+### 特殊独立选项
+The options used for [doctoc](https://github.com/technote-space/doctoc#example) can be commented to specify values.  
+If you want to generate multiple TOCs with different settings, specify the values individually as follows.
+
+示例
+```markdown
+<!-- START doctoc -->
+<!-- param::isNotitle::true:: -->
+<!-- param::isCustomMode::true:: -->
+
+<!-- END doctoc -->
+
+...
+
+```
+
+## Action 事件详情
+### 目标事件
+| eventName: action | condition |
+|:---|:---|
+|push: *|[condition1](#condition1)|
+|pull_request: \[opened, synchronize, reopened, labeled, unlabeled]|[condition2](#condition2)|
+|pull_request: \[closed]||
+|schedule, repository_dispatch, workflow_dispatch||
+
+- 以下活动类型必须明确指定 （[详情](https://help.github.com/en/github/automating-your-workflow-with-github-actions/events-that-trigger-workflows#pull-request-event-pull_request)）
+  - `labeled`, `unlabeled`, `closed`
+### 条件
+#### condition1
+- 推送到分支 (不是tag)
+  - 分支名称 ([`TARGET_BRANCH_PREFIX`](#options))
+#### condition2
+- 包含指定标签？ ([`INCLUDE_LABELS`](#options))
+- 分支名称 ([`TARGET_BRANCH_PREFIX`](#options))
+
+## 附加说明
+### GITHUB_TOKEN
+ `GITHUB_TOKEN` 作为 `GitHub Actions` 的一部分，没有授权来创建任何后续事件。 
+因此它不会产生由推送触发的 action 。
+
+如果你配置了分支保护策略，这会是个问题。
+
+如果你想触发 action，使用个人访问令牌来代替。
+1. 生成一个 [个人访问令牌](https://help.github.com/en/articles/creating-a-personal-access-token-for-the-command-line) ，范围需选择 public_repo 或 repo 。  
+（私有仓库必须选择 repo）。  
+1. [保存为ACCESS_TOKEN](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets)
+1. 使用 `ACCESS_TOKEN` 代替 `GITHUB_TOKEN` 作为输入。
+   示例 `.github/workflows/toc.yml`
+   ```yaml
+   on: push
+   name: TOC Generator
+   jobs:
+     generateTOC:
+       name: TOC Generator
+       runs-on: ubuntu-latest
+       steps:
+         - uses: technote-space/toc-generator@v4
+           with:
+             GITHUB_TOKEN: ${{ secrets.ACCESS_TOKEN }}
+   ```
+
+### 创建 PullRequest
+如果 `CREATE_PR` 设置为 `true`，则会创建一个 PR 。  
+
+```yaml
+on: pull_request
+name: TOC Generator
+jobs:
+  generateTOC:
+    name: TOC Generator
+    runs-on: ubuntu-latest
+    steps:
+      - uses: technote-space/toc-generator@v4
+        with:
+          CREATE_PR: true
+```
+
+![创建 PR](https://raw.githubusercontent.com/technote-space/toc-generator/images/create_pr.png)
+
+如果活动类型设置为 `closed`，则该 action 会在 PR 不再需要时关闭它 。 
+
+```yaml
+on:
+  pull_request:
+    types: [opened, synchronize, reopened, closed]
+name: TOC Generator
+jobs:
+  generateTOC:
+    name: TOC Generator
+    runs-on: ubuntu-latest
+    steps:
+      - uses: technote-space/toc-generator@v4
+```
+
+### 上下文变量
+| 名称 | 描述 |
+|:---|:---|
+| PR_NUMBER | pull_request.number (如 `11`) |
+| PR_NUMBER_REF | `#${pull_request.number}` (如 `#11`) |
+| PR_ID | pull_request.id (如 `21031067`) |
+| PR_HEAD_REF | pull_request.head.ref (如 `change`) |
+| PR_BASE_REF | pull_request.base.ref (如 `main`) |
+| PR_MERGE_REF | pull_request.base.ref (如 `change -> main`) |
+| PR_TITLE | pull_request.title (如 `update the README with new information.`) |
+
+[Payload 示例](https://developer.github.com/v3/activity/events/types/#webhook-payload-example-28)
+
+### 上下文 PR 变量
+- [上下文变量](#context-variables)
+
+| 名称 | 描述 |
+|:---|:---|
+| PR_LINK | PR 链接 |
+| COMMANDS_OUTPUT | TOC 命令结果 |
+| FILES_SUMMARY | 如 `Changed 2 files` |
+| FILES | 变更文件列表 |
+
+## 配置示例 Examples
+### 示例 1
+在没有限制的分支上push时执行 action 并直接提交。
+
+```yaml
+on: push
+name: TOC Generator
+jobs:
+  generateTOC:
+    name: TOC Generator
+    runs-on: ubuntu-latest
+    steps:
+      - uses: technote-space/toc-generator@v4
+```
+
+### 示例 2
+通过仅对以 `release/` 开头的分支执行 PR 更新操作，从而创建或更新 PR。
+
+```yaml
+on:
+  pull_request:
+    types: [opened, synchronize, reopened, closed]
+name: TOC Generator
+jobs:
+  generateTOC:
+    name: TOC Generator
+    runs-on: ubuntu-latest
+    steps:
+      - uses: technote-space/toc-generator@v4
+        with:
+          CREATE_PR: true
+          TARGET_BRANCH_PREFIX: release/
+```
+
+### 示例 3
+仅在默认分支定时执行action并直接提交。
+（使用为其他 workflow 运行而创建的 Token）
+
+```yaml
+on:
+  schedule:
+    - cron: "0 23 * * *"
+name: TOC Generator
+jobs:
+  generateTOC:
+    name: TOC Generator
+    runs-on: ubuntu-latest
+    steps:
+      - uses: technote-space/toc-generator@v4
+        with:
+          GITHUB_TOKEN: ${{ secrets.ACCESS_TOKEN }}
+          CHECK_ONLY_DEFAULT_BRANCH: true
+```
