+# Access Control Systems
+
+## Resources
+
+### [`acs_system`](./systems/README.md#acs_system)
+Represents an [access control system](https://docs.seam.co/latest/capability-guides/access-systems).
+
+### [`acs_user`](./users/README.md#acs_user)
+
+
+### [`acs_entrance`](./entrances/README.md#acs_entrance)
+Represents an [entrance](../../capability-guides/access-systems/retrieving-entrance-details.md) within an [access control system](https://docs.seam.co/latest/capability-guides/access-systems).
+
+### [`acs_access_group`](./access_groups/README.md#acs_access_group)
+Group that defines the entrances to which a set of users has access and, in some cases, the access schedule for these entrances and users.
+The `acs_access_group` object represents an [access group](https://docs.seam.co/latest/capability-guides/access-systems/assigning-users-to-access-groups) within an [access control system](https://docs.seam.co/latest/capability-guides/access-systems).
+
+### [`acs_credential`](./credentials/README.md#acs_credential)
+Means by which a user gains access at an entrance.
+The `acs_credential` object represents a credential that provides an ACS user access within an access control system. For each acs_credential object, you define the access method. You can also specify additional properties, such as a code.
