+# TomodachiShare Development Instructions
+
+Welcome to the TomodachiShare development guide! This project uses [pnpm](https://pnpm.io/) for package management, [Next.js](https://nextjs.org/) with the app router for the front-end and back-end, [Prisma](https://prisma.io) for the database, [TailwindCSS](https://tailwindcss.com/) for styling, and [TypeScript](https://www.typescriptlang.org/) for type safety.
+
+## Getting started
+
+To get the project up and running locally, follow these steps:
+
+```bash
+$ git clone https://github.com/trafficlunar/tomodachi-share
+$ cd tomodachi-share
+$ pnpm install
+```
+
+Prisma types are generated automatically post-install, which is quite convenient. However, sometimes you might need to:
+
+```bash
+# Generate Prisma client types
+$ pnpm prisma generate
+
+# Or, if you've added new database properties
+$ pnpm prisma migrate dev
+$ pnpm prisma generate
+```
+
+## Environment variables
+
+You'll need a PostgreSQL database and Redis database. I would recommend using [Docker](https://www.docker.com/) to set these up quickly. Just create a `docker-compose.yaml` with the following content and run `docker compose up -d`:
+
+```yaml
+services:
+  db:
+    image: postgres
+    restart: always
+    shm_size: 1024mb
+    ports:
+      - 5432:5432
+    environment:
+      POSTGRES_PASSWORD: frieren
+
+  adminer:
+    image: adminer
+    restart: always
+    ports:
+      - 8080:8080
+
+  redis:
+    image: redis
+    restart: always
+    ports:
+      - 6379:6379
+```
+
+After, make a copy of the `.env.example` file and rename it to `.env`. The database variables should be pre-configured, but you'll need to fill in the rest.
+
+For the `AUTH_SECRET`, run the following in the command line:
+
+```bash
+$ pnpx auth secret
+```
+
+Now, let's get the Discord and GitHub authentication set up.
+
+For Discord, create an application in the developer portal, go to 'OAuth2', copy in the Client ID and Secret into the respective variables and also add this as a redirect URL: `http://localhost:3000/api/auth/callback/discord`.
+
+For GitHub, navigate to your profile settings, then 'Developer Settings', and create a new application. Set the homepage URL to `http://localhost:3000` and copy the Client ID and generate a new client secret. Finally, add in a callback URL with the value `http://localhost:3000/api/auth/callback/github`.
+
+After configuring the environment variables, you can run a development server.
+
+```bash
+$ pnpm dev
+```
+
+## Building
+
+It's a good idea to build the project locally before submitting a pull request. This helps catch any potential errors and see how things will look in a production environment.
+
+```bash
+# Build the project
+$ pnpm build
+
+# Run the built version
+$ pnpm start
+```
