+## LinkedIn Setup
+
+LinkedIn currently uses a **personal access token** stored in `.env`. A full OAuth 2.0 flow is in the pipeline.
+
+### Step 1 — Create a LinkedIn App
+
+1. Go to [linkedin.com/developers/apps](https://www.linkedin.com/developers/apps) and click **Create App**
+2. Fill in the app name, LinkedIn Page (required — create a company page if you don't have one), and logo
+3. Under the **Products** tab, request access to:
+   - **Share on LinkedIn** — enables posting to your profile/page
+   - **Sign In with LinkedIn using OpenID Connect** — enables OAuth login (needed for the upcoming OAuth flow)
+4. Under **Auth**, note your **Client ID** and **Client Secret**
+5. Add your redirect URI under **OAuth 2.0 Settings**:
+
+   ```text
+   http://localhost:8081/api/auth/linkedin/callback
+   ```
+
+### Step 2 — Generate an Access Token
+
+Until the OAuth flow is built, generate a token manually:
+
+1. Use the [LinkedIn Token Generator](https://www.linkedin.com/developers/tools/oauth/token-generator) in the developer portal
+2. Select scopes: `w_member_social`, `r_liteprofile`, `r_emailaddress`
+3. Copy the generated access token
+
+### Step 3 — Add to `.env`
+
+```env
+LINKEDIN_ACCESS_TOKEN=your_token_here
+```
+
+> **Note:** Manual tokens expire after 60 days. A full OAuth 2.0 connection flow (similar to the Meta flow) is planned in the pipeline — once built, you will connect LinkedIn from the Settings UI with one click and tokens will be refreshed automatically.
+

 ## Adding a New Language
 
 1. Create `ui/src/locales/xx.ts` (copy `en.ts` and translate)
 2. In `ui/src/locales/index.ts`:
+
    ```ts
    import xx from './xx'
    // Add to messages: { en, tr, xx }
    // Add to SUPPORTED_LOCALES: { code: 'xx', label: '...', flag: '🇽🇽' }
    ```
+
 3. Done — the language appears in the NavBar dropdown automatically
