 Flask-based web interface for user token adminstration of our hackerspace's door lock.
 
+## Installation
+Clone the repo
+```shell
+git clone <path_to_repo>
+```
+Install using pip
+```shell
+pip install .
+```
 
-# Development
+## Running the app
+```shell
+export FLASK_APP=imaginaerraum_door_admin
+flask run
+```
+
+## Configuration
+You can set custom configuration options by defining an environment variable
+``APPLICATION_SETTINGS`` pointing to a file with configuration options.
+
+For example, consider the following configuration file ``app_config.py``:
+```
+# door app configuration
+SECRET_KEY = 'mysupersecretkey'
+SECURITY_PASSWORD_SALT = 'saltycaramel'
+
+TESTING = False
+DEBUG = False
+
+TOKEN_FILE = 'door_tokens.txt'
+ADMIN_FILE = 'admins.txt'
+
+NFC_SOCKET = "/tmp/nfc.sock"
+NFC_LOG = "nfc.log"
+```
+To instruct the flask app to use this configuration, use the following commands:
+```shell
+export APPLICATION_SETTINGS=app_config.py
+flask run
+```
+
+Below, you can find a list of configuration options.
+
+### Flask app configuration
+You can override common Flask configuration variables. In particular, you 
+definitely should set custom values for the ``SECRET_KEY`` and 
+``SECURITY_PASSWORD_SALT``.
+
+### Token file
+The token file is an ASCII file which list the IDs of RFID tokens that can be
+used to unlock the door. You can specify the path to the token file using the
+``TOKEN_FILE`` variable in the configuration file.
+Here's an example of a token file (lines starting with ``#`` represent inactive
+tokens):
+```
+# token | name | organization | email | valid_thru
+#042979fa186280||||
+04487cfa176280|Frodo|Hobbits|frodo@shire.me|
+043a85fa1a6280|Gandalf|Wizards|gandalf@middleearth.me|
+#04206e2aef6880|Boromir|Humans|boromir@gondor.me|
+```
+
+### Admin file
+``ADMIN_FILE`` -> file to create new super admins
+
+### User database
+
+### NFC files
+``NFC_SOCKET = "/tmp/nfc.sock"`` -> unix socket to interact with the door
+``NFC_LOG = "nfc.log"`` -> log file of door events
+
+## Development
 ```shell
 cd tests
 export APPLICATION_SETTINGS=/home/simon/imaginaerraum/door-lock/webinterface/tests/debug_app_config.py
