Step through TS editor code using source map

[jscsharp]

Currently, when you install the monaco-editor, the source map files are already been generated.
In source map we have ref file, like:
"file:///home/aeschli/workspaces/vscode/src/vs/base/common/diff/diffChange.ts",

What is the steps to add TS source files and able to debug and step through the TS code in browser?

Thanks

The instruction is here:
https://github.com/Microsoft/vscode/tree/master/build/monaco

I was not able to build it on Windows 10 machine , did not have time to look at the issues, but it took a few minutes to build it on Linux.
Just use a Monaco sample and use "Out-monaco-edior-core" folder from build and start debugging the ts files.
