+=================================
+Enable Certificate Sharing to LinkedIn
+=================================
+This guide explains how to configure the platform to allow learners to share their certificates directly to their LinkedIn profiles.
+
+To activate the **"Add Certificate to LinkedIn"** button for learners, set the following configuration value to `True`:
+
+   .. code-block:: none
+
+        'CERTIFICATE_LINKEDIN': True
+
+The organization name displayed on the shared certificate is determined by the following settings, in order of priority:
+
+#. Course-Specific Organization: To use the organization name defined for each individual course, enable this setting:
+
+   .. code-block:: none
+
+        'CERTIFICATE_LINKEDIN_DEFAULTS_TO_COURSE_ORGANIZATION_NAME': True
+
+#. Platform-Wide Company ID: To use a single, platform-wide company ID (found in your LinkedIn Company Page settings), configure this value:
+
+   .. code-block:: none
+
+        'LINKEDIN_COMPANY_ID': '133-TEST-ID'
+
+#. Platform Name Fallback: If neither of the above is configured, the platform's general name will be used as the organization name.
