 Although the runtime would support database as a file, we don't recommend it. You'd need to also bundle the native dependencies which increases the deployment size and cold start time. Instead, we recommend you to use [LibSQL on Turso](/usage/database#sqlite-using-libsql-on-turso).

+In order to use **bknd**, you need to prepare access information to your database and potentially install additional dependencies. Connections to the database are managed using Kysely. Therefore, all [its dialects](https://kysely.dev/docs/dialects) are theoretically supported. 
 
+Currently supported and tested databases are:
+- SQLite (embedded): Node.js SQLite, Bun SQLite, LibSQL, SQLocal
+- SQLite (remote): Turso, Cloudflare D1
+- Postgres: Vanilla Postgres, Supabase, Neon, Xata
 
-## Database
+By default, bknd will try to use a SQLite database in-memory. Depending on your runtime, a different SQLite implementation will be used.
-### SQLite in-memory
+
-The easiest to get started is using SQLite in-memory. When serving the API in the "Integrations",
+## Defining the connection
-the function accepts an object with connection details. To use an in-memory database, you can either omit the object completely or explicitly use it as follows:
+There are mainly 3 ways to define the connection to your database, when
-```json
+1. creating an app using `App.create()` or `createApp()`
-{
+2. creating an app using a [Framework or Runtime adapter](/integration/introduction)
-   "url": ":memory:"
+3. starting a quick instance using the [CLI](/usage/cli#using-configuration-file-bknd-config)
-}
+
+When creating an app using `App.create()` or `createApp()`, you can pass a connection object in the configuration object.
+
+```typescript app.ts
+import { createApp } from "bknd";
+import { sqlite } from "bknd/adapter/sqlite";
+   
+// a connection is required when creating an app like this
+const app = createApp({
+   connection: sqlite({ url: ":memory:" }),
+});
 ```
 
-### SQLite as file
+When using an adapter, or using the CLI, bknd will automatically try to use a SQLite implementation depending on the runtime:
-Just like the in-memory option, using a file is just as easy:
 
-```json
-{
-   "url": "file:<path/to/your/database.db>"
-}
-```
-Please note that using SQLite as a file is only supported in server environments.
 
-### SQLite using LibSQL
+```javascript app.js
-Turso offers a SQLite-fork called LibSQL that runs a server around your SQLite database. To
+import { serve } from "bknd/adapter/node";
-point **bknd** to a local instance of LibSQL, [install Turso's CLI](https://docs.turso.tech/cli/introduction) and run the following command:
+
-```bash
+serve({
-turso dev
+   // connection is optional, but recommended
+   connection: { url: "file:data.db" },
+});
 ```
 
-The command will yield a URL. Use it in the connection object:
+You can also pass a connection instance to the `connection` property to explictly use a specific connection.
-```json
+
-{
+```javascript app.js
-   "url": "http://localhost:8080"
+import { serve } from "bknd/adapter/node";
-}
+import { sqlite } from "bknd/adapter/sqlite";

+

+```typescript bknd.config.ts

+import type { BkndConfig } from "bknd";
-   "url": "libsql://your-database-url.turso.io",
+
-   "authToken": "your-auth-token"
+export default {
-}
+   connection: { url: "file:data.db" },
+} as const satisfies BkndConfig;
 ```
 
+Throughout the documentation, it is assumed you use `bknd.config.ts` to define your connection.
+
+## SQLite
+### Using config object
+
+The `sqlite` adapter is automatically resolved based on the runtime. 
+
+| Runtime | Adapter | In-Memory | File | Remote |
+| ------- | ------- | --------- | ---- | ------ |
+| Node.js | `node:sqlite` | ✅ | ✅ | ❌ |
+| Bun | `bun:sqlite` | ✅ | ✅ | ❌ |
+| Cloudflare Worker/Browser/Edge | `libsql` | 🟠 | 🟠 | ✅ |
+
+The bundled version of the `libsql` connection only works with remote databases. However, you can pass in a `Client` from `@libsql/client`, see [LibSQL](#libsql) for more details.
+
+```typescript bknd.config.ts
+import type { BkndConfig } from "bknd";
+
+// no connection is required, bknd will use a SQLite database in-memory
+// this does not work on edge environments!
+export default {} as const satisfies BkndConfig;
+
+// or explicitly in-memory
+export default {
+   connection: { url: ":memory:" },
+} as const satisfies BkndConfig;
+
+// or explicitly as a file
+export default {
+   connection: { url: "file:<path/to/your/database.db>" },
+} as const satisfies BkndConfig;
+```
+
+
+### LibSQL
+Turso offers a SQLite-fork called LibSQL that runs a server around your SQLite database. The edge-version of the adapter is included in the bundle (remote only):
+
+```typescript bknd.config.ts
+import type { BkndConfig } from "bknd";
+import { libsql } from "bknd/data";
+
+export default {
+   connection: libsql({ 
+      url: "libsql://your-database-url.turso.io",
+      authToken: "your-auth-token",
+   }),
+} as const satisfies BkndConfig;
+```
+
+If you wish to use LibSQL as file, in-memory or make use of [Embedded Replicas](https://docs.turso.tech/features/embedded-replicas/introduction), you have to pass in the `Client` from `@libsql/client`: 
+
+```typescript bknd.config.ts
+import type { BkndConfig } from "bknd";
+import { libsql } from "bknd/data";
+import { createClient } from "@libsql/client";
+
+export default {
+   connection: libsql(createClient({ 
+      url: "libsql://your-database-url.turso.io",
+      authToken: "your-auth-token",
+   })),
+} as const satisfies BkndConfig;
+```
