 ###### One-to-Many Associations
-One-to-Many Associations are represented in OrientDB by a LINKSET.
+One-to-Many Associations are also represented by a LINK in OrienDB.
 
 ###### Many-to-Many Associations
-Many-to-Many Associations are handled by Waterline core, creating a join table holding foreign keys to the associated records. Waterline-orientdb does not change this behaviour for now but we will replace the join table by Edges in a future release ([#29](https://github.com/appscot/waterline-orientdb/issues/29)).

Currently it's not deemed a priority.
 
 ###### Many-to-Many Through Associations
-In Many-to-Many Through Association the join table is represented in OrientDB by Edges. Waterline-orientdb automatically creates the edges whenever an association is created. The Edge is named after the property tableName or identity in case tableName is missing.
+In a [Many-to-Many Through Association](https://github.com/balderdashy/waterline-docs/blob/master/associations.md#many-to-many-through-associations) ([more info](https://github.com/balderdashy/waterline/issues/705#issuecomment-60945411)) the join table is represented in OrientDB by Edges. Waterline-orientdb automatically creates the edges whenever an association is created. The Edge is named after the property tableName or identity in case tableName is missing.
 
 #### sails-orientdb differences
 
 ###### Edge creation
-The main difference between waterline-orientdb and [sails-orientdb](https://github.com/vjsrinath/sails-orientdb) is the way associations/edges are created. In `sails-orientdb` a special attribute named 'edge' is required while waterline-orientdb tries to adhere to waterline specficiation.

 ###### ID

+Waterline-orientdb mimics sails-mongo adapter behaviour and maps the logical `id` attribute to the required `@rid` physical-layer OrientDB Record ID. Because of this it's not necessary, or advised, to declare an `id` attribute on your model definitions.
 
 ## Usage
 
+#### Models
+
+`waterline-orientdb` uses the standard [waterline model definition](https://github.com/balderdashy/waterline-docs/blob/master/models.md) and extends it in order to accommodate OrientDB feature.
+
+###### orientdbClass
+
+It's possible to force the class of a model by adding the property `orientdbClass` to the definition. Generally this is not required as `waterline-orientdb` can determine which is the best class to use, so it should only be used in special cases. Possible values:
+* `""` or `"document"` - class will be the default OrientDB document class;
+* `"V"`- class will be Vertex;
+* `"E"`- class will be Edge.
+ 
+Example:
+```javascript
+{
+  identity : 'post',
+  orientdbClass : 'V'
+
+  attributes : {
+    name : 'string'
+  }
+}
+```
+
+Note, when using a document database (through `config.options.databaseType`), orientdbClass class will be ignored and all classes will be documents
+
+

 ## Overview
 
-#### Models
-Waterline-orientdb will represent most models in OrientDB as Vertices. The exception being Many-to-Many through join tables which are represented by Edges.
+### Models
+In a graph db Waterline-orientdb will represent most models in OrientDB as vertexes, the exception being Many-to-Many join tables which are represented by Edges. If using a document db, all models will be represented by documents.
 
-#### Associations
+### Associations
 To learn how to create associations with Waterline/Sails.js check the Waterline Docs [Associations Page](https://github.com/balderdashy/waterline-docs/blob/master/associations.md). Below we go through how waterline-orientdb approaches each kind of associations.
 
-###### One-to-One Associations
+#### One-to-One Associations
 For One-to-One Associations waterline-orientdb creates a LINK ([OrientDB Types](http://www.orientechnologies.com/docs/last/orientdb.wiki/Types.html)) to associate records.
 
-###### One-to-Many Associations
-One-to-Many Associations are also represented by a LINK in OrienDB.
+#### One-to-Many Associations
+One-to-Many Associations are also represented by LINKs in OrientDB.
 
-###### Many-to-Many Associations
-Many-to-Many Associations are handled by Waterline, creating a join table holding foreign keys to the associated records. Waterline-orientdb does not change this behaviour for now but we will replace the join table by Edges in a future release ([#29](https://github.com/appscot/waterline-orientdb/issues/29)). Currently it's not deemed a priority.
+#### Many-to-Many Associations
+In many-to-many associations waterline-orientdb will connect vertexes using edges, hence edges act as join tables. Usually Waterline will create rather long names for join tables (e.g. driver_taxis__taxi_drivers) which are little meaningful from the perspective of a graphDB. Waterline-orientdb allows you to change the name of the edge by adding a property `joinTableNames` to the dominant collection. Example:
+```javascript
+{
+  identity: 'driver',
+  joinTableNames: {
+    taxis: 'drives'
+  },
+  
+  attributes: {
+    name: 'string',
+    taxis: {
+      collection: 'taxi',
+      via: 'drivers',
+      dominant: true
+    }
+  }
+}
+```
+In this example the join table name **driver_taxis__taxi_drivers** get converted to **drives**. Complete example of the fixture can be found [here](https://github.com/appscot/waterline-orientdb/tree/master/test/integration-orientdb/fixtures/manyToMany.driverHack.fixture.js).
 
-###### Many-to-Many Through Associations
-In a [Many-to-Many Through Association](https://github.com/balderdashy/waterline-docs/blob/master/associations.md#many-to-many-through-associations) ([more info](https://github.com/balderdashy/waterline/issues/705#issuecomment-60945411)) the join table is represented in OrientDB by Edges. Waterline-orientdb automatically creates the edges whenever an association is created. The Edge is named after the property tableName or identity in case tableName is missing.

-###### Edge creation
+#### Edge creation
 The main difference between waterline-orientdb and [sails-orientdb](https://github.com/vjsrinath/sails-orientdb) is the way associations/edges are created. In `sails-orientdb` a special attribute named 'edge' is required while waterline-orientdb tries to adhere to waterline specification.
 
-###### ID
+#### ID
 Waterline-orientdb mimics sails-mongo adapter behaviour and maps the logical `id` attribute to the required `@rid` physical-layer OrientDB Record ID. Because of this it's not necessary, or advised, to declare an `id` attribute on your model definitions.
 
 ## Usage
 
-#### Models
+### Models
 
 `waterline-orientdb` uses the standard [waterline model definition](https://github.com/balderdashy/waterline-docs/blob/master/models.md) and extends it in order to accommodate OrientDB feature.
 
-###### orientdbClass
+#### orientdbClass
 
 It's possible to force the class of a model by adding the property `orientdbClass` to the definition. Generally this is not required as `waterline-orientdb` can determine which is the best class to use, so it should only be used in special cases. Possible values:
+* `undefined` - the default and recommended option. The appropriate class will be determined for the model;
 * `""` or `"document"` - class will be the default OrientDB document class;
 * `"V"`- class will be Vertex;
 * `"E"`- class will be Edge.

 #### Many-to-Many Through Associations
 In a [Many-to-Many Through Association](https://github.com/balderdashy/waterline-docs/blob/master/associations.md#many-to-many-through-associations) ([more info](https://github.com/balderdashy/waterline/issues/705#issuecomment-60945411)) the join table is represented in OrientDB by Edges. Waterline-orientdb automatically creates the edges whenever an association is created. The Edge is named after the property tableName (or identity in case tableName is missing).
 
+#### Populate queries (joins)
+Waterline-orientdb implements its own custom join function so when the user runs `.populate(some_collection)` it will send a single `SELECT` query with a [fetchplan](http://www.orientechnologies.com/docs/last/orientdb.wiki/Fetching-Strategies.html) to OrientDB. This way join operations remain fast and performant by leveraging OrientDB's graphDB features.

 The main difference between waterline-orientdb and [sails-orientdb](https://github.com/vjsrinath/sails-orientdb) is the way associations/edges are created. In `sails-orientdb` a special attribute named 'edge' is required while waterline-orientdb tries to adhere to waterline specification.

 It's possible to force the class of a model by adding the property `orientdbClass` to the definition. Generally this is not required as `waterline-orientdb` can determine which is the best class to use, so it should only be used in special cases. Possible values:
 * `undefined` - the default and recommended option. The appropriate class will be determined for the model;
 * `""` or `"document"` - class will be the default OrientDB document class;
-* `"V"`- class will be Vertex;
-* `"E"`- class will be Edge.
