 Please note that development is still heavily in progress, and I will break the database a lot until it's ready for prime time.

+
+Setup
+-----
+
+Add Jabit as Gradle dependency:
+```Gradle
+compile 'ch.dissem.jabit:jabit-domain:0.2.0'
+```
+Unless you want to implement your own, also add the following:
+```Gradle
+compile 'ch.dissem.jabit:jabit-networking:0.2.0'
+compile 'ch.dissem.jabit:jabit-repositories:0.2.0'
+```
+And if you want to import from or export to the Wallet Import Format (used by PyBitmessage) you might also want to add:
+```Gradle
+compile 'ch.dissem.jabit:jabit-wif:0.2.0'
+```
+
+Usage
+-----
+
+First, you'll need to create a `BitmessageContext`:
+```Java
+JdbcConfig jdbcConfig = new JdbcConfig();
+BitmessageContext ctx = new BitmessageContext.Builder()
+        .addressRepo(new JdbcAddressRepository(jdbcConfig))
+        .inventory(new JdbcInventory(jdbcConfig))
+        .messageRepo(new JdbcMessageRepository(jdbcConfig))
+        .nodeRegistry(new MemoryNodeRegistry())
+        .networkHandler(new NetworkNode())
+        .build();
+```
+This creates a simple context using a H2 database that will be created in the user's home directory. Next you'll need to
+start the context and decide what happens if a message arrives:
+```Java
+ctx.startup(new BitmessageContext.Listener() {
+    @Override
+    public void receive(Plaintext plaintext) {
+        // TODO: Notify the user
+    }
+});
+```
+Then you might want to create an identity
+```Java
+BitmessageAddress identity = ctx.createIdentity(false, Pubkey.Feature.DOES_ACK);
+```
+or add some contacts
+```Java
+BitmessageAddress contact = new BitmessageAddress("BM-2cTarrmjMdRicKZ4qQ8A13JhoR3Uq6Zh5j");
+address.setAlias("Chris");
+ctx.addContact(contact);
+```
+to which you can send some messages
+```Java
+ctx.send(identity, contact, "Test", "Hello Chris, this is a message.");
+```
