Installation & License Activation

Real requirements for System (Spigot 1.8.8, Java 21, optional MongoDB/Redis/PAPI), the 1:1 build install, and how to enable the economy that ships switched off.

System is not a public download. After checkout, the developer prepares a personal 1:1 build and delivers it to you directly in your Discord ticket, together with your license details — the same ticket is where payments are discussed (the platform documentation covers payment methods, including Paying with Crypto). Because each build is issued to one buyer, installation is deliberately short: place the jar, start the server, activate the license.

#Requirements

Requirement	Details
Java	Java 21 or newer at runtime — the build is compiled with a Java 21 target
Server platform	Spigot 1.8.8, or a fork that preserves the 1.8.8 API surface and NMS `v1_8_R3`
Database	None required to boot. MongoDB 4.0+ is optional, for economy persistence; Redis 5.0+ is optional, for the economy read-through cache — both drivers are bundled inside the jar
PlaceholderAPI	Optional — for placeholders in the scoreboard, join/leave messages and book pages
Permission/chat providers	Vault, GroupManager, PermissionsEx or Essentials — all optional soft dependencies; System also registers its own providers when they are absent

That table is worth reading twice: there is nothing you must install first. MongoDB, Redis, PlaceholderAPI and the permission providers are all declared as soft dependencies, and the heavy libraries (the MongoDB driver, the Jedis Redis client, the Vault API) are shaded into the build you receive. A bare 1.8.8 server plus the jar is a complete installation.

#Install your personal build

Complete the checkout and open a ticket on the official Discord server (https://discord.gg/kEPvGp8Yz7).
Receive your personal build and license key — delivered to you directly after payment is confirmed, usually within hours, with setup help included until everything runs.
Drop the delivered jar into the plugins/ folder of your Spigot 1.8.8 server.
Optionally install PlaceholderAPI or any other integration you plan to use — none of them are required to boot.
Start the server.
Complete the license activation for this server as instructed in your delivery message — System is licensed per server, with IP and hardware binding through the Nerotek loader.
Verify the plugin came up cleanly with /system status.
Configure at your own pace — see Configuration Workflow.

#Turning the economy on

One default surprises people, so it is stated here in plain terms: the economy subsystem ships disabled. This is deliberate — a lobby that does not want an economy should not run one. To enable it, set addons.economy.enabled: true in config.yml. The economy also requires Vault availability in one of the two forms described on the overview page: an external Vault plugin, or System's own built-in vault addon (addons.vault.enabled: true).

Until both switches are on, the economy commands exist but respond with a quiet no-op instead of erroring — disabled addons swap in a silent handler, so your command tables never lie. Once enabled, /balance, /pay and /money give-take-set come alive, and balances persist to MongoDB with the Redis read-through cache in front of it when you have connected those services.

Warning:The license is bound to the server it was issued for — IP and hardware limits are part of the protection. If you migrate to new hardware or your server IPs change, do not fight the binding: request a license reset through your DM conversation (see the platform page Requesting a License Reset).

#Which optional integration, when

MongoDB 4.0+ — add it when your economy must persist reliably across restarts and servers.
Redis 5.0+ — add it when you want the economy read-through cache and sorted-set leaderboard in front of MongoDB.
PlaceholderAPI — add it when you want placeholders in the scoreboard and messages; the scoreboard staggers resolution across bucket tiers either way.
Vault, GroupManager, PermissionsEx or Essentials — add them for richer permission and chat providers; System's own providers keep everything working without them.

Tip:/system reload applies configuration changes without a restart, and /system status gives you a live overview — the two commands you will use most while setting up.
