+# loft
+
+A minimal, self-hosted web app (with a cloud storage option planned), built as a learning exercise to get more familiar with Axum and Svelte.
+
+## Quick start
+```bash
+git clone https://git.stefiosif.dev/stefiosif/loft
+cd loft
+cp .env.example .env
+
+# Run in Docker (http://localhost:3000):
+docker compose up -d
+
+# Run locally (http://localhost:5173):
+cp backend/.env.example backend/.env
+just db-setup
+# inside tmux together frontend and backend
+just watch
+# or separately
+just watch-backend
+just watch-frontend
+
+# API docs (Swagger UI, generated with utoipa): http://localhost:3000/swagger-ui
+
+# Run tests:
+cp backend/.env.test.example backend/.env.test
+just watch-test
+```
+
+## Commands
+Run `just --list` to see all recipes.
