-There is currently no list of officially supported browsers. OpenTelemetry is developed using standard web
-technologies and aims to work in currently supported versions of major browsers.
+Rather than define versions of specific browsers / runtimes, OpenTelemetry sets the minimum supported version based on the
+underlying language features used.
+
+The current minumum language feature support is set as [ECMAScript 2020](https://262.ecma-international.org/11.0/) that are available
+in all modern browsers / runtimes.
+
+This means that if you are targeting or your end-users are using a browser / runtime that does not support ES2020, you will need
+to transpile the code and provide any necessary polyfills for the missing features to ensure compatibility with your target
+environments. Any support issues that arise from using a browser or runtime that does not support ES2020 will be closed as "won't fix".
+
+This minimum support level is subject to change as the project evolves and as the underlying language features evolve.
