To use the SharinPix Plan component, simply need to drag and drop the component from the Lightning App Builder onto your page layout.

SharinPix Plan Setting will be used to be able to determine the relationship between the object SharinPix Plan Item. The SharinPix Plan Item is the object which will save the annotations such as Marker, CircleMarker, Poloygon, Line, and Rectangle. 

Before you create the SharinPix Plan Setting, you need to create the relationship between your main object and the SharinPix Plan Item. Create a field of type lookup on the SharinPix Plan Item object. Save the field API name as it will be used for the configuration later. 

Steps to configure the SharinPix Plan Item:

1. Go to Salesforce Setup
2. Open Custom Metadata Types
3. Click on Manage Records for SharinPix Plan Setting Custom metadata type
4. Insert a label and name
5. Insert your object API name 
6. Insert the field API name of the field recently created on the SharinPix Plan Item
7. In the section Plan Item Setting, add a Default color.
8. Check Auto Number (if you want the auto numbering option to appear on the marker).

Once the plan setting has been configured, assign the permission set SharinPix Plan to all users needing access to the Plan component. This permission set gives users the necessary access to the SharinPix Plan Item object and fields.
