+# Sample Docker File
+
+It can be difficult to test h3-presto if you don't have a Presto server running already. These instructions help you get a Presto node with h3-presto running for development. (These instructions are based on the [Presto Docker deployment](https://prestodb.io/docs/current/installation/deployment.html#an-example-deployment-with-docker) instructions.)
+
+To build, starting from the root of the repository:
+
+```sh
+mvn clean package -DskipTests
+cd contrib/docker
+cp ../../target/h3-presto-4.0.0.jar plugin/h3/h3-presto-4.0.0.jar
+docker build -f Dockerfile -t presto --build-arg PRESTO_VERSION=0.286 .
+```
+
+To run:
+
+```sh
+docker run -p 8080:8080 --rm -it presto
+```
+
+And then in another terminal, run the [Presto command line interface](https://prestodb.io/docs/current/installation/cli.html):
+
+```sh
+./presto
+```
+
+And try a sample query:
+
+```sql
+select h3_latlng_to_cell(0,0,0);
+```
