-# Issue Helper
+# 🤖 Issue Helper
+
+一个完全帮你处理 issue 的 GitHub Action。
+
+## 列表
+
+
 
-一个可以帮助你处理 issue 的 GitHub Action。
 
 ## 使用
 
+### 基础
 
+#### `add-assignees`
+
+将一个 issue 增加指定人
+
+```yml
+- name: Add assigness
+  uses: actions-cool/issue-helper@v1
+  with:
+    token: ${{ secrets.GITHUB_TOKEN }}
+    issue-number: 1
+    assignees: 'xrkffgg'
+```
+
+| 参数 | 描述 | 类型 | 必填 | 版本 |
+| -- | -- | -- | -- | -- |
+| token | [token](#token) | string | ✖ | v1 |
+| issue-number | 指定的 issue，可通过 url 查看 | number | ✔ | v1 |
+
+## 参考
+
+### token
+
+需拥有 push 权限的人员 token。
+
+- [个人 token 申请](https://github.com/settings/tokens)
+  - 需勾选 `Full control of private repositories`
+- 项目添加 secrets
+  - 选择 settings，选择 secrets，选择 `New repository secret`
+  - `Name` 与 actions 中保持一致
+  - `Value` 填写刚才个人申请的 token
+
+当 actions 不填写 token 时，会默认为 github-actions <kbd>bot</kbd>。
+
