 ## Example
 This example will create a release when a tag is pushed:

 ## Notes
 - You must provide a tag either via the action input or the git ref (i.e push / create a tag). If you do not provide a tag the action will fail.
 - If the tag of the release you are creating does not yet exist, you should set both the `tag` and `commit` action inputs. `commit` can point to a commit hash or a branch name (ex - `main`).
 - In the example above only required permissions for the action specified (which is `contents: write`). If you add other actions to the same workflow you should expand `permissions` block accordingly.

+## Action 输出
+
+| 输出名称   | 描述                     |
+| ---------- | ------------------------ |
+| id         | 创建的版本的标识符。     |
+| html_url   | 版本的 HTML URL。        |
+| upload_url | 将资产上传到版本的 URL。 |
+
+## 示例
+
+此示例将在推送一个标签时创建一个 Release：
+
+```yml
+name: Releases
+
+on:
+  push:
+    tags:
+    - '*'
+
+jobs:
+
+  build:
+    runs-on: ubuntu-latest
+    permissions:
+      contents: write
+    steps:
+    - uses: actions/checkout@v4
+    - uses: ncipollo/release-action@v1
+      with:
+        artifacts: "release.tar.gz,foo/*.txt"
+        bodyFile: "body.md"
+```
+
+## 注意
+
+- 您必须通过 Action 输入或 git ref 提供一个标签（即推送/创建标签）。如果不提供标签，Action 将会失败。
+- 如果您正在创建的版本的标签不存在，您应该同时设置标签和提交 Action 输入。 commit 可以指向提交 Hash 或分支名称（例如 - main）。
+- 在上面的示例中，只需要指定操作的权限（即 contents: write）。 如果您将其他操作添加到同一工作流程，则应相应地扩展权限。
+- 有关于此 action 无法支持 discussion 的 Announcement 分类的原因的更多信息，请参见此处：https://github.com/goreleaser/goreleaser/issues/2304
