 ---------------------------
 
 Now it's time to set up your environment. This is done by through the use of a
-:code:`dotenv` file.

+:code:`dotenv` file.
+
+In the root directory of the project, you can find a :code:`.env.sample` file. It's strongly recommended that you use this as a starting point:
+
+::
+
+  cp .env.sample .env
+
+Inside of this file you will find a number of environment variables:
+
+* :code:`FLASK_CONFIG=` A choice between :code:`deployment` and :code:`production`. :code:`production` disables debugging and stops SQLAlchemy spamming the console.
+* :code:`POSTGRES_USER=` The username of your PostgreSQL user. If you are using the :code:`docker-compose` file then this will be used within the :code:`db` container.
+* :code:`POSTGRES_PASSWORD=` The password of your PostgreSQL user. If you are using the :code:`docker-compose` file then this will be used within the :code:`db` container.
+* :code:`POSTGRES_HOST=` The database host address of your PostgreSQL server. If you are deploying the project through :code:`docker-compose` then ensure that the name matches what is found within the :code:`docker-compose.yml` file (this is usually :code:`db`).
+* :code:`POSTGRES_DB=` The database name for of your PostgreSQL server. If you are deploying the project through :code:`docker-compose` then ensure that the name matches what is found within the :code:`docker-compose.yml` file (this is usually :code:`limbus`).
+* :code:`SECRET_KEY=` A secret key to protect you against XSS. Please change this.
+* :code:`WTF_CSRF_SECRET_KEY=` A secret key to protect forms against XSS. Please change this.
+* :code:`DOCUMENT_DIRECTORY=` Where you want your encrypted document store to be located. If you are using the :code:`docker-compose` file, then please ensure that you mount your location appropriately.
+* :code:`TEMPLATES_DIRECTORY=` Where you want your templates store to be located. If you are using the :code:`docker-compose` file, then please ensure that you mount your location appropriately.
+* :code:`DEBUG=` If you require debug information. In most deployments this should be set to False.
+* :code:`DOID_PATH=` Where you want your DOID file to be located. If you are using the :code:`docker-compose` file, then please ensure that you mount your location appropriately.
+
+
+.. note::
+   Please ensure that all secret keys and passwords are secure.
