 ##### NPM
 In node_modules/webrtc-adapter/out/ folder you will find 4 files:
 * `adapter.js` - includes all the shims and is visible in the browser under the global `adapter` object (window.adapter).
-* `adapter_no_edge.js` - same as above but does not include the Microsoft Edge (ORTC) shim.
-* `adapter_no_edge_no_global.js` - same as above but is not exposed/visible in the browser (you cannot call/interact with the shims in the browser).
 * `adapter_no_global.js` - same as `adapter.js` but is not exposed/visible in the browser (you cannot call/interact with the shims in the browser).
