+# Getting API Keys for OAuth Authentication
+
+Follow these steps to create and configure your OAuth credentials for using Google APIs.
+
+## 1. Create API Credentials
+
+1. Go to the [Google API Console](https://console.developers.google.com/).
+2. From the projects list, select an existing project or create a new one.
+3. In the left side menu, select **APIs & Services**.
+4. On the left menu, click **Credentials**.
+5. Click **Create Credentials** and select **OAuth client ID**.
+6. In the **Application type** section, select **Desktop app**.
+7. Provide an appropriate name for your client ID (e.g., "Gspread OAuth Client").
+8. Click **Create**.
+
+Once the credential is created, you will receive a **Client ID** and **Client Secret**. These are required for accessing the API.
+
+## 2. Store Your Credentials
+
+Save the **Client ID** and **Client Secret** in a `.env` within a `.secret` directory. The file should look like this:
+
+```bash
+CLIENT_ID=YOUR_CLIENT_ID
+CLIENT_SECRET=YOUR_SECRET_KEY
+```
+
+In most cases, only these two secrets are required.
+
+
+# Troubleshooting
+
+If you encounter problems with authentication or tokens, you will most likely need to add **AUTH_URI** or **TOKEN_URI** to the .env file. In such case all 4 secrets are requeired. To retrieve them, download the API key you created in JSON format. Open the file and copy the keys into the .env file. After making these changes, your .env file should look like this:
+
+```bash
+CLIENT_ID=YOUR_CLIENT_ID
+CLIENT_SECRET=YOUR_SECRET_KEY
+AUTH_URI=YOUR_AUTH_URI
+TOKEN_URI=YOUR_TOKEN_URI
+``` 
+
+If you still get some issues, follow [Google OAuth Documentation](https://developers.google.com/identity/protocols/oauth2/).
