I have read the development guide and still confused about the development workflow. For example, my development environment is a Neovim + Clangd LSP server and I want to know how the update engine works, I git clone the code, but it can't build update engine standalone . So it's hard to read the source code. Maybe I'm going about it the wrong way. So can you tell me the correct way to write chromium OS code like normal software. And the appropriate development environment and tools.
