  +
  +Click the 'Edit Settings' button, and choose an option for entering your IdP's information: a meta-data URL from your IdP, an XML file from your IdP, or by entering the data manually.

  +
  +## Set up manually
  +
  +There are two ways to set up your custom provider: using your Buildkite meta-data XML URL, or manually adding your Buildkite data into your identity provider. 
  +
  +### Set up your IdP
   
   Manual setup is different for each provider, however it usually requires the following fields:
   
  
positive.code:     </tr>
  </table>
  
  If your IdP requires an ACS URL, follow the instructions in Option A to generate one.
  
  If your custom provider needs further information, please email support@buildkite.com.
  
  ## Step 2. Configure a Buildkite SSO Provider
  
  ## Option A - Update your existing SSO Provider
  
  If you haven't done so already, create a Custom SAML Provider. In your Buildkite Organization Settings' Single Sign On menu item, choose the Custom SAML provider:
  
  <%= image "sso-settings.png", width: 1458/2, height: 926/2, alt: "Screenshot of the Buildkite SSO Settings Page" %>
  
  On the following screen you can choose to either set up using a Meta Data URL from your IdP, an XML file, or by entering the following 3 fields:
  
  <table>
      <tr>
  
negative.code: 
  <%= image "custom-saml-settings.png", width: 1746/2, height: 926/2, alt: "Screenshot of the Buildkite Custom SAML Settings Page" %>
  
  After completing your chosen option, [Perform a test login](#perform-a-test-login), then [Enable the new SSO provider](#enable-the-new-sso-provider).
  
  ## Perform a test login
  
  Follow the instructions to perform a test login. Performing a test login will verify that SSO is working correctly before you activate it for your organization members.
  
  ## Enable the new SSO provider
  
  Once you've performed a test login you can enable your provider. Activating SSO will not force a log out of existing users, but will cause all new or expired sessions to authorize through your provider before organization data can be accessed.
