+
+## About
+
+This is the official Wails Svelte-TS template.
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. This will run a Vite development
+server that will provide very fast hot reload of your frontend changes. If you want to develop in a browser
+and have access to your Go methods, there is also a dev server that runs on http://localhost:34115. Connect
+to this in your browser, and you can call your Go code from devtools.
+
+## Building
+
+To build a redistributable, production mode package, use `wails build`.

+# Build Directory
+
+The build directory is used to house all the build files and assets for your application. 
+
+The structure is:
+
+* bin - Output directory
+* darwin - macOS specific files
+* windows - Windows specific files
+
+## Mac
+
+The `darwin` directory holds files specific to Mac builds.
+These may be customised and used as part of the build. To return these files to the default state, simply delete them
+and
+build with `wails build`.
+
+The directory contains the following files:
+
+- `Info.plist` - the main plist file used for Mac builds. It is used when building using `wails build`.
+- `Info.dev.plist` - same as the main plist file but used when building using `wails dev`.
+
+## Windows
+
+The `windows` directory contains the manifest and rc files used when building with `wails build`.
+These may be customised for your application. To return these files to the default state, simply delete them and
+build with `wails build`.
+
+- `icon.ico` - The icon used for the application. This is used when building using `wails build`. If you wish to
+  use a different icon, simply replace this file with your own. If it is missing, a new `icon.ico` file
+  will be created using the `appicon.png` file in the build directory.
+- `installer/*` - The files used to create the Windows installer. These are used when building using `wails build`.
+- `info.json` - Application details used for Windows builds. The data here will be used by the Windows installer,
+  as well as the application itself (right click the exe -> properties -> details)
+- `wails.exe.manifest` - The main application manifest file.

+# Svelte + TS + Vite
+
+This template should help get you started developing with Svelte and TypeScript in Vite.
+
+## Recommended IDE Setup
+
+[VS Code](https://code.visualstudio.com/)
+
++ [Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode).
+
+## Need an official Svelte framework?
+
+Check out [SvelteKit](https://github.com/sveltejs/kit#readme), which is also powered by Vite. Deploy anywhere with its
+serverless-first approach and adapt to various platforms, with out of the box support for TypeScript, SCSS, and Less,
+and easily-added support for mdsvex, GraphQL, PostCSS, Tailwind CSS, and more.
+
+## Technical considerations
+
+**Why use this over SvelteKit?**
+
+- It brings its own routing solution which might not be preferable for some users.
+- It is first and foremost a framework that just happens to use Vite under the hood, not a Vite app.
+  `vite dev` and `vite build` wouldn't work in a SvelteKit environment, for example.
+
+This template contains as little as possible to get started with Vite + TypeScript + Svelte, while taking into account
+the developer experience with regards to HMR and intellisense. It demonstrates capabilities on par with the
+other `create-vite` templates and is a good starting point for beginners dipping their toes into a Vite + Svelte
+project.
+
+Should you later need the extended capabilities and extensibility provided by SvelteKit, the template has been
+structured similarly to SvelteKit so that it is easy to migrate.
+
+**Why `global.d.ts` instead of `compilerOptions.types` inside `jsconfig.json` or `tsconfig.json`?**
+
+Setting `compilerOptions.types` shuts out all other types not explicitly listed in the configuration. Using triple-slash
+references keeps the default TypeScript setting of accepting type information from the entire workspace, while also
+adding `svelte` and `vite/client` type information.
+
+**Why include `.vscode/extensions.json`?**
+
+Other templates indirectly recommend extensions via the README, but this file allows VS Code to prompt the user to
+install the recommended extension upon opening the project.
+
+**Why enable `allowJs` in the TS template?**
+
+While `allowJs: false` would indeed prevent the use of `.js` files in the project, it does not prevent the use of
+JavaScript syntax in `.svelte` files. In addition, it would force `checkJs: false`, bringing the worst of both worlds:
+not being able to guarantee the entire codebase is TypeScript, and also having worse typechecking for the existing
+JavaScript. In addition, there are valid use cases in which a mixed codebase may be relevant.
+
+**Why is HMR not preserving my local component state?**
+
+HMR state preservation comes with a number of gotchas! It has been disabled by default in both `svelte-hmr`
+and `@sveltejs/vite-plugin-svelte` due to its often surprising behavior. You can read the
+details [here](https://github.com/rixo/svelte-hmr#svelte-hmr).
+
+If you have state that's important to retain within a component, consider creating an external store which would not be
+replaced by HMR.
+
+```ts
+// store.ts
+// An extremely simple external store
+import { writable } from 'svelte/store'
+export default writable(0)
+```
