 # AspNetCore.Identity.MongoDbCore
 A MongoDb UserStore and RoleStore adapter for Microsoft.AspNetCore.Identity 2.0.
 Allows you to use MongoDb instead of SQL server with Microsoft.AspNetCore.Identity 2.0.
+
 Covered by 737 integration tests and unit tests from the modified [Microsoft.AspNetCore.Identity.EntityFrameworkCore.Test](https://github.com/aspnet/Identity/tree/b865d5878623077eeb715e600d75fa9c24dbb5a1/test/Microsoft.AspNetCore.Identity.EntityFrameworkCore.Test) test suite.
 
 # Usage examples
 
-Your user and role entities must inherit from MongoIdentityUser<Guid> and MongoIdentityRole<TKey> in a way similar to the IdentityUser<TKey> and the IdentityRole<TKey> in Microsoft.AspNetCore.Identity.

+The `Id` field is automatically set at instanciation, this also applies to users inheriting from `MongoIdentityUser<int>`, where a random integer is assigned to the `Id`. It is however not advised to rely on such random mechanism to set the primary key of your document. Using documents inheriting from `MongoIdentityRole<Guid>` is recommended.
+
 The configuration is done by populating a `MongoDbIdentityConfiguration` object, which can have an `IdentityOptionsAction` property set to an action you want to perform against the `IdentityOptions` (`Action<IdentityOptions>`).
+
 The `MongoDbSettings` object is used to set MongoDb Settings using the `ConnectionString` and the `DatabaseName` properties.
 
 The MongoDb connection is managed using the [mongodb-generic-repository](https://github.com/alexandre-spieser/mongodb-generic-repository), where a repository inheriting `IBaseMongoRepository` is registered as a singleton. Look at the [ServiceCollectionExtension.cs](https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/blob/master/src/Extensions/ServiceCollectionExtension.cs) file for more details.
