+# Metabase Node.js Interactive Embedding Sample
+
+This is the sample code for the Metabase Node.js Interactive Embedding Quickstart.
+
+Please check out the code for an example of how to integrate interactive embedding into your Node.js applications.
+
+## What is Metabase?
+
+## Running the sample code
+1. Make sure you have updated enabled JWT for SSO under admin settings, and you have entered your app's SSO endpoint as the JWT Identity Provider URI. The path is `/sso/metabase`, e.g. `http://localhost:8080/sso/`metabase
+2. Make sure you define the following env vars defined:
+** `export METABASE_SITE_URL="https://myapp.metabaseapp.com"` - the root path of your Metabase instance,
+** `export METABASE_JWT_SHARED_SECRET="COPY_SECRET_FROM_JWT_CONFIG"` - you grab this from the SSO JWT config in admin settings
+3. Create a dashboard using X-ray on the invoices table in the sample dataset. If the ID is not 1, then update `METABASE_DASHBOARD_PATH` in `index.js`.  
+3. Start the sample with `node index.js`. It runs by default on port 8080.
+4. Hit http://localhost:8080, sign in and hit `/analytics` with both users to populate them to Metabase.
+5. Create groups `Customer Acme` and `Customer Fake` and configure permissions so they can access the collection in which the dashboard is located. Also, setup data sandboxing on the Invoices table filtering on `accountId`.
+6. Under SSO then activate group membership syncing and map `Customer-Acme` and `Customer-Fake` to the groups you've created.
+7. You should be able to sign in with the two users and see the dashboard. If not, check the collection permissions for their respective groups.
+8. Both users should be able to see the same dashboard but with different data, beacuse of sandboxing.
+
+## Create a free Metabase trial
+
+* For interactive embedding, you will need a Pro or Enterprise plan.
