-## Incremental writing with `FileSink`
-
-Bun provides a native incremental file writing API called `FileSink`. To retrieve a `FileSink` instance from a `BunFile`:
-
-```ts
-const file = Bun.file("output.txt");
-const writer = file.writer();
-```
-
-To incrementally write to the file, call `.write()`.
-
-```ts
-const file = Bun.file("output.txt");
-const writer = file.writer();
-
-writer.write("it was the best of times\n");
-writer.write("it was the worst of times\n");
-```
-
-These chunks will be buffered internally. To flush the buffer to disk, use `.flush()`. This returns the number of flushed bytes.
-
-```ts
-writer.flush(); // write buffer to disk
-```
-
-The buffer will also auto-flush when the `FileSink`'s _high water mark_ is reached; that is, when its internal buffer is full. This value can be configured.
-
-```ts
-const file = Bun.file("output.txt");
-const writer = file.writer({ highWaterMark: 1024 * 1024 }); // 1MB
-```
-
-To flush the buffer and close the file:
-
-```ts
-writer.end();
-```
-
-Note that, by default, the `bun` process will stay alive until this `FileSink` is explicitly closed with `.end()`. To opt out of this behavior, you can "unref" the instance.
-
-```ts
-writer.unref();
-
-// to "re-ref" it later
-writer.ref();
-```

-
-```ts

-
-const isMatch = await Bun.password.verify(password, hash);
-// => true
-```
-
-The second argument to `Bun.password.hash` accepts a params object that lets you pick and configure the hashing algorithm.
-
-```ts
-const password = "super-secure-pa$$word";
-
-// use argon2 (default)
-const argonHash = await Bun.password.hash(password, {
-  algorithm: "argon2id", // "argon2id" | "argon2i" | "argon2d"
-  memoryCost: 4, // memory usage in kibibytes
-  timeCost: 3, // the number of iterations
-});
-
-// use bcrypt
-const bcryptHash = await Bun.password.hash(password, {
-  algorithm: "bcrypt",
-  cost: 4, // number between 4-31
-});
-```
-
-The algorithm used to create the hash is stored in the hash itself. When using `bcrypt`, the returned hash is encoded in [Modular Crypt Format](https://passlib.readthedocs.io/en/stable/modular_crypt_format.html) for compatibility with most existing `bcrypt` implementations; with `argon2` the result is encoded in the newer [PHC format](https://github.com/P-H-C/phc-string-format/blob/master/phc-sf-spec.md).
-
-The `verify` function automatically detects the algorithm based on the input hash and use the correct verification method. It can correctly infer the algorithm from both PHC- or MCF-encoded hashes.
-
-```ts
-const password = "super-secure-pa$$word";
-
-const hash = await Bun.password.hash(password, {
-  /* config */
-});
-
-const isMatch = await Bun.password.verify(password, hash);
-// => true
-```
-
-Synchronous versions of all functions are also available. Keep in mind that these functions are computationally expensive, so using a blocking API may degrade application performance.
-
-```ts
-const password = "super-secure-pa$$word";
-
-const hash = Bun.password.hashSync(password, {
-  /* config */
-});
-
-const isMatch = Bun.password.verifySync(password, hash);

-
-To preload this file before `bun test`, open or create a `bunfig.toml` file and add the following lines.
-
-```toml
-[test]
-preload = "./happydom.ts"
-```
-
-This will execute `happydom.ts` when you run `bun test`. Now you can write tests that use browser APIs like `document` and `window`.
-
-```ts#dom.test.ts
-import {test, expect} from 'bun:test';
-
-test('dom test', () => {
-  document.body.innerHTML = `<button>My button</button>`;
-  const button = document.querySelector('button');
-  expect(button?.innerText).toEqual('My button');
-});
-```
-
-Depending on your `tsconfig.json` setup, you may see a `"Cannot find name 'document'"` type error in the code above. To "inject" the types for `document` and other browser APIs, add the following [triple-slash directive](https://www.typescriptlang.org/docs/handbook/triple-slash-directives.html) to the top of any test file.
-
-```ts-diff#dom.test.ts
-+ /// <reference lib="dom" />
-
-  import {test, expect} from 'bun:test';
-
-  test('dom test', () => {
-    document.body.innerHTML = `<button>My button</button>`;
-    const button = document.querySelector('button');
-    expect(button?.innerText).toEqual('My button');
-  });
-```
-
-Let's run this test with `bun test`:
-
-```bash
-$ bun test
-bun test v0.x.y
-
-dom.test.ts:
-✓ dom test [0.82ms]
-
- 1 pass
- 0 fail
- 1 expect() calls
-Ran 1 tests across 1 files. 1 total [125.00ms]
-```
-
-<!-- ## React Testing Library
-
-Once you've set up `happy-dom` as described above, you can use it with React Testing Library. To get started, install the `@testing-library/react` package as a dev dependency.
-
-```bash
-$ bun add -d @testing-library/react
-``` -->

+This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `pages/index.js`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.js`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
