 ### Compilation
 
-To make the core library code work across all browsers, we need to compile the raw TypeScript and React code to plain JavaScript. We can accomplish this with `tsup`, which uses `esbuild` to greatly improve performance.

 Running `pnpm build` from the root of the Turborepo will run the `build` command defined in each package's `package.json` file. Turborepo runs each `build` in parallel and caches & hashes the output to speed up future builds.
