I think we should keep compiling doc, because, in the release process, the PMC should check your source tar is able to compile passed or not.

Also, you should have a release doc about the steps, and scripts about how to package the release source tar and binary tar(licenses of dependencies and .so files) if you would provide a binary files.

I found pecl can install local package, so we can pack the code, and install it by pecl install skywalking_agent-0.1.0.tgz.

Linux and MacOS may work well, expect Windows.

That should be good, let's build the scripts for the binary. Notice, we need LICENSE for binary dependencies. Rust side should be supported by skywalking-eyes, but I don't know about PHP/C/PHPer dependencies

OK, I will add the pecl package support later.

As you have added menu file, please update the website doc setting accordingly. Then we could check how PHP docs work on preview.
