-## Google Calendar API Authentication with OAuth2
-
-This guide will help you set up OAuth2 authentication for your Google Calendar API. Follow these steps to create a project, enable the API, and obtain the necessary credentials.
-
-### Step 1: Create a New Project
-1. Go to the [Google Developer Console](https://console.developers.google.com/).
-2. Click on the **Create Project** button.
-3. Enter a name for your project and click **Create**.
-
-### Step 2: Enable the Google Calendar API
-1. In the [Google Developer Console](https://console.developers.google.com/), navigate to the **Library** section.
-2. Search for "Google Calendar API".
-3. Click on the **Google Calendar API** and then click **Enable**.
-
-### Step 3: Create OAuth2 Consent Screen
-1. In the [Google Developer Console](https://console.developers.google.com/), navigate to the **OAuth consent screen** section.
-2. Choose **External** as the user type and click **Create**.
-3. Fill out the required app information:
-   - **App name**: `gcalcli`
-   - **User support email**: `[email protected]`
-4. Fill out the required developer contact information:
-   - **Email addresses**: `[email protected]`
-5. Click **Save and continue**.
-6. Under **Scopes**, click **Save and continue**.
-7. Under **Test users**, add your email (`[email protected]`).
-8. Click **Save and continue**.
-
-### Step 4: Create OAuth Client ID
-1. In the [Google Developer Console](https://console.developers.google.com/), navigate to the **Credentials** section.
-2. Click **Create credentials** and select **OAuth client ID**.
-3. Select **Application type: Desktop app**.
-4. Click **Create**.
-5. Download the JSON file containing your client ID and secret.
-
-### Step 5: Configure gcalcli
-1. Create a directory for gcalcli configuration:
-    ```sh
-    mkdir -p ~/.gcal
-    ```
-2. Place the downloaded JSON file into the `~/.gcal` directory:
-    ```sh
-    mv /path/to/your/downloaded/secret.json ~/.gcal/secret.json
-    ```
-
-### Step 6: Authenticate with Google
+
+## Authentication
+
+By default, a hardcoded and unverified Google secret is included in the project. This secret has a user cap limit and can be used temporarily. If you want to use your custom authentication (via Google Console), you can find step-by-step instructions [here](docs/custom_auth.md).
+
+How it works in the background ?
+
 1. Start gcalcli. The authentication process will begin automatically.
 2. Follow the instructions to complete the authentication process.
 
 The resulting token will be stored in the `~/.gcal/store.json` file.
-
-By following these steps, you will have successfully set up OAuth2 authentication for your Google Calendar API using gcalcli.
