+I offer a hosted version of the bot. You can invite it with: **https://invite.reminder-bot.com**. The catch is that repeating 
 reminders are paid on the hosted version of the bot. Keep reading if you want to host it yourself.
 
 You'll need rustc and cargo for compilation. To run, you'll need Python 3 still (due to no suitable replacement for dateparser in Rust)
 
-### Compiling
-Reminder Bot can be built by running `cargo build --release` in the top level directory. It is necessary to create a folder called 'assets' containing an image file with its name specified in the environment as `WEBHOOK_AVATAR`, of dimensions 128x128px to be used as the webhook avatar.
+### Build APT package
 
-#### Compilation environment variables
-These environment variables must be provided when compiling the bot
+Recommended method.
+
+By default, this builds targeting Ubuntu 20.04. Modify the Containerfile if you wish to target a different platform. These instructions are written using `podman`, but `docker` should work too.
+
+1. Install container software: `sudo apt install podman`.
+2. Install database server: `sudo apt install mysql-server-8.0`. Create a database called `reminders`
+3. Install SQLx CLI: `cargo install sqlx-cli`
+4. From the source code directory, execute `sqlx migrate run`
+5. Build container image: `podman build -t reminder-rs .`
+6. Build with podman: `podman run --rm --network=host -v "$PWD":/mnt -w /mnt -e "DATABASE_URL=mysql://user@localhost/reminders" reminder-rs cargo deb` 
+
+
+### Compiling for other target
+
+1. Install requirements: 
+`sudo apt install gcc gcc-multilib cmake libssl-dev build-essential python3-dateparser`
+2. Install rustup from https://rustup.rs
+3. Install the nightly toolchain: `rustup toolchain default nightly`
+4. Install database server: `sudo apt install mysql-server-8.0`. Create a database called `reminders`.
+5. Install `sqlx-cli`: `cargo install sqlx-cli`.
+6. Run migrations: `sqlx migrate run`.
+7. Set environment variables:
    * `DATABASE_URL` - the URL of your MySQL database (`mysql://user[:password]@domain/database`)
-* `WEBHOOK_AVATAR` - accepts the name of an image file located in `$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
+8. Build: `cargo build --release`
 
-### 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
 
-### Environment Variables
+### Configuring
+
 Reminder Bot reads a number of environment variables. Some are essential, and others have hardcoded fallbacks. Environment variables can be loaded from a .env file in the working directory.
 
 __Required Variables__
@@ -29,16 +45,8 @@ __Required Variables__
 
 __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 `$`, used for the default prefix on new guilds
 * `SUBSCRIPTION_ROLES` - default `None`, accepts a list of Discord role IDs that are given to subscribed users
 * `CNC_GUILD` - default `None`, accepts a single Discord guild ID for the server that the subscription roles belong to
-* `IGNORE_BOTS` - default `1`, if `1`, Reminder Bot will ignore all other bots
-* `PYTHON_LOCATION` - default `venv/bin/python3`. Can be changed if your Python executable is located somewhere else
-* `LOCAL_LANGUAGE` - default `EN`. Specifies the string set to fall back to if a string cannot be found (and to be used with new users)
+* `PYTHON_LOCATION` - default `/usr/bin/python3`. Can be changed if your Python executable is located somewhere else
 * `THEME_COLOR` - default `8fb677`. Specifies the hex value of the color to use on info message embeds 
-* `CASE_INSENSITIVE` - default `1`, if `1`, commands will be treated with case insensitivity (so both `$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
