+# OpenIsle Code of Conduct
+
+Like the technical community as a whole, the OpenIsle team and community is made up of a mixture of professionals and volunteers from all over the world, working on every aspect of the mission - including mentorship, teaching, and connecting people.
+
+Diversity is one of our huge strengths, but it can also lead to communication issues and unhappiness. To that end, we have a few ground rules that we ask people to adhere to. This code applies equally to founders, mentors and those seeking help and guidance.
+
+This isn’t an exhaustive list of things that you can’t do. Rather, take it in the spirit in which it’s intended - a guide to make it easier to enrich all of us and the technical communities in which we participate.
+
+This code of conduct applies to all spaces managed by the OpenIsle project or . This includes IRC, the mailing lists, the issue tracker, DSF events, and any other forums created by the project team which the community uses for communication. In addition, violations of this code outside these spaces may affect a person's ability to participate within them.
+
+If you believe someone is violating the code of conduct, we ask that you report it by emailing [](mailto:). For more details please see our 
+
+- **Be friendly and patient.**
+- **Be welcoming.** We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion, and mental and physical ability.
+- **Be considerate.** Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account when making decisions. Remember that we're a world-wide community, so you might not be communicating in someone else's primary language.
+- **Be respectful.** Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one. Members of the OpenIsle community should be respectful when dealing with other members as well as with people outside the OpenIsle community.
+- **Be careful in the words that you choose.** We are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren't acceptable. This includes, but is not limited to: 
+ - Violent threats or language directed against another person.
+ - Discriminatory jokes and language.
+ - Posting sexually explicit or violent material.
+ - Posting (or threatening to post) other people's personally identifying information ("doxing").
+ - Personal insults, especially those using racist or sexist terms.
+ - Unwelcome sexual attention.
+ - Advocating for, or encouraging, any of the above behavior.
+ - Repeated harassment of others. In general, if someone asks you to stop, then stop.
+- **When we disagree, try to understand why.** Disagreements, both social and technical, happen all the time and OpenIsle is no exception. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of OpenIsle comes from its varied community, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.

-> Step1 先克隆仓库
+先克隆仓库：
 
 ```shell
 git clone https://github.com/nagisa77/OpenIsle.git
 cd OpenIsle
 ```
 
-> Step2 后端部署
+- 后端开发环境
+    - JDK 17+
+- 前端开发环境
+    - Node.JS 20+
+
+## 启动后端服务
+
+启动后端服务有多种方式，选择一种即可。
+
+> [!IMPORTANT]
+> 仅想修改前端的朋友可不用部署后端服务。转到 [启动前端服务](#启动前端服务) 章节。
+
+### 本地 IDEA
 
 ```shell
-cd backend
+cd backend/
 ```
 
-以IDEA编辑器为例，IDEA打开backend文件夹。
+IDEA 打开 `backend/` 文件夹。
 
-- 设置VM Option，最好运行在其他端口，非8080，这里设置8081
+#### 配置环境变量
+
+1. 生成环境变量文件
+
+    ```shell
+    cp open-isle.env.example open-isle.env
+    ```
+
+    `open-isle.env.example` 是环境变量模板，`open-isle.env` 才是真正读取的内容
+
+2. 修改环境变量，留下需要的，比如你要开发 Google 登录业务，就需要谷歌相关的变量，数据库是一定要的
+
+    ![环境变量](assets/contributing/backend_img_7.png)
+
+3. 应用环境文件，选择刚刚的 `open-isle.env`
+
+可以在 `open-isle.env` 按需填写个性化的配置，该文件不会被 Git 追踪。比如你想把服务跑在 `8082`（默认为 `8080`），那么直接改 `open-isle.env` 即可：
+
+```ini
+SERVER_PORT=8082
+```
+
+另一种方式是修改 `.properities` 文件（但不建议），位于 `src/main/application.properties`，该配置同样来源于 `open-isle.env`，但修改 `.properties` 文件会被 Git 追踪。
+
+![配置数据库](assets/contributing/backend_img_5.png)
+
+#### 配置 IDEA 参数
+
+- 设置 JDK 版本为 java 17
+- 设置 VM Option，最好运行在其他端口，非 `8080`，这里设置 `8081`
+
+    ```shell
+    -Dserver.port=8081
+    ```
+
+![配置1](assets/contributing/backend_img_3.png)
+
+![配置2](assets/contributing/backend_img_2.png)
+
+#### 配置 MySQL
+
+> [!TIP]
+> 如果不知道怎么配置数据库可以参考 [Docker 环境](#docker-环境) 章节
+
+1. 本机配置 MySQL 服务（网上很多教程，忽略）
+
+    + 可以用 Laragon，自带 MySQL 包括 Nodejs，版本建议 `6.x`，`7` 以后需要 Lisence
+    + [下载地址](https://github.com/leokhoa/laragon/releases)
+
+2. 填写环境变量
+
+    ![环境变量](assets/contributing/backend_img_6.png)
+
+    ```ini
+    MYSQL_URL=jdbc:mysql://<数据库地址>:<端口>/<数据库名>?useUnicode=yes&characterEncoding=UTF-8&useInformationSchema=true&useSSL=false&serverTimezone=UTC
+    MYSQL_USER=<数据库用户名>
+    MYSQL_PASSWORD=<数据库密码>
+    ```
+
+3. 执行 [`db/init/init_script.sql`](backend/src/main/resources/db/init/init_script.sql) 脚本，导入基本的数据
+
+    ![初始化脚本](assets/contributing/resources_img.png)
+
+4. 处理完环境问题直接跑起来就能通了
+
+    ![运行画面](assets/contributing/backend_img_4.png)

+### Docker 环境
+#### 配置环境变量

--Dserver.port=8081
+cd docker/
 ```

+主要配置两个 `.env` 文件
 
-- 设置jdk版本为java 17
+- `backend/open-isle.env`：后端环境变量，配置同上，见 [配置环境变量](#配置环境变量)。
+- `docker/.env`：Docker Compose 环境变量，主要配置 MySQL 相关
+    ```shell
+    cp .env.example .env
+    ```

+> [!TIP]
+> 使用单独的 `.env` 文件是为了兼容线上环境或已启用 MySQL 服务的情况，如果只是想快速体验或者启动统一的环境，则推荐使用本方式。
 
-- 本机配置MySQL服务（网上很多教程，忽略）
-- 设置环境变量.env 文件 或.properties 文件（二选一）
+在指定 `docker/.env` 后，`backend/open-isle.env` 中以下配置会被覆盖，这样就确保使用了同一份配置。
