 ## The Build Process
 
@@ -44,11 +45,4 @@ The build process is as follows:
   - If the `-upx` flag was provided, `upx` is invoked to compress the binary. Custom flags may be provided using the `-upxflags` flag.
   - If the `package` flag is given for a non Windows target, the application is bundled for the platform. On Mac, this creates a `.app` with the processed icons, the `Info.plist` in `build/darwin` and the compiled binary.

+# Next Steps
+
+Congratulations on generating your template!
+
+## Completing your template
+
+The next steps to complete the template are:
+
+  1. Complete the fields in the `template.json` file. 
+  2. Update `README.md`.
+  3. Edit `wails.tmpl.json` and ensure all fields are correct, especially:
+     - `html` - path to your `index.html`
+     - `frontend:install` - The command to install your frontend dependencies
+     - `frontend:build` - The command to build your frontend
+  4. Remove any `public` or `dist` directories.
+  5. Delete this file.
+
+## Testing your template
+
+You can test your template by running this command:
+
+`wails init -name test -t {{.TemplateDir}}`
+
+### Checklist 
+Once generated, do the following tests:
+  - Change into the new project directory and run `wails build`. A working binary should be generated in the `build/bin` project directory.
+  - Run `wails dev`. This will compile your backend and run it. You should be able to go into the frontend directory and run `npm run dev` (or whatever your dev command is) and this should run correctly. You should be able to then open a browser to your local dev server and the application should work.
+
+## Publishing your template
+
+You can publish a template to a git repository and use it as follows:
+
+`wails init -name test -t https://your/git/url`
+
+EG: 
+
+`wails init -name test -t https://github.com/leaanthony/testtemplate`

+## About
+
+About your template
+
+## Building 
+
+To build this project in debug mode, use `wails build`. For production, use `wails build -production`.
+To generate a platform native package, add the `-package` flag.
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. In another terminal, go into the `frontend` 
+directory and run `npm run dev`. The frontend dev server will run on http://localhost:5000. Connect to this
+in your browser and connect to your application.

+
+## About
+
+This is a basic Svelte template, using rollup to bundle the assets into a single JS file.
+Rollup is configured to do the following:
+
+  - Convert imported images to base64 strings
+  - Convert `url()` in `@font-face` declarations to base64 strings
+  - Bundle all css into the JS bundle
+  - Copy `index.html` from `frontend/src/` to `frontend/dist/`
+
+Clicking the button will call the backend 
+
+## Building 
+
+To build this project in debug mode, use `wails build`. For production, use `wails build -production`.
+To generate a platform native package, add the `-package` flag.
+
+## Live Development
+
+To run in live development mode, run `wails dev` in the project directory. In another terminal, go into the `frontend` 
+directory and run `npm run dev`. The frontend dev server will run on http://localhost:5000. Connect to this
+in your browser and connect to your application.

+*Looking for a shareable component template? Go here --> [sveltejs/component-template](https://github.com/sveltejs/component-template)*
+
+---
+
+# svelte app
+
+This is a project template for [Svelte](https://svelte.dev) apps. It lives at https://github.com/sveltejs/template.
+
+To create a new project based on this template using [degit](https://github.com/Rich-Harris/degit):
+
+```bash
+npx degit sveltejs/template svelte-app
+cd svelte-app
+```
+
+*Note that you will need to have [Node.js](https://nodejs.org) installed.*
+
+
+## Get started
+
+Install the dependencies...
+
+```bash
+cd svelte-app
+npm install
+```
+
+...then start [Rollup](https://rollupjs.org):
+
+```bash
+npm run dev
+```
+
+Navigate to [localhost:5000](http://localhost:5000). You should see your app running. Edit a component file in `src`, save it, and reload the page to see your changes.
+
+By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the `sirv` commands in package.json to include the option `--host 0.0.0.0`.
+
+If you're using [Visual Studio Code](https://code.visualstudio.com/) we recommend installing the official extension [Svelte for VS Code](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode). If you are using other editors you may need to install a plugin in order to get syntax highlighting and intellisense.
+
+## Building and running in production mode
+
+To create an optimised version of the app:
+
+```bash
+npm run build
+```
+
+You can run the newly built app with `npm run start`. This uses [sirv](https://github.com/lukeed/sirv), which is included in your package.json's `dependencies` so that the app will work when you deploy to platforms like [Heroku](https://heroku.com).
+
+
+## Single-page app mode
+
+By default, sirv will only respond to requests that match files in `public`. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.
+
+If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for *any* path. You can make it so by editing the `"start"` command in package.json:
+
+```js
+"start": "sirv public --single"
+```
+
+## Using TypeScript
+
+This template comes with a script to set up a TypeScript development environment, you can run it immediately after cloning the template with:
+
+```bash
+node scripts/setupTypeScript.js
+```
+
+Or remove the script via:
+
+```bash
+rm scripts/setupTypeScript.js
+```
+
+## Deploying to the web
+
+### With [Vercel](https://vercel.com)
+
+Install `vercel` if you haven't already:
+
+```bash
+npm install -g vercel
+```
+
+Then, from within your project folder:
+
+```bash
+cd public
+vercel deploy --name my-project
+```
+
+### With [surge](https://surge.sh/)
+
+Install `surge` if you haven't already:
+
+```bash
+npm install -g surge
+```
+
+Then, from within your project folder:
+
+```bash
+npm run build
+surge public my-project.surge.sh
+```

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The

+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
