+This guide references https://docs.snowflake.com/en/user-guide/ui-snowsight/notebooks-external-access
+
+We will need to configure the notebook to use external access integration with secrets.
+The `client_id` and `client_secret` can be generated by navigating to settings in the Chalk dashboard then selecting Access Tokens.
+```sql
+-- Step 1: Create secrets
+CREATE SECRET client_id
+  TYPE = GENERIC_STRING
+  SECRET_STRING = '<client_id>';
+CREATE SECRET client_secret
+  TYPE = GENERIC_STRING
+  SECRET_STRING = '<client_secret>';
+
+-- Step 2: Create a network rule
+CREATE OR REPLACE NETWORK RULE chalkpy_network_rule
+  MODE = EGRESS
+  TYPE = HOST_PORT
+  VALUE_LIST = ('api.chalk.ai');
+
+-- Step 3: Create an external access integration that uses the network rule and secret
+CREATE OR REPLACE EXTERNAL ACCESS INTEGRATION chalkpy_integration
+  ALLOWED_NETWORK_RULES = (chalkpy_network_rule)
+  ALLOWED_AUTHENTICATION_SECRETS = (client_id, client_secret)
+  ENABLED = true;
+
+-- Step 4: Associate with integration and secret with the notebook
+ALTER NOTEBOOK my_notebook
+  SET EXTERNAL_ACCESS_INTEGRATIONS = (chalkpy_integration),
+  SECRETS = ('client_id' = client_id, 'client_secret' = client_secret);
+
+-- Step 5: Grant the USAGE privilege on roles that will use the external access integration
+GRANT USAGE ON INTEGRATION chalkpy_integration TO ROLE my_notebook_role;
+```
+Accessing the secret inside a notebook
+```python
+import streamlit as st
+client_id = st.secrets['client_id']
+client_secret = st.secrets['client_secret']
+```
+
+Connecting using the Chalk Client
+```python
+from chalk.client import ChalkClient
+client = ChalkClient(
+  client_id=client_id,
+  client_secret=client_secret
+)
+```
