+ * Top-level {@link org.apache.beam.sdk.transforms.PTransform}s that build and
instantiate turnkey
+ * transforms.
+ *
+ * <h3>Available transforms</h3>
+ *
+ * <p>This API currently supports two operations: {@link Read} and {@link
Write}. Each one
+ * enumerates the available transforms in a {@code TRANSFORMS} map.
+ *
+ * <h3>Building a Managed turnkey transform</h3>
+ *
+ * <p>Turnkey transforms are represented as {@link SchemaTransform}s, which
means each one has a
+ * defined configuration. A given transform can be built with a {@code
Map<String, Object>} that
+ * specifies arguments using like so:
+ *
+ * <pre>{@code
+ * PCollectionRowTuple output = PCollectionRowTuple.empty(pipeline).apply(
+ * Managed.read(ICEBERG)
+ * .withConfig(ImmutableMap.<String, Map>.builder()
+ * .put("foo", "abc")
+ * .put("bar", 123)
+ * .build()));
+ * }</pre>
+ *
+ * <p>Instead of specifying configuration arguments directly in the code, one
can provide the
+ * location to a YAML file that contains this information. Say we have the
following YAML file:
+ *
+ * <pre>{@code
+ * foo: "abc"
+ * bar: 123
+ * }</pre>
+ *
+ * <p>The file's path can be passed in to the Managed API like so:
+ *
+ * <pre>{@code
+ * PCollectionRowTuple input = PCollectionRowTuple.of("input",
pipeline.apply(Create.of(...)))
+ *
+ * PCollectionRowTuple output = input.apply(
+ * Managed.write(ICEBERG)
+ * .withConfigUrl(<config path>));
