+# SDK mode
+
+EC can be build in sdk mode. This will result in a compiled js file that can be imported in very simple webapps.
+
+It allows to use matrixRTC in combination with livekit without relying on element call.
+
+This is done by instantiating the call view model and exposing some useful behaviors (observables) and methods.
+
+This folder contains an example index.html file that showcases the sdk in use (hosted on localhost:8123 with a webserver ellowing cors (for example `npx serve -l 81234 --cors`)) as a godot engine HTML export template.
+
+## Widgets
+
+The sdk mode is particularly interesting to be used in widgets where you do not need to pay attention to matrix login/cs api ...
+To create a widget see the example index.html file in this folder. And add it to EW via:
+`/addwidget <widgetUrl>` (see **url parameters** for more details on `<widgetUrl>`)
+
+### url parameters
+
+```
+widgetId = $matrix_widget_id
+perParticipantE2EE = true
+userId = $matrix_user_id
+deviceId = $org.matrix.msc3819.matrix_device_id
+baseUrl = $org.matrix.msc4039.matrix_base_url
+```
+
+`parentUrl = // will be inserted automatically`
+
+Full template use as `<widgetUrl>`:
+
+```
+http://localhost:3000?widgetId=$matrix_widget_id&perParticipantE2EE=true&userId=$matrix_user_id&deviceId=$org.matrix.msc3819.matrix_device_id&baseUrl=$org.matrix.msc4039.matrix_base_url&roomId=$matrix_room_id
+```
+
+the `$` prefixed variables will be replaced by EW on widget instantiation. (e.g. `$matrix_user_id` -> `@user:example.com` (url encoding will also be applied automatically by EW) -> `%40user%3Aexample.com`)
