+      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

+      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,

+      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:

+
+      (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.
+

+
+frp 是一个专注于内网穿透的高性能的反向代理应用，支持 TCP、UDP、HTTP、HTTPS 等多种协议，且支持 P2P 通信。可以将内网服务以安全、便捷的方式通过具有公网 IP 节点的中转暴露到公网。

+
+## 为什么使用 frp ？
+
+通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：
+
+* 客户端服务端通信支持 TCP、QUIC、KCP 以及 Websocket 等多种协议。
+* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间，降低请求延迟。
+* 代理组间的负载均衡。
+* 端口复用，多个服务通过同一个服务端端口暴露。
+* 支持 P2P 通信，流量不经过服务器中转，充分利用带宽资源。
+* 多个原生支持的客户端插件（静态文件查看，HTTPS/HTTP 协议转换，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
+* 高度扩展性的服务端插件系统，易于结合自身需求进行功能扩展。
+* 服务端和客户端 UI 页面。
+
+## 开发状态
+
+frp 目前已被很多公司广泛用于测试、生产环境。
+
+master 分支用于发布稳定版本，dev 分支用于开发，您可以尝试下载最新的 release 版本进行测试。
+
+我们正在进行 v2 大版本的开发，将会尝试在各个方面进行重构和升级，且不会与 v1 版本进行兼容，预计会持续较长的一段时间。
+
+现在的 v0 版本将会在合适的时间切换为 v1 版本并且保证兼容性，后续只做 bug 修复和优化，不再进行大的功能性更新。
+
+### 关于 v2 的一些说明
+
+v2 版本的复杂度和难度比我们预期的要高得多。我只能利用零散的时间进行开发，而且由于上下文经常被打断，效率极低。由于这种情况可能会持续一段时间，我们仍然会在当前版本上进行一些优化和迭代，直到我们有更多空闲时间来推进大版本的重构，或者也有可能放弃一次性的重构，而是采用渐进的方式在当前版本上逐步做一些可能会导致不兼容的修改。

+v2 的构想是基于我多年在云原生领域，特别是在 K8s 和 ServiceMesh 方面的工作经验和思考。它的核心是一个现代化的四层和七层代理，类似于 envoy。这个代理本身高度可扩展，不仅可以用于实现内网穿透的功能，还可以应用于更多领域。在这个高度可扩展的内核基础上，我们将实现 frp v1 中的所有功能，并且能够以一种更加优雅的方式实现原先架构中无法实现或不易实现的功能。同时，我们将保持高效的开发和迭代能力。
+
+除此之外，我希望 frp 本身也成为一个高度可扩展的系统和平台，就像我们可以基于 K8s 提供一系列扩展能力一样。在 K8s 上，我们可以根据企业需求进行定制化开发，例如使用 CRD、controller 模式、webhook、CSI 和 CNI 等。在 frp v1 中，我们引入了服务端插件的概念，实现了一些简单的扩展性。但是，它实际上依赖于简单的 HTTP 协议，并且需要用户自己启动独立的进程和管理。这种方式远远不够灵活和方便，而且现实世界的需求千差万别，我们不能期望一个由少数人维护的非营利性开源项目能够满足所有人的需求。
+
+最后，我们意识到像配置管理、权限验证、证书管理和管理 API 等模块的当前设计并不够现代化。尽管我们可能在 v1 版本中进行一些优化，但确保兼容性是一个令人头疼的问题，需要投入大量精力来解决。
+
+非常感谢您对 frp 的支持。
