 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 for local target
+1. Install requirements: 
 `sudo apt install gcc gcc-multilib cmake libssl-dev build-essential python3-dateparser`
-
-Install Rust from https://rustup.rs
-
-Reminder Bot can then 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.

-#### Compilation environment variables
-These environment variables must be provided when compiling the bot
+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**
+8. Build: `cargo build --release`
 
-### Setting up database
-Use MySQL 8. MariaDB is confirmed not working at the moment.
+### Compiling for other target
+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.
 
-Load the SQL files in order from "migrations" to generate the database schema.
+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` 
 
-### Setting up Python
-Reminder Bot uses `python3-dateparser` to handle dates. This depends on Python 3.
 
-### 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.
