   Settings → Plugins → ⚙️ → Install Plugin from Disk Select: intellij-lumos-X.X.X.zip Restart IDE 

1. Open or create a .lumos file:

#[solana] #[account] struct Player { wallet: PublicKey, score: u64, level: u16, }

   • ✅ Syntax highlighting
   • ✅ Auto-completion (Pub → PublicKey)

2. System PATH

Custom path (if needed):

Settings → Languages & Frameworks → Language Servers → Configure server manually: /path/to/lumos-lsp
