+.. warning::
+
+    Setting either of the ``LOG_<TYPE>_HANDLER`` variables to ``file`` requires the appropriate ``LOG_<TYPE>_FILE`` to be set
+
+Other environment variables
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+All other confguration options are parsed programatically from environment variables that are formatted differently for the two file types -- one way for the ``ini`` file and another for the ``.yml`` file.
+
+INI configuration file
+^^^^^^^^^^^^^^^^^^^^^^
+
+The environment variables that should be passed to the ``ldapcherry.ini`` configuration file are only to be made into upper-case underscore-separated versions of the options inside of each section of the ldapcherry.ini file. For instance:
+
+::
+
+  server.socket_host -> SERVER_SOCKET_HOST
+  request.show_tracebacks -> REQUEST_SHOW_TRACEBACKS
+  tools.sessions.timeout -> TOOLS_SESSIONS_TIMEOUT
+  min_length -> MIN_LENGTH
+
+They will be put into their respective sections in the ldapcherry.ini file.
+
+YAML configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+For the yaml configuration files (``attributes.yml`` and ``roles.yml``), the environment variable name is programatically parsed based on the following template:
+
+::
+
+  <FILENAME (without the .yml extension)>__<ATTRIBUTE ID>__<PARAMETER>
+
+The following example demonstrates how to customize the ``shell`` attribute ID in the ``attributes.yml`` file:
+
+::
+
+  shell:
+      description: "Shell of the user"
+      display_name: "Shell"
+      weight: 80
+      values:
+          - /bin/bash
+          - /bin/zsh
+          - /bin/sh
+
+::
+
+  ATTRIBUTES__SHELL__DESCRIPTION="Shell of the user"
+  ATTRIBUTES__SHELL__DISPLAY_NAME="Shell"
+  ATTRIBUTES__SHELL__WEIGHT="80"
+  ATTRIBUTES__SHELL__VALUES="['/bin/bash', '/bin/zsh', '/bin/sh']"
