 ## Initializing database
 The first time you install the app in each environment, you need to initialize database using `flask --app flaskr init-db`. This only needs to be run once per environment, and **will delete existing database if run again**.
 
-## Secret key
+## Config file
+
+The config file is located at `<python_environment>/var/flaskr-instance/config.py` in production, and in `instance/` in development. The instance folder is created when the database is initialized.
+
+### Secret Key
 Every website with login needs a secret key to hash passwords with.
-`<python_environment>/var/flaskr-instance/config.py` must contain a line `SECRET_KEY = '<secret_key>`, which must be randomly generated.  
+The config file must contain a line `SECRET_KEY = '<secret_key>`, which must be randomly generated.  
 Suggested way of generating the key is `python -c 'import secrets; print(secrets.token_hex())'`, which returns a hexadecimal string with length 64. You may choose to randomly generate a key using a different method, but ensure that it is resistant to brute-force attacks.
+
+### Registration
+Since this blog is meant to be updated by a limited number of people, registration is forbidden (403) by default. In addition, registration (/auth/register) and login (/auth/login) URLs are not hyperlinked anywhere. Registration can be opened by including `REGISTER = True`, and is closed by default.
+
+### Name
+The default app name is "Flaskr", and it is visible on the header bar as well as the page title. Including a line `NAME = '<name>'` in the config file replaces "Flaskr" with your chosen name.
+
+### Static folder
+The default static folder is the one included in the repository. You can use a separate static folder to use your own assets by including a line `STATIC_FOLDER = '<absolute/path/to/folder>'` in the config file.
