 These environment variables must be provided when compiling the bot
 * `DATABASE_URL` - the URL of your MySQL database (`mysql://user[:password]@domain/database`)
 * `WEBHOOK_AVATAR` - accepts the name of an image file located in `$CARGO_MANIFEST_DIR/assets/` to be used as the avatar when creating webhooks. **IMPORTANT: image file must be 128x128 or smaller in size**
-* `STRINGS_FILE` - accepts the name of a compiled strings file located in `$CARGO_MANIFEST_DIR/assets/` to be used for creating messages. Compiled string files can be generated with `compile.py` at https://github.com/reminder-bot/languages
 
 ### Setting up Python
 Reminder Bot by default looks for a venv within it's working directory to run Python out of. To set up a venv, install `python3-venv` and run `python3 -m venv venv`. Then, run `source venv/bin/activate` to activate the venv, and do `pip install dateparser` to install the required library

 __Other Variables__
 * `MIN_INTERVAL` - default `600`, defines the shortest interval the bot should accept
-* `MAX_TIME` - default `1576800000`, defines the maximum time ahead that reminders can be set for
 * `LOCAL_TIMEZONE` - default `UTC`, necessary for calculations in the natural language processor
-* `DEFAULT_PREFIX` - default `$`, used for the default prefix on new guilds
 * `SUBSCRIPTION_ROLES` - default `None`, accepts a list of Discord role IDs that are given to subscribed users
 * `CNC_GUILD` - default `None`, accepts a single Discord guild ID for the server that the subscription roles belong to
 * `IGNORE_BOTS` - default `1`, if `1`, Reminder Bot will ignore all other bots
 * `PYTHON_LOCATION` - default `venv/bin/python3`. Can be changed if your Python executable is located somewhere else
-* `LOCAL_LANGUAGE` - default `EN`. Specifies the string set to fall back to if a string cannot be found (and to be used with new users)
 * `THEME_COLOR` - default `8fb677`. Specifies the hex value of the color to use on info message embeds 
-* `CASE_INSENSITIVE` - default `1`, if `1`, commands will be treated with case insensitivity (so both `$help` and `$HELP` will work)
 * `SHARD_COUNT` - default `None`, accepts the number of shards that are being ran
 * `SHARD_RANGE` - default `None`, if `SHARD_COUNT` is specified, specifies what range of shards to start on this process 
 * `DM_ENABLED` - default `1`, if `1`, Reminder Bot will respond to direct messages
