+<Step>
+
+## TikTok OAuth App
+
+### Register the Application
+
+The first step is to create and register an OAuth App on the TikTok developer console to obtain access to the user's resources.
+
+1. Navigate to your TikTok Developer Portal and go to **Developer Portal > Manage apps**.
+2. Click **Connect an app**.
+3. Select **Individual** or **Organization** ownership and click **Confirm**.
+4. Fill in the "App name" and "App type".
+5. Fill the **Basic information** section with the required details.
+   - App icon: 1024 x 1024 px
+   - Category: Select the most relevant category for your app.
+   - Description: Description of your app's functionality and purpose.
+   - Terms of Service URL: Link to your app's terms of service.
+   - Privacy Policy URL: Link to your app's privacy policy.
+   - Platforms: Select the platforms your app will support (e.g., Web, Desktop, iOS, Android).
+6. Fill the **App review** section required to pass the TikTok review process.
+   - Short description: A concise summary of your app's functionality (max 1000 characters).
+7. Add scopes required for your app to function properly. For example, if you need to access user profile information, you would add the `user.info.basic` scope.
+8. Read teh complete [App Review Guidelines](https://developers.tiktok.com/doc/app-review-guidelines) to ensure your app meets all requirements before submission.
+9. Click **Submit for review**.
+10. Ensure you copy the **Client ID** and click **Generate a new client secret**.
+
+</Step>
+
+<Step>
+
+## Installation
+
+Install the package using a package manager like `npm`, `pnpm`, or `yarn`:
+
+```npm
+npm install @aura-stack/auth
+```
+
+</Step>
+
+<Step>
+
+## Environment setup
+
+Now, you must configure the environment variables required by Aura Auth, including the GitHub credentials and the encryption secrets.
+
+```bash title=".env" lineNumbers
+# Aura Secrets
+AURA_AUTH_SECRET="your-32-byte-secret"
+AURA_AUTH_SALT="your-32-byte-salt"
+
+# TikTok Credentials
+AURA_AUTH_TIKTOKE_CLIENT_ID="your_tiktok_client_id"
+AURA_AUTH_TIKTOKE_CLIENT_SECRET="your_tiktok_client_secret"
+```
+
+<Callout type="warn">
+  **CRITICAL SECURITY WARNING:** The `AURA_AUTH_SECRET` and `AURA_AUTH_SALT` variables are used to encrypt and sign user sessions.
+  These MUST be securely generated, highly randomized strings consisting of at least 32 bytes to ensure adequate entropy. Never
+  hardcode these values in your repository. Use a secure generator (like `openssl rand -base64 32`) to create them, and store them
+  exclusively in your secure environment variables manager.
+</Callout>
+
+</Step>
+
+<Step>
+
+## Configure the Auth Instance
+
+Configure the `createAuth` instance inside an `auth.ts` file located at the root of your project. Ensure you explicitly export the `handlers`, `api`, and `jose` objects.
+
+```ts title="auth.ts" lineNumbers
+import { createAuth } from "@aura-stack/auth"
+
+export const auth = createAuth({
+  oauth: ["tiktok"],
+})
+
+// Extract the required utilities
+export const { handlers, api, jose } = auth
+```
+
+<Callout type="info">
+  The `handlers` object contains mapping utilities for standard HTTP methods (`GET`, `POST`, `PATCH`) as well as a unified `ALL`
+  handler. This allows you to easily mount the authentication routes across any framework (Next.js, Elysia, Express, etc.).
+</Callout>
+
+</Step>
+
+<Step>
+
+## Customizing the OAuth Provider
+
+If you need to define custom scopes, change the response type, or map profile data differently, you can use the provider's factory function instead of a simple string identifier.
+
+```ts title="auth.ts" lineNumbers
+import { createAuth } from "@aura-stack/auth"
+import { tiktok } from "@aura-stack/auth/oauth/tiktok"
+
+export const auth = createAuth({
+  oauth: [
+    tiktok({
+      authorize: {
+        params: {
+          // Override default scopes
+          scope: "user.info.stats",
+        },
+      },
+    }),
+  ],
+})
+
+export const { handlers, api, jose } = auth
+```
+
+</Step>
+
+<Step>
+
+## Sign In to TikTok (Client & Server)
+
+There are multiple ways to trigger the sign-in flow depending on your ecosystem.
+
+### Sign-in Path (Direct Navigation)
+
+The common route to trigger the auth flow natively without needing a client library is simply navigating the browser to:
+`http://localhost:3000/auth/signIn/tiktok`
+
+---
+
+### Client-Side (React, Vue, etc.)
+
+You can utilize the `createAuthClient` utility to programmatically trigger sign-ins. You can also define a `redirectTo` destination.
+
+<Callout type="warn">
+  **Constraint Rule**: The `baseURL` passed into `createAuthClient` MUST exactly match the root domain and path where the HTTP
+  `handlers` expose their endpoints on the server.
+</Callout>
+
+```ts title="components/Login.tsx" lineNumbers
+import { createAuthClient } from "@aura-stack/auth/client"
+
+export const authClient = createAuthClient({
+  baseURL: "http://localhost:3000/auth",
+})
+
+const triggerSignIn = async () => {
+  await authClient.signIn("tiktok", {
+    redirectTo: "/dashboard",
+  })
+}
+```
+
+---
+
+### Server-Side (Next.js Actions, Remix Loaders, etc.)
+
+For environments supporting server-side actions, use the programmatic `api.signIn` method securely.
+
+```ts title="actions.ts" lineNumbers
+import { api } from "./auth"
+
+export const serverSignIn = async () => {
+  const response = await api.signIn("tiktok", {
+    redirectTo: "http://localhost:3000/dashboard",
+  })
+
+  // Example returning redirect location
+  return response.headers.get("Location")
+}
+```
+
+---
+
+### Session Retrieval
+
+After a user successfully signs in, you can retrieve their session data securely.
+
+**Client-Side:**
+
+```ts
+const session = await authClient.getSession()
+console.log(session?.user) // The authenticated TikTok user profile
+```
+
+**Server-Side:**
+
+```ts
+// Note: You must pass the native Web Request object or Headers!
+const session = await api.getSession(request)
+console.log(session?.user) // Safely retrieved backend session
+```
+
+</Step>
+
+</Steps>
