+## Application Factory Interface Structure
+
+1. [Interface structure](#interface-structure)
+1. [Classic](#classic), a backwards compatible implementation 
+1. Dependency Injection, a dynamic factory that can be configured instead of using hard reference maps
+
+### Interface structure
+The existing Application factories of the 
+[apex-commons](https://github.com/apex-enterprise-patterns/fflib-apex-common)
+do not have interfaces, therefore it is hard to replace their implementations. The fflib-apex-extensions add an interface structure and includes multiple implementations for you to choose from.
+
+The [classic](#classic) implementation is fully backward compatible and in the well known familiar structure.
+
+The interfaces adds the following added features
+
+- fflib_IServiceFactory
+    - [replaceWith](#fflib_iservicefactory---replacewith)
+- fflib_ISelectorFactory
+    - [selectById](#fflib_iselectorfactory---selectbyid) _(method overload)_
+    - [replaceWith](#fflib_iselectorfactory---replacewith)
+    - [setMock](#fflib_iselectorfactory---setmock) _(method overload)_
+- fflib_IDomainFactory
+    - [newInstance](#fflib_idomainfactory---newinstance) _(method overload)_
+    - [replaceWith](#fflib_idomainfactory---replacewith)
+    - [setMock](#fflib_idomainfactory---setmock) _(method overload)_
+
+
+##### fflib_IServiceFactory - replaceWith
+This will create or replaces an existing binding for another.
+
+###### Syntax
+`void replaceWith(Type serviceInterfaceType, Type replacementImplType)`
+
+###### Example
+Let's assume we have two implementation for AccountsService `AccountsServiceImpl` and `AlternativeAccountsServiceImpl`.
+In the Service Factory `IAccountsService` is bound to the `AccountsServiceImpl` implementation.
+```apex
+IAccountsService accountsService = (IAccountsService) Application.Service.newInstance();
+System.assert(accountsService instanceof AccountsServiceImpl);
+
+// Replace the implementation binding
+Application.Service.replaceWith(IAccountsService.class, MyAlternateAccountsServiceImpl.class);
+
+IAccountsService accountsService = (IAccountsService) Application.Service.newInstance();
+System.assert(accountsService instanceof AlternativeAccountsServiceImpl);
+```
+
+##### fflib_ISelectorFactory - selectById
+This method overload accepts an extra argument named `sObjectType`. 
+By providing the SObjectType, the method assumes that all the provided Ids are of the given SObjectType.
+Thereby executing faster as the original method doesn't need to iterate over all the ids 
+to validate that they are all from the same SObjectType.
+
+###### Syntax
+`List<SObject> selectById(Set<Id> recordIds, SObjectType sObjectType)`
+
+##### fflib_ISelectorFactory - replaceWith
+This will create or replaces an existing binding for another.
+
+###### Syntax
+`void replaceWith(SObjectType sObjectType, Type replacementImplType)`
+
+##### fflib_ISelectorFactory - setMock
+This method overload avoids the need to stub the selector mock to return its SObjectType
+
+###### Syntax
+`void setMock(SObjectType sObjectType, fflib_ISObjectSelector selectorInstance)`
+
+###### Example
+Instead of doing this:
+```apex
+fflib_ApexMocks mocks = new fflib_ApexMocks();
+AccountsSelector serviceMock = (AccountsSelector) mocks.mock(AccountsSelector.class);
+mocks.startStubbing();
+mocks.when(selectorMock.sObjectType()).thenReturn(Schema.Account.SObjectType);
+mocks.stopStubbing();
+Application.Selector.setMock(serviceMock);
+```
+You can now do the same without the need to stub it:
+```apex
+fflib_ApexMocks mocks = new fflib_ApexMocks();
+AccountsSelector serviceMock = (AccountsSelector) mocks.mock(AccountsSelector.class);
+Application.Selector.setMock(Schema.Account.SObjectType, serviceMock);
+```
+
+##### fflib_IDomainFactory - newInstance
+The added argument `sObjectType` avoids the selector to iterate over the given record Ids to validate them.
+
+###### Syntax
+`fflib_IDomain newInstance(Set<Id> recordIds, Schema.SObjectType sObjectType)`
+
+##### fflib_IDomainFactory - replaceWith
+This will create or replaces an existing binding for another.
+###### Syntax
+`void replaceWith(Schema.SObjectType sObjectType, Type replacementImplType)`
+
+##### fflib_IDomainFactory - setMock
+This method overload avoids the need to stub the selector mock to return its SObjectType
+
+###### Syntax
+`void setMock(Schema.SObjectType sObjectType, fflib_ISObjectDomain mockDomain)`
+
+###### Example
+Instead of doing this:
+```apex
+fflib_ApexMocks mocks = new fflib_ApexMocks();
+IAccounts domainMock = (IAccounts) mocks.mock(IAccounts.class);
+mocks.startStubbing();
+mocks.when(domainMock.getType()).thenReturn(Schema.Account.SObjectType);
+mocks.stopStubbing();
+Application.Domain.setMock(domainMock);
+```
+You can now do the same without the need to stub it:
+```apex
+fflib_ApexMocks mocks = new fflib_ApexMocks();
+IAccounts domainMock = (IAccounts) mocks.mock(IAccounts.class);
+Application.Domain.setMock(Schema.Account.SObjectType, domainMock);
+```
+
+### Classic
+This is the implementation you are looking for when you are used to the 
+[Application Factories](https://github.com/apex-enterprise-patterns/fflib-apex-common/blob/master/sfdx-source/apex-common/main/classes/fflib_Application.cls) 
+of the 
+[apex-commons](https://github.com/apex-enterprise-patterns/fflib-apex-common)
+and you do not want to change anything about the structure based on maps, 
+but do like to use the added features of fflib-apex-extensions.
+
+It is fully backwards compatible, and you only need to make a few small changes to your existing Application class, to use the added features.
+
+#### Application Class
+The Application class is slightly different than the stafactories in the fflib_Application are replaced by an interface structure.
+To use the backwards compatible version of the factories, change your Application class into the example below.
+Pay special attention to the interface types and implementation classes of the factories.
+
+**Example**
+```apex
+public class Application
+{
+    public static final fflib_IUnitOfWorkFactory UnitOfWork =
