**What types of Content Requests are supported?**

Before making any request, please read the guidance on submitting content -

The new CRS tool features a variety of templates and two request entry modes to appeal to most users. These Include:

* **Create a new Concept(s)**

A request for a new concept must take into account existing content and align with the existing Editorial Guidance

* **Add New Synonym(s)**

A new synonym may be added to an existing concept if the request aligns with existing Editorial Guidance and has a clear justification.

* **Add or Modify Parent(s)**

A new parent may be added to an existing concept (or changed) if the request aligns with existing Editorial Guidance and has a clear justification.

* **Add or Modify Description(s)**

A new description may be added to an existing concept (or changed) if the request aligns with existing Editorial Guidance and has a clear justification.

* **Inactivate Concept(s), Description(s), or Relationship(s)**

Concepts or their components may be inactivated if the request aligns with existing Editorial Guidance and has a clear justification.

* **Modify and Create New Relationship(s)**

New relationships or modification to existing concepts may be made if the request aligns with existing Editorial Guidance and has a clear justification.
