 ## Your first run
 
+The repo ships two sample apps. `examples/folio` is a Kotlin Multiplatform personal-ledger app that covers Android, iOS, and web (wasmJs) from one shared codebase. `examples/folio-web` is a smaller React + Vite app that covers only the web path. Both carry a TypeScript spec under `sanderling/spec.ts`. Install `just`, then pick a target below.
