⚠️You can set up / update database only if you have purchased related to backend addon(-s) (auth, account management, etc.)

Create a project on Supabase or another service with remote PostgreSQL
Open "Project Settings" -> "(Configuration) Database" -> Copy connection string
Rename .env.example to .env (you should do that on quickstart steps before)
Open .env and set DATABASE_URL= & DIRECT_DATABASE_URL= to your connection string
4.5. FOR VERCEL AND OTHER SERVERLESS DEPLOYMENTS .env :
• for DATABASE_URL use connection string w/ port 6543 (Transaction pooler) and add ?pgbouncer=true
• for DIRECT_DATABASE_URL use connection string w/ port 5432 (Session pooler)
4.6 FOR LOCAL .env FILE:
• for local develompent use connection strings w/ port 5432 (put same string in both env variables)
Generate 64 characters length string http://www.unit-conversion.info/texttools/random-string-generator/ and set TOKEN_SECRET= to this value
Set database provider to postgresql (in schema.prisma and .env -> DB_PROVIDER)
Copy / merge models from downloaded files into schema folder
Run npm install , then npm run prisma, npm run prisma:update and then npm run dev
Open http://localhost:3000/
To update database, merge models from your local schema.prisma with models from addon(-s) you've purchased or your own code and run npm run prisma:update.

Create an admin user, open http://localhost:3000/sign-up and register a new user
After done, log out and run in terminal: npm run db, then in Users table change your new user`s role to ADMIN and press save.
Run npm run dev and login back to account, you wil see an admin dashboard with admin blog section, where you can
Create blog posts and other things (paid separate features) 😉

⚠️ While switching between PostgreSQL / Local PostgreSQL / SQLite, delete or rename "migrations" folder, e.g. if switching from SQLite, rename to "sqlite-migrations", while switching back rename PostgreSQL "migrations" to "postgres-migrations", and "sqlite-migrations" back to "migrations". Same for schema files. After these manipulations don't forget to run "npm run prisma" and "npm run prisma:update"
