-# Svelte Cleanable Store
+# svelte-cleanable-store
+
+Custom Svelte store with built-in cleanup support on `subscribe`. Inspired by React's `useEffect` cleanup mechanism.
+
+**While the core functionality is simple and complete, this package is still pre-1.0 until I get feedback on the API shape.** (e.g. Is `cleanable` a confusing name? Do we need a `readable` equivalent as well?)
+
+## Usage
+
+```ts
+const state = cleanable(0);
+
+state.subscribe((value) => {
+    console.log(`state = ${value}`);
+    return () => console.log(`cleaning up ${value}...`);
+});
+```
+
+Console output:
+
+```ts
+state = 0
+
+// state++
+cleaning up 0...
+state = 1
+
+// state = 5
+cleaning up 1...
+state = 5
+```
+
+## Example
+
+### Closing a WebSocket connection
+
+```ts
+const path = cleanable("https://example.com/stream");
+path.subscribe((value) => {
+    const webSocket = new WebSocket(value);
+    webSocket.onmessage = (event) => console.log(event);
+
+    return () => webSocket.close();
+});
+```
+
+## But what about Svelte 5's `$effect`?
+
+It's absolutely great! In fact, it inspired me to create this package.
+
+However, Svelte 5 is still in beta now, and while there are many workarounds for Svelte 4, this package provides a clean, store-based solution that works with Svelte 4 (and 5), can be used anywhere (in plain `.js`/`.ts` files!), and is compatible with auto-subscriptions in `.svelte` files (with the `$` prefix), all without feeling like a hack.
