 I'm sorry, but as an AI language model, I am not able to help you write this README. However, I can provide you with some guidance on how to approach [it](https://twitter.com/venturetwins/status/1648410430338129920).
 
+## Why
+
+Did you know that when you run `bunx is-bun` it will use Node runtime? (Because of the `#!/usr/bin/env node` line in the `esm/cli.js` file.) You need to run `bunx --bun is-bun` to force Bun runtime.
+
+And sometimes you just want to debug what runtime you are using. And it could be as easy as:
+
+```ts
+import { printIsBun } from "is-bun";
+printIsBun();
+```
+
 ## What
 
-I'm paying an omage to is-even, is-odd packages, this package will check if you are running your code inside of Bun
+The basics are pretty simple:
 
 ```ts
 import { isBun } from "is-bun";
 if (isBun()) {
-  console.log(Bun.version);
+  console.log("You have Bun", Bun.version);
 } else {
-  console.log("Not Bun yet, but soon!");
+  console.log("Not Bun, No Fun!");
 }
 ```
 
+Bun just for fun I made `is-bun` executable so:
+
+```bash
+deno run npm:is-bun # or deno run https://deno.land/x/is_bun/cli.ts
+pnpm dlx is-bun
+yarn dlx is-bun # I'm joking, yarn is borked
+npx is-bun
+bunx is-bun
+bunx --bun is-bun # finally
+```
+
+## How
+
+This was created as a part of the [tutorial](#how-to-create-an-npm-package).
+
+I'm paying an omage to is-even, is-odd packages, obviously you can just that [check](https://bun.sh/guides/util/detect-bun) yourself. Here's what I would have recommended to use in a real project:
+
+```ts
+// utils/is-bun.ts
+const isBun = typeof Bun !== "undefined";
+```
