+#### Custom schema
+every .ldif or .sh file will be evaluated on server startup, if it's placed
+inside the '/docker-entrypoint-initdb.d/' directory. This allows you to
+Specify custom behaviour of the LDAP Server.
+
+By default the server will load the schema from the 'fixtures/' directory,
+which will provide this features:
+
+ * MDB backend for better performance
+ * Indexing of most referenced attributes by default
+ * Base structure with People, Groups, Sevices, Domains and Policies.
+ * Simple but useful ACL rules, allowing users to change their own passwords.
+ * Password policy for strong cryptographic hashing of user passwords and password rotation.
+ * Referential integrity for e.g. group memberships.
+ * Support for core, cosine, nis, inetorgperson, ppolicy and misc schemas.
+ * Support for user-definable SSH public keys as attributes.
+ * enforcing of username and user ID uniqueness.
+
+### Configuration
+The LDAP server can be configured for your organization using the environment variables:
+ * `ROOTPW` password for the administration user that is created by default. Make this hard to guess!
+ * `ORGANIZATION` Name of the organization running this LDAP server.
+ * `SUFFIX` overwrites the root node for all entries. By default this will be 'o=organizationname', but for compatibility you might want to set this to 'dc=domain,dc=tld'.
+ * `DATADIR` is the path to the directory containing the LDAP DATA; by default this is '/var/lib/ldap/'.
+ * `CONFDIR` points to the path containing the server configuration, by default this is '/etc/ldap/slapd.d'.
+
 ### Backing up data
 State stored in this container is essential to many other services, that
 use authentication and authorization. Therefore you should think about
