+# kLoop
+
+kLoop is an implementation of the Python
+[asyncio](https://docs.python.org/3/library/asyncio.html) event loop written
+in [Cython](https://cython.org/), using
+[io_uring](https://unixism.net/loti/what_is_io_uring.html) and
+[kTLS](https://www.kernel.org/doc/html/latest/networking/tls-offload.html)
+features of the Linux kernel, therefore called k(ernel)Loop.
+
+kLoop is open-sourced and released under the
+[MulanPSL - 2.0 license](http://license.coscl.org.cn/MulanPSL2).
+
+**⚠️WARNING: THIS PROJECT IS IN PROOF-OF-CONCEPT STAGE!⚠️**
+
+
+## Requirements
+
+* Python >= 3.8
+* Linux >= 5.11 (enable kTLS with `modprobe ktls`)
+* OpenSSL >= 3.0

 # kLoop
 
-kLoop is an implementation of the Python
-[asyncio](https://docs.python.org/3/library/asyncio.html) event loop written

+
+kLoop 是一个 Python
+[asyncio](https://docs.python.org/3/library/asyncio.html) event loop 的实现，
+主要用 [Cython](https://cython.org/) 编写，重点使用了 Linux 内核的
+[io_uring](https://unixism.net/loti/what_is_io_uring.html) 和
 [kTLS](https://www.kernel.org/doc/html/latest/networking/tls-offload.html)
-features of the Linux kernel, open-sourced and released

+功能，故称作 k(ernel)Loop。

+您可在[木兰宽松许可证, 第2版](http://license.coscl.org.cn/MulanPSL2)的范围内使用
+kLoop 的源代码。

 * Python >= 3.8
-* Linux >= 5.11 (enable ktls with `modprobe ktls`)
-* OpenSSL 1.1.1 (3.0 is unnecessary)
-
+* Linux >= 5.11 (用 `modprobe ktls` 命令来启用 kTLS 模块)
+* OpenSSL >= 3.0
