-# 一 简介
+# 简介
 
 在 openEuler 发行版开发过程，需要及时更新上游社区各个软件包的最新代码，修改功能 bug 及安全问题，确保发布的 openEuler 发行版尽可能避免缺陷和漏洞。
 
 本工具对软件包进行补丁管理，主动监控上游社区提交，自动生成补丁，并自动提交 issue 给对应的 maintainer，同时自动验证补丁基础功能，减少验证工作量支持 maintainer 快速决策。
 
-# 二 架构
+# 架构
 
-### 2.1 CS架构
+## C/S架构
 
-补丁跟踪采用 C/S 架构，其中服务端(patch-tracking) 负责执行补丁跟踪任务，包括：维护跟踪项，识别上游仓库分支代码变更并形成补丁文件，向 Gitee 提交 issue 及 PR，同时 patch-tracking 提供 RESTful 接口，用于对跟踪项进行增删改查操作。客户端，即命令行工具（patch-tracking-cli），通过调用 patch-tracking 的 RESTful 接口，实现对跟踪项的增删改查操作。

+
+## 核心流程
 
 * 补丁跟踪服务流程
 
 **主要步骤：**
+
 1. 命令行工具写入跟踪项。
 2. 自动从跟踪项配置的上游仓库（例如Github）获取补丁文件。
 3. 创建临时分支，将获取到的补丁文件提交到临时分支。

+将生成的 `self-signed.key` 和 `self-signed.crt` 文件拷贝到 __/etc/patch-tracking__ 目录
 
 
-### 3.4 配置
+##  配置参数
 
-在配置文件中进行对应参数的配置。
+在配置文件中对相应参数进行配置，配置文件路径为 `/etc/patch-tracking/settings.conf`。
 
-配置文件路径 `/etc/patch-tracking/settings.conf`。
+1. 配置服务监听地址。
 
+    ```
+    LISTEN = "127.0.0.1:5001"
+    ```
 
-- 服务监听地址
+2. GitHub Token， 用于访问托管在 GitHub 上游开源软件仓的仓库信息 ， 生成 GitHub Token 的方法参考 [Creating a personal access token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) 。
 
-```python
-LISTEN = "127.0.0.1:5001"
-```
+    ```
+    GITHUB_ACCESS_TOKEN = ""
+    ```
 
-- GitHub Token，用于访问托管在 GitHub 上游开源软件仓的仓库信息
+3. 对于托管在gitee上的需要跟踪的仓库，配置一个有该仓库权限的gitee的token，用于提交patch文件，提交issue，提交PR等操作。
 
-生成 GitHub Token 的方法参考 [Creating a personal access token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
+    ```
+    GITEE_ACCESS_TOKEN = ""
+    ```
 
-```python
-GITHUB_ACCESS_TOKEN = ""
-```
+4. 定时扫描数据库中是否有新增或修改的跟踪项，对扫描到的跟踪项执行获取上游补丁任务，在这里配置扫描的时间间隔，数字单位是秒。
 
-- 对于托管在gitee上的需要跟踪的仓库，配置一个有该仓库权限的gitee的token，用于提交patch文件，提交issue，提交PR等操作。
+    ```
+    SCAN_DB_INTERVAL = 3600
+    ```
 
-```python
-GITEE_ACCESS_TOKEN = ""

+    ```
+    USER = "admin"

->* 长度大于等于6个字符
->* 至少有一个数字
->* 至少有一个大写字母
->* 至少有一个小写字母
->* 至少有一个特殊字符 (~!@#%^*_+=-)
-
-需要将口令的哈希值通过命令工具生成后将其配置到此处，获取方法为执行命令`generate_password <password>`，例如：
-
-    [root]# generate_password Test@123
-    pbkdf2:sha256:150000$w38eLeRm$ebb5069ba3b4dda39a698bd1d9d7f5f848af3bd93b11e0cde2b28e9e34bfbbae
