---

Step 1 — Download Blueprint

Download the latest Blueprint.jar from the releases page.

---

Step 2 — Install the Plugin

Place Blueprint.jar in your server's plugins/ folder:

your-server/
└── plugins/
    └── Blueprint.jar

---

Step 3 — Start the Server

Start (or restart) your Paper server. Blueprint will generate its configuration and data files on first run:

plugins/Blueprint/
├── config.yml       # Plugin configuration
└── blueprint.db     # SQLite database (auto-created)

---

Step 4 — Configure

Open plugins/Blueprint/config.yml and adjust settings to suit your server. See the Configuration page for a full reference.

Reload the plugin after making config changes:

/blueprint reload
