Hello, I am a code review bot on flows.network. Here are my reviews of code commits in this PR.

---

Overall, the Pull Request seems well-prepared and the changes seem well-explained. The potential problems that were identified have been addressed. The addition of a new .md file to the docs/develop/c folder provides clear instructions for using the wasm_bpf plugin of the WasmEdge runtime, along with a standalone example and output. Additionally, spell errors in the previous version of bpf.md were fixed. Finally, new documentation for bootstrap was added with code snippets to demonstrate the use of BPF features. Thus, the changes in this Pull Request are useful and valuable additions to the project.

This looks great! Can you also add a section on how to install the eBPF plugin here?

https://wasmedge.org/docs/develop/build-and-run/install/#install-wasmedge-with-plugins-1

Thanks.

The install script doesn't seem to support installing wasm_bpf plugin yet, it only supports plugins with their names hardcoded in the script

Maybe we can open a pr and add the wasm_bpf plugin in it?

I will merge this first. When we have the installer for e-bpf plugin, the doc needs to be updated.
