Optimizing Godot Size

Question

I searched for optimizing a build for size in godot docs
and I found some codes.......The problem is where can i write it?

scons p=windows target=release tools=no disable3d=yes
scons p=windows target=release tools=no disableadvanced_gui=yes

I notice that the instruction mentioned about build flag......

Sorry for this question, it might sound dumb but i am not familiar with command prompt....:D

First, you need to set up the build environment for the platform you are targeting.

Here's the docs for windows:
https://docs.godotengine.org/en/3.1/development/compiling/compiling_for_windows.html

And here the general docs for that topic:
https://docs.godotengine.org/en/3.1/development/compiling/index.html

If that is done, you usually can execute scons from the command line (inside the godot project/source directory).
