git clone --recurse-submodules https://github.com/longbridge/developers.git
cd developers
bun install
bun run dev

If you already cloned without --recurse-submodules:

git submodule update --init --recursive
bun run dev

The dev server starts at http://localhost:5173 and connects to the canary API. Use bun run dev:prod to connect to the production API instead.
