 Testcontainers can run an init script after the database container is started, but before your code is given a connection to it. The script must be on the classpath, and is referenced as follows:

+# Presto Module
+
+!!! note
+    This module is INCUBATING. While it is ready for use and operational in the current version of Testcontainers, it is possible that it may receive breaking changes in the future. See [our contributing guidelines](/contributing/#incubating-modules) for more information on our incubating modules policy.
+
+See [Database containers](./index.md) for documentation and usage that is common to all database container types.
+
+## Usage example
+
+Running Presto as a stand-in for in a test:
+
+```java
+public class SomeTest {
+
+    @Rule
+    public PrestoContainer presto = new PrestoContainer();
+
+    @Test
+    public void someTestMethod() {
+        String url = presto.getJdbcUrl();
+
+        ... create a connection and run test as normal
+```
+
+Presto comes with several catalogs preconfigured. Most useful ones for testing are
+
+* `tpch` catalog using the [Presto TPCH Connector](https://prestosql.io/docs/current/connector/tpch.html).
+  This is a read-only catalog that defines standard TPCH schema, so is available for querying without a need
+  to create any tables.
+* `memory` catalog using the [Presto Memory Connector](https://prestosql.io/docs/current/connector/memory.html).
+  This catalog can be used for creating schemas and tables and does not require any storage, as everything
+  is stored fully in-memory.
+
+Example test using the `tpch` and `memory` catalogs:
+
+```java
+public class SomeTest {
+    @Rule
+    public PrestoContainer prestoSql = new PrestoContainer();
+
+    @Test
+    public void queryMemoryAndTpchConnectors() throws SQLException {
+        try (Connection connection = prestoSql.createConnection();
+             Statement statement = connection.createStatement()) {
+            // Prepare data
+            statement.execute("CREATE TABLE memory.default.table_with_array AS SELECT 1 id, ARRAY[1, 42, 2, 42, 4, 42] my_array");
+
+            // Query Presto using newly created table and a builtin connector
+            try (ResultSet resultSet = statement.executeQuery("" +
+                "SELECT nationkey, element " +
+                "FROM tpch.tiny.nation " +
+                "JOIN memory.default.table_with_array twa ON nationkey = twa.id " +
+                "LEFT JOIN UNNEST(my_array) a(element) ON true " +
+                "ORDER BY element OFFSET 1 FETCH NEXT 3 ROWS WITH TIES ")) {
+                List<Integer> actualElements = new ArrayList<>();
+                while (resultSet.next()) {
+                    actualElements.add(resultSet.getInt("element"));
+                }
+                Assert.assertEquals(Arrays.asList(2, 4, 42, 42, 42), actualElements);
+            }
+        }
+    }
+}
+```
+
+## Adding this module to your project dependencies
+
+Add the following dependency to your `pom.xml`/`build.gradle` file:
+
+```groovy tab='Gradle'
+testCompile "org.testcontainers:presto:{{latest_version}}"
+```
+
+```xml tab='Maven'
+<dependency>
+    <groupId>org.testcontainers</groupId>
+    <artifactId>presto</artifactId>
+    <version>{{latest_version}}</version>
+    <scope>test</scope>
+</dependency>
+```
+
+!!! hint
+    Adding this Testcontainers library JAR will not automatically add the Presto JDBC driver JAR to your project.
+    You should ensure that your project has the Presto JDBC driver as a dependency, if you plan on using it.
+    Refer to [Presto project download page](https://prestosql.io/download.html) for instructions.
