-Treat PostgreSQL and SQLite as document stores from Java and Kotlin
\ No newline at end of file
+Treat PostgreSQL and SQLite as document stores from Java, Kotlin, Scala, and Groovy
+
+## Examples
+
+```java
+// Retrieve (find) all orders (Java)
+public List<Order> findOrders(Connection conn) {
+    Find.all(/*table name*/ "order", /*type*/ Order.class, conn);
+}
+```
+
+```kotlin
+// Mark an order as fulfilled (Kotlin)
+fun markFulfilled(orderId: Long, conn: Connection) =
+    conn.patchById(
+        /*table name*/ "order",
+        /*document ID*/ orderId,
+        /*patch object*/ mapOf("fulfilled" to true)
+    )
+```
+
+```scala
+// Delete orders marked as obsolete (Scala)
+def deleteObsolete(Connection conn):
+  conn.deleteByFields(/*table name*/ "order",
+    /*field criteria*/ Field.equal("obsolete", true) :: Nil)
+```
+
+```groovy
+// Remove the pending status from multiple orders (Groovy)
+void clearPending(List<Long> orderIds, Connection conn) {
+    conn.removeFieldsByFields(/*table name*/ "order",
+            /*field criteria*/ List.of(Field.any("id", orderIds)),
+            /*fields to remove*/ List.of("pending"))
+}
+```
+
+## Packages / Modules
+
+* The `core` module provides the base implementation and can be used from any JVM language.
+  * The `solutions.bitbadger.documents` package contains support types like `Configuration` and `Field`.
+  * The `solutions.bitbadger.documents.java` package contains document access functions and serialization config.
+  * The `solutions.bitbadger.documents.java.extensions` package contains extensions on the JDBC `Connection` object, callable as extension methods from Kotlin or as static functions from other languages.
+
+* The `groovy` module packages the extension methods so that Groovy can access them. No other packages will need to be imported; they will show up on any `Connection` instance.
+
+* The `kotlinx` module utilizes the kotlinx-serialization project for its JSON serialization, which requires a different serializer and different function/method signatures (`inline fun <reified T> ...` vs. `fun <T> ...`).
+  * `solutions.bitbadger.documents.kotlinx` and `solutions.bitbadger.documents.kotlinx.extensions` packages expose a similar API to their `java` counterparts, but one designed to be consumed from Kotlin. Generally, document retrieval functions will require a generic parameter instead of a `Class<T>` parameter.  
+
+* The `scala` module extends `core` by utilizing Scala's implicit `ClassTag`s to remove the `Class[T]` parameter.
+  * `solutions.bitbadger.documents.scala` and `solutions.bitbadger.documents.scala.extensions` packages expose the same API as their `java` counterparts, utilizing Scala collections and `Option`s instead of Java collections and `Optional`s.
