+## Organization Unit Management
+
+Organization units (OU) is a part of **Identity Module** and can be used to **hierarchically group users and entities**. 
+
+### OrganizationUnit Entity
+
+An OU is represented by the **OrganizationUnit** entity. The fundamental properties of this entity are:
+
+- **TenantId**: Tenant's Id of this OU. Can be null for host OUs.
+- **ParentId**: Parent OU's Id. Can be null if this is a root OU.
+- **Code**: A hierarchical string code that is unique for a tenant.
+- **DisplayName**: Shown name of the OU.
+
+The OrganizationUnit entity's primary key (Id) is a **Guid** type and it derives from the [**FullAuditedAggregateRoot**](../Entities.md) class.
+
+#### Organization Tree
+
+Since an OU can have a parent, all OUs of a tenant are in a **tree** structure. There are some rules for this tree;
+
+- There can be more than one root (where the `ParentId` is `null`).
+- There is a limit for the first-level children count of an OU (because of the fixed OU Code unit length explained below).
+
+#### OU Code
+
+OU code is automatically generated and maintained by the OrganizationUnit Manager. It's a string that looks something like this:
+
+"**00001.00042.00005**"
+
+This code can be used to easily query the database for all the children of an OU (recursively). There are some rules for this code:
+
+- It must be **unique** for a [tenant](../Multi-Tenancy.md).
+- All the children of the same OU have codes that **start with the parent OU's code**.
+- It's **fixed length** and based on the level of the OU in the tree, as shown in the sample.
+- While the OU code is unique, it can be **changeable** if you move an OU.
+- You must reference an OU by Id, not Code.
+
+### OrganizationUnit Manager
+
+The **OrganizationUnitManager** class can be [injected](../Dependency-Injection.md) and used to manage OUs. Common use cases are:
+
+- Create, Update or Delete an OU
+- Move an OU in the OU tree.
+- Getting information about the OU tree and its items.
+
+#### Multi-Tenancy
+
+The `OrganizationUnitManager` is designed to work for a **single tenant** at a time. It works for the **current tenant** by default.
