Missing instructions for building with local Servo repo

[userzimmermann]

Hi :) I'm new to Rust, but so far I managed to build Servo (on Windows), and after some failed attempts I figured out how to build ServoShell using my Servo clone as local requirement, by changing:

+++ b/Cargo.toml
...
-libservo = { git = "https://github.com/servo/servo", rev = "989d2fd532" }
+libservo = { path = "../engine/components/servo" }

• https://github.com/servo/servo in ...\Projects\servo\engine
• ServoShell in ...\Projects\servo\shell

(Directly building w/cargo build instead of using mach)

Is there some less intrusive way for defining the local Servo dependency (w/o the need to make changes to tracked files like Cargo.toml)? And could you please briefly explain the preferred way in your README?

You can add this to Cargo.toml:

[patch."https://github.com/servo/servo"]
libservo = { path = "/path/to/local/checkout" }

Haven't tried, but that should do it.
