations Eduadmin
+      python manage.py makemigrations Student
+      python manage.py makemigrations teacher
+      python manage.py makemigrations course
+      ```
+
+   2. 迁移
+
+      ```python
+      python manage.py migrate
+      ```
+
+4. 创建admin用户
+
+   ```python
+   python manage.py createsuperuser
+   # 输入用户名，邮箱，密码
+   ```
+
+5. 运行程序
+
+   ```python
+   python manage.py runserver
+   ```
+
