-## 🧪 Getting Started (coming soon)
+## 🧪 Installation
 
-Instructions on installing dependencies, initializing the database, and running the bot locally will go here.
+1. Download and install dependencies
 
+Clone the repo
+
+```sh
+git clone https://git.waifuism.life/waifu/kemoverse.git
+cd kemoverse
+```
+
+Setup a virtual environment (Optional, recommended)
+
+```sh
+python3 -m venv venv
+source venv/bin/activate
+```
+
+Install project dependencies via pip
+
+```sh
+python3 -m pip install -r requirements.txt
+```
+
+2. Setup config file
+
+A sample config file is included with the project as a template: `example_config.ini`
+
+Create a copy of this file and replace its' values with your own. Consult the
+template for more information about individual config values and their meaning.
+
+Config files are environment-specific. Use `config_dev.ini` for development and
+`config_prod.ini` for production. Switch between environments using the
+`KEMOVERSE_ENV` environment variable.
+
+```sh
+cp example_config.ini config_dev.ini
+# Edit config_dev.ini
+```
+
+4. Setup database
+
+To set up the database, run:
+
+```sh
+KEMOVERSE_ENV=dev python3 setup_db.py
+```
+
+5. Run the bot
+
+```sh
+KEMOVERSE_ENV=dev ./startup.sh
+```
+
+If all goes well, you should now be able to interact with the bot.
+
+6. Running in production
+
+To run the the in a production environment, use `KEMOVERSE_ENV=prod`. You will
+also need to create a `config_prod.ini` file and run the database setup step
+again if pointing prod to a different database. (you are pointing dev and prod
+to different databases, right? 🤨)
+
+7. Updating
+
+To update the bot, first pull new changes from upstream:
+
+```sh
+git pull
+```
+
+Then run any database migrations. We recommend testing in dev beforehand to
+make sure nothing breaks in the update process.
+
+**Always backup your prod database before running any migrations!**
+
+```sh
+# Backup database file
+cp gacha_game_dev.db gacha_game_dev.db.bak
+# Run migrations
+KEMOVERSE_ENV=dev python3 setup_db.py
+```
