+### Components
+
+User defined fields can be configured one of two ways: At the application level, or at the model level.
+
+##### Application Level
+If configured at the application level, each record in the specified table will contain the same user defined fields.
+
+For example: You could define `first_name` and `last_name` fields for all of the `people` records. Anytime a user is editing a a person form, the `first_name` and `last_name` fields will be available as inputs.
+
+```jsx
+<UserDefinedFieldsList />
+```
+
+##### Model Level
+If configured at the model level, records can contain different fields dependent on a parent record.
+
+For example: You could define a `location` field for `resources` that belong to Project A, then define a `project_stage` field for `resources` that belong to Project B. On the edit for for Project A, only the `location` field will be available. On the edit form for Project B, only the `project_stage` field will be available.
+
+```jsx
+<UserDefinedFieldsEmbeddedList
+  items={props.item.user_defined_fields}
+  onDelete={props.onDeleteChildAssociation.bind(this, 'user_defined_fields')}
+  onSave={props.onSaveChildAssociation.bind(this, 'user_defined_fields')}
+/>
