+## Casdoor as a SAML IdP in Google Workspace
+
+This guide will show you how to configure Casdoor and Google Workspace to add Casdoor as a SAML IdP in Google Workspace
+
+### Add Certificate 
+
+In Casdoor, add a certificate of type X.509 with RSA crypto algorithm and download it.

+
+### Configure SAML Application
+
+In the application edit page, select the certificate you just created. Add the domain name of the Google application you will use in the **Redirect URLs**, such as google.com.
+

+
+In the **SAML reply URL** field, enter`https://www.google.com/a/<your domain>/acs`, which is the ACS URL. You can find relevant information about ACS URL here: [SSO assertion requirements](https://support.google.com/a/answer/6330801)

+
+Copy the **sigin page URL**. This will be used in the next step.

+
+### Add Third-Party SAML IdP for Google Workspace
+
+In the Google Workspace Admin console, navigate to **Security** and then **Overview**. Look for the **SSO with third-party Idp** section. 
+Click on Add SSO profile to access the editing page. Check the Set up SSO with third-party identity provider checkbox. Paste the copied sigin page URL into the **Sign-in page URL** and **Sign-out page URL** fields. Upload the certificate downloaded in the previous step. Click Save to save the changes.

+
+### Add Users for Testing
+
+In Google Workspace, create a user with the username "test" (you can customize the username, this is just an example).
+

+
+In Casdoor, add a user with the same username as set in Google Workspace. Make sure to select the appropriate organization and enter the user's email address.
+

+
+As an example using "google.com," follow these steps:
+1. Click on the login button on the Google.com page.
+Enter the user's email address to initiate the login process.
+2. You will be redirected to the Casdoor page.
+On the Casdoor page, enter the corresponding email address and password.
+3. If the login is successful, you will be redirected back to google.com
