Disclaimer: This is NOT a product of Huawei Technologies Co., Ltd. This package is created in order to help some people working with Huawei or inside Huawei to render some documents in LaTeX format. You are welcome to use it at your own risk.

First, install it from CTAN and then use in the preamble:

\documentclass[landscape]{huawei}
\renewcommand*\theauthor{Yegor Bugayenko}
\renewcommand*\thetitle{An Interesting Document About Something}
\begin{document}
\maketitle
Hello, world!
\end{document}

Otherwise, you can download huawei.cls and add to your project.

Read the detailed documentation in PDF.

If you need more formatting options, submit an issue, I'll implement them.

If you want to contribute yourself, make a fork, then create a branch, then run make in the root directory. It should compile everything without errors. If not, submit an issue and wait. Otherwise, make your changes and then run make again. If the build is still clean, submit a pull request.
