Required Modules

CRM declares seven module dependencies in crm.info.yml. Drupal will not enable CRM until all of them are present. Four are contrib modules pulled in by Composer; three are Drupal core modules enabled as part of the dependency chain.

Required modules

Module	Type	Role in CRM
Address	Contrib	address field on address contact methods
Datetime	Core	Contact start and end date fields
Image	Core	Contact profile image field
Telephone	Core	telephone field on telephone contact methods
Inline Entity Form	Contrib	Inline editing of contact methods and relationships on contact forms
Name	Contrib	Structured full_name field on person contacts
Primary Entity Reference	Contrib	Primary email, telephone, and address selection among multiples

Contrib module details

• Address — powers the address contact method bundle. See Contact Method.
• Inline Entity Form — embeds contact method and relationship editing on contact forms. Also used when syncing user profile fields with mapped contacts.
• Name — provides the structured name components on person contacts (given, family, and related subfields).
• Primary Entity Reference — marks one email, telephone, or address as primary when a contact has several of the same type.

Installation

Recommended path using Composer:

composer require drupal/crm
drush pm:enable crm -y

Composer installs the four contrib dependencies automatically. Drupal enables them when CRM is enabled through Extend or Drush.

If you install CRM from a tarball without Composer, you must also download and enable Address, Inline Entity Form, Name, and Primary Entity Reference before enabling CRM.
