+# Using Temporal (temporal.io) on Astra
+
+* Create an Astra DB at [https://astra.datastax.com/](https://astra.datastax.com/)
+* Add two keyspaces in the Astra DB UI via "Add Keyspace": `temporal` and `temporal_visibility`
+* Create a new Astra token and get your DB's identifier
+  * Update `.env` with your Astra token and DB identifier
+* Update the Temporal schema by running `./schema.sh` or:
+```sh
+docker-compose -f docker-compose-cqlproxy-schema.yml run temporal-admin-tools -ep cql-proxy -k temporal setup-schema -v 0.0
+docker-compose -f docker-compose-cqlproxy-schema.yml run temporal-admin-tools -ep cql-proxy -k temporal update-schema -d schema/cassandra/temporal/versioned/
+
+docker-compose -f docker-compose-cqlproxy-schema.yml run temporal-admin-tools -ep cql-proxy -k temporal_visibility setup-schema -v 0.0
+docker-compose -f docker-compose-cqlproxy-schema.yml run temporal-admin-tools -ep cql-proxy -k temporal_visibility update-schema -d schema/cassandra/visibility/versioned/
+```
+
+* Start up Temporal!
+```sh
+docker-compose -f docker-compose-cqlproxy.yml up
+```
