+# Repository construction
+
+Oak comes with a simple mechanism for constructing content repositories
+for use in embedded deployments and test cases. This article describes this
+mechanism. Deployments in managed enviroments like OSGi should use the native
+construction/configuration mechanism of the environment.
+
+The core class to use is called `Oak` and can be found in the
+`org.apache.jackrabbit.oak` package inside `oak-core`. It takes a
+`MicroKernel` instance and wraps it into a `ContentRepository`:
+
+    MicroKernel kernel = ...;
+    ContentRepository repository = new Oak(kernel).createContentRepository();
+
+For test purposes you can use the default constructor that
+automatically instantiates an in-memory `MicroKernel` for use with the
+repository. And if you're only using the test repository for a single
+`ContentSession` or just a singe `Root`, then you can shortcut the login
+steps by using either of the last two statements below:
+
+    ContentRepository repository = new Oak().createContentRepository();
+    ContentSession session = new Oak().createContentSession();
+    Root root = new Oak().createRoot();
+
+By default no pluggable components are associated with the created
+repository, so all login attempts will work and result in full write
+access. There's also no need to close the sessions or otherwise
+release acquired resources, as normal garbage collection will take
+care of everything.
+
+To add extra functionality like type validation or indexing support,
+use the `with()` method. The method takes all kinds of Oak plugins and
+adds them to the repository to be created. The method returns the Oak
+instance being used, so you can chain method calls like this:
+
+    ContentRepository repository = new Oak(kernel)
+        .with(new InitialContent())        // add initial content
+        .with(new DefaultTypeEditor())     // automatically set default types
+        .with(new NameValidatorProvider()) // allow only valid JCR names
+        .with(new SecurityProviderImpl())  // use the default security
+        .with(new PropertyIndexHook())     // simple indexing support
+        .with(new PropertyIndexProvider()) // search support for the indexes
+        .createContentRepository();
+
+As you can see, constructing a fully featured JCR repository like this
+will require quite a few plugins. To avoid having to specify them all
+whenever constructing a new repository, we also have a class called
+`Jcr` in the `org.apache.jakcrabbit.oak.jcr` package in `oak-jcr`. That
+class works much like the `Oak` class, but it constructs
+`javax.jcr.Repository` instances instead of `ContentRepositories` and
+automatically includes all the plugin components needed for proper JCR
+functionality:
+
+    MicroKernel kernel = ...;
+    Repository repository = new Jcr(kernel).createRepository();
+
+The `Jcr` class supports all the same `with()` methods as the `Oak` class
+does, so you can easily extend the constructed JCR repository with custom
+functionality if you like. For test purposes the `Jcr` class also has an
+empty default constructor that works like the one in the `Oak` class.
