+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, 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 1.1.1 (3.0 is unnecessary)
