+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,

+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+

+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+## 官方文档 & Demo演示
+
+> **中文**：[https://100px.net](https://100px.net)
+
+> **English**：**If anyone can help translate the document, please contact me** `ldq404@qq.com`
+  
+<br />
+
+## 在 uni-app 中使用
+
+### 1. 安装插件
+
+- 你可以选择通过 `HBuilderX` 导入插件： [https://ext.dcloud.net.cn/plugin?id=3499](https://ext.dcloud.net.cn/plugin?id=3499)
+
+- 也可以选择通过 `npm` / `yarn` 安装
+
+```shell
+# npm 安装：
+npm install @lucky-canvas/uni
+
+# yarn 安装：
+yarn add @lucky-canvas/uni
+```
+
+<br />
+
+### 2. 引入并使用
+
+```html
+<view>
+  <!-- 大转盘抽奖 -->
+  <LuckyWheel
+    width="600rpx"
+    height="600rpx"
+    ...你的配置
+  />
+  <!-- 九宫格抽奖 -->
+  <LuckyGrid
+    width="600rpx"
+    height="600rpx"
+    ...你的配置
+  />
+</view>
+```
+
+```js
+// npm 下载会默认到 node_modules 里面，直接引入包名即可
+import LuckyWheel from '@lucky-canvas/uni/lucky-wheel' // 大转盘
+import LuckyGrid from '@lucky-canvas/uni/lucky-grid' // 九宫格
+
+// 如果你是通过 HBuilderX 导入插件，那你需要指定一下路径
+// import LuckyWheel from '@/components/@lucky-canvas/uni/lucky-wheel' // 大转盘
+// import LuckyGrid from '@/components/@lucky-canvas/uni/lucky-grid' // 九宫格
+
+export default {
+  // 注册组件
+  components: { LuckyWheel, LuckyGrid },
+}
+```
+
+<br />
+
+### 3. 我提供了一个最基本的 demo 供你用于尝试
+
+由于 uni-app 渲染 md 的时候会出问题，所以我把 demo 代码放到了文档里
+
+- [https://100px.net/usage/uni-app.html](https://100px.net/usage/uni-app.html)
+
+<br />
+
+### **4. 补充说明**
+
+- [**如果用着顺手, 可以在 Github 上面点个 <img height="22" align="top" src="https://img.shields.io/github/stars/buuing/lucky-canvas" /> 支持一下(●'◡'●)**](https://github.com/buuing/lucky-canvas)
+
+- 另外: 如果你修复了某些bug或兼容, 欢迎提给我, 我会把你展示到官网的贡献者列表当中
+
+
+<br />
+
+### 5. 常见问题
+
+1. 转盘层级太高了, 我的弹窗盖不住怎么办?
+
+> 答: 因为小程序里canvas是原生组件顶层渲染, 我无法控制canvas的层级, 如果你想盖住它也肯简单, 你可以百度搜索`<cover>`组件
+
+2. 你这些素材, 图片组件从哪下载?
+
+> 答: 官网里的任何图片素材, 所使用到的图片资源均为学习交流使用, 请勿将其用于商业用途, 由此产生的任何商业纠纷我这边概不负责
+
+3. xxx属性怎么使用? xxx方法怎么调用?
+
+> 答: 自己去看文档, 不然难道要我把代码给你写好吗?
+
+4. 这个属性的效果与官网的描述不一致?
+
+> 答: 可能有bug, 你可以去github上的issues去提问 (请认真填写模板)
+
+5. 为什么这个插件不支持app和其他小程序
+
+> 答: 没时间, 但是希望志同道合的同学来一起参与uniapp的兼容开发
