 This is a SvelteKit-powered authentication service.
 
+## Requirements
+
+1. A MySQL or MariaDB database.
+2. Node.js 20+ or Docker.
+
 ## Set up
 
-1. Install dependenices - `npm install`.
-2. Configure the environment - `cp .env.example .env`.
-3. Generate secrets and stuff:
+1. Clone the repository.
+2. Install dependenices - `npm install`.
+3. Configure the environment - `cp .env.example .env`.
+4. Generate secrets and stuff:
    1. Session secret - `node -e 'console.log(require("crypto").randomBytes(16).toString("hex"))'`.
    2. Challenge secret - `node -e 'console.log(require("crypto").randomBytes(32).toString("hex"))'`.
    3. Generate JWT keys in the `private` directory - `openssl genpkey -out jwt.private.pem -algorithm RSA -pkeyopt rsa_keygen_bits:2048`.
    4. Also make the public key - `openssl rsa -in jwt.private.pem -pubout -outform PEM -out jwt.public.pem`.
-4. Build the application - `npm run build`.
-5. Run the application - `node -r dotenv/config build`.
+5. Build the application - `npm run build`.
+6. Run the application - `node -r dotenv/config build`.
