+# Object API - Overview
+
+The object API provides methods for fetching domain objects.
+
+# Keys
+Keys are a composite identifier that is used to create and persist objects.  Ex:
+```javascript
+{
+    namespace: 'elastic',
+    identifier: 'myIdentifier'
+}
+```
+
+In old MCT days, we called this an "id", and we encoded it in a single string.  
+The above key would encode into the identifier, `elastic:myIdentifier`.
+
+When interacting with the API you will be dealing with key objects.
+
+# Configuring the Object API
+
+The following methods should be used before calling run.  They allow you to 
+configure the persistence space of MCT.
+
+* `MCT.objects.addRoot(key)` -- add a "ROOT" to Open MCT by specifying it's 
+    key.
+* `MCT.objects.removeRoot(key)` -- Remove a "ROOT" from Open MCT by key.
+* `MCT.objects.addProvider(namespace, provider)` -- register an object provider
+    for a specific namespace.  See below for documentation on the provider 
+    interface.
+    
+# Using the object API
+
+The object API provides methods for getting, saving, and deleting objects.
+
+* MCT.objects.get(key) -> returns promise for an object
+* MCT.objects.save(object) -> returns promise that is resolved when object
+    has been saved
+* MCT.objects.delete(object) -> returns promise that is resolved when object has 
+    been deleted
+
+## Configuration Example: Adding a groot
+
+The following example adds a new root object for groot and populates it with
+some pieces of groot.
+
+```javascript
+
+var ROOT_KEY = {
+    namespace: 'groot',
+    identifier: 'groot'
+};
+
+var GROOT_ROOT = {
+    name: 'I am groot',
+    type: 'folder',
+    composition: [
+        {
+            namespace: 'groot',
+            identifier: 'arms'
+        },
+        {
+            namespace: 'groot',
+            identifier: 'legs'
+        },
+        {
+            namespace: 'groot',
+            identifier: 'torso'
+        }
+    ]
+};
+
+var GrootProvider = {
+    get: function (key) {
+        if (key.identifier === 'groot') {
+            return Promise.resolve(GROOT_ROOT);
+        }
+        return Promise.resolve({
+            name: 'Groot\'s ' + key.identifier
+        });
+    }
+};
+
+mct.Objects.addRoot(ROOT_KEY);
+
+mct.Objects.addProvider('groot', GrootProvider);
+
+```
+
+### Making a custom provider:
+
+All methods on the provider interface are optional, so you do not need
+to modify them.
+
+* `provider.get(key)` -> promise for a domain object.
+* `provider.save(domainObject)` -> returns promise that is fulfilled when object 
+    has been saved.
+* `provider.delete(domainObject)` -> returns promise that is fulfilled when 
+    object has been deleted.
