+```
+
+2. Create the Spicepod.
+```shell 
+cat <<EOF > spicepod.yaml
+version: v1beta1
+kind: Spicepod
+name: file_quickstart
+datasets:
+  - name: yellow_taxis
+    from: file:yellow_tripdata_2024-01.parquet
+EOF
+```
+
+3. Run Spice runtime
+```shell
+spice run
+```
+
+4. Run SQL query
+```sql
+select avg(passenger_count) from taxi_trips
+```
+
+5. (Optional) Cleanup
+```shell

+  "delta-lake.md"
+)
+
+for file in "${files[@]}"; do

+done
+```
+
+2. Create the Spicepod.
+```shell
+cat <<EOF > spicepod.yaml
+version: v1beta1

+name: file_quickstart
+datasets:
+  - name: docs
+    from: file:./
