+## Runtime Support
+
+### Node.js
+
+The current version of this library supports Node `18` and `20` (recommended). Node.js is the main supported platform which is also used internally for development and testing.
+
+TypeScript examples in the [examples](./examples/) folder can be run using [tsx](https://github.com/privatenumber/tsx) like the following:
+
+```shell
+tsx examples/simple.ts
+```
+
+### Bun
+
+This library has been tested to run with [Bun](https://bun.sh/) [v1.0](https://bun.sh/blog/bun-v1.0) or higher. Note that Bun is still in very active development and a production usage is not recommended (by the Bun team itself) in many cases.
+
+Example run using Bun:
+
+```shell
+bun run examples/simple.ts
+```
+
+### Browser
+
+This library targets to run in modern browsers which support the JavaScript [ES2020](https://www.w3schools.com/js/js_2020.asp) feature set. There is a dedicated ESM build provided and imports can be done using the normal ES6 [module import](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) syntax.
+
+For browser usage see the dedicated [example](./examples/browser.html) (with usage instructions).

-## Browser
-
-With the breaking release round in Summer 2023 we have added hybrid ESM/CJS builds for all our libraries (see section below) and have eliminated many of the caveats which had previously prevented a frictionless browser usage.
-
-It is now easily possible to run a browser build of one of the EthereumJS libraries within a modern browser using the provided ESM build. For a setup example see [./examples/browser.html](./examples/browser.html).
