 ### What did we do?
 
-Phoenix's default configuration of esbuild (via the Elixir wrapper) [does not allow you to use esbuild plugins](https://hexdocs.pm/phoenix/asset_management.html#esbuild-plugins). The standard Elixir `esbuild` package works great for simple projects with Phoenix hooks, but to use LiveSvelte we need a more complex setup.
-
-To use plugins, Phoenix recommends replacing the default build system with a build script. So, in setup, we go from using the standard `esbuild` package to using `esbuild` directly as a `node_module`.
-
-As a result, you'll notice some related changes:
-
--   A bunch of files get created in `/assets`.
--   There are some code changes in `/lib`.
--   We no longer use the standard Elixir `esbuild` watcher, as we created a new watcher that does the same thing.
-
-The setup process commented out some lines of code, like configuration in `dev.exs`. It's safe to delete commented-out code if you desire.
+LiveSvelte uses [Vite](https://vite.dev/) as its build tool with `@sveltejs/vite-plugin-svelte` for Svelte compilation. The `mix live_svelte.setup` task sets up the necessary Vite configuration in your `assets/` directory.

-### Building Static Files
+### Development Workflow
 
-Make the changes in `/assets/js` and run:
+LiveSvelte ships TypeScript source directly — there are no pre-built distribution files. Consumers compile the library source through their own Vite pipeline via the `live_svelte` package alias.
+
+When working on the library source in `assets/js/live_svelte/`, changes are picked up automatically by the example project's Vite builds:
 
 ```bash
-mix assets.build
+# From example_project/ — rebuild after library source changes:
+mix assets.js && mix compile
 ```
 
-Or run the watcher:
-
+For live development with HMR:
 ```bash
-mix assets.build --watch
+# Terminal 1: Phoenix server
+cd example_project && mix phx.server
+# Terminal 2: Vite dev server (HMR for Svelte + library changes)
+cd example_project/assets && npx vite
 ```
 
 **Type checking:** The LiveSvelte client library is written in TypeScript with a type-safe public API (no `any` in exported types). Consumers get type hints via the package `types` entry. From the library repo, run `npm run typecheck` in `live_svelte/assets` to run `tsc --noEmit`.
