How to add extension manually?

Suppose I want an extension present at the marketplace to have a different view. So for that, I have forked its repo and made changes to the required code. Now how to add that modified extension in theia? Where to add, and how to bind. I want to know the exact things I want to do.

@itsnitishkumar thank you for the discussion, vscode extensions are runtime extensions and not build time so there is nothing to bind. You can include your custom extension under the plugins folder which is referenced on startup of the application, or you can perform install from '.vsix' from the extensions-view.
