+
+<!-- /automd -->
+
+Import utils:
+
+<!-- automd:jsimport cjs src="./src/index.ts"-->
+
+**ESM** (Node.js, Bun)
+
+```js
+import {
+  defaults,
+  parse,
+  parseFile,
+  read,
+  readUser,
+  serialize,
+  write,
+  writeUser,
+  update,
+  updateUser,
+} from "rc9";
+```
+
+**CommonJS** (Legacy Node.js)
+
+```js
+const {
+  defaults,
+  parse,
+  parseFile,
+  read,
+  readUser,
+  serialize,
+  write,
+  writeUser,
+  update,
+  updateUser,
+} = require("rc9");
+```
+
+<!-- /automd -->
+
+
+## Usage
+
+`.conf`:
+
+```ini
+db.username=username
+db.password=multi word password
+db.enabled=true
+```
+
+**Update config:**
+
+```ts
+update({ 'db.enabled': false }) // or update(..., { name: '.conf' })
+```
+
+Push to an array:
+
+```ts
+update({ 'modules[]': 'test' })
+```
+
+**Read/Write config:**
+
+```ts
+const config = read() // or read('.conf')
+
+// config = {
+//   db: {
+//     username: 'username',
+//     password: 'multi word password',
+//     enabled: true
+//   }
+// }
+
+config.enabled = false
+write(config) // or write(config, '.conf')
+```
+
+**User Config:**
+
+It is common to keep config in user home directory (MacOS: `/Users/{name}`, Linux: `/home/{name}`, Windows: `C:\users\{name}`)
+
+you can use `readUser`/`writeuser`/`updateUser` shortcuts to quickly do this:
+
+```js
+writeUser({ token: 123 }, '.zoorc') // Will be saved in {home}/.zoorc
+
+const conf = readUser('.zoorc') // { token: 123 }
+```
+
+## Unflatten
+
+RC uses [flat](https://www.npmjs.com/package/flat) to automatically flat/unflat when writing and reading rcfile.
+
+It means that you can use `.` for keys to define objects. Some examples:
+
+- `hello.world = true` <=> `{ hello: { world: true }`
+- `test.0 = A` <=> `tags: [ 'A' ]`
+
+**Note:** If you use keys that can override like `x=` and `x.y=`, you can disable this feature by passing `flat: true` option.
+
+**Tip:** You can use keys ending with `[]` to push to an array like `test[]=A`
+
+## Native Values
+
+RC uses [destr](https://www.npmjs.com/package/destr) to convert values into native javascript values.
+
+So reading `count=123` results `{ count: 123 }` (instead of `{ count: "123" }`) if you want to preserve strings as is, can use `count="123"`.
+
+## Exports
+
+```ts
+const defaults: RCOptions;
+function parse(contents: string, options?: RCOptions): RC
+function parseFile(path: string, options?: RCOptions): RC
+function read(options?: RCOptions | string): RC;
+function readUser(options?: RCOptions | string): RC;
+function serialize(config: RC): string;
+function write(config: RC, options?: RCOptions | string): void;
+function writeUser(config: RC, options?: RCOptions | string): void;
+function update(config: RC, options?: RCOptions | string): RC;
+function updateUser(config: RC, options?: RCOptions | string): RC;
+```
+
+**Types:**
+
+```ts
+type RC = Record<string, any>;
+interface RCOptions {
+    name?: string;
+    dir?: string;
+    flat?: boolean;
+}
+```
+
+**Defaults:**
+
+```ini
+{
