+# Build
+
+The build command processes the Wails project and generates an application binary. 
+
+## Usage
+
+`wails build <flags>`
+
+### Flags
+
+| Flag           | Details      | Default |
+| :------------- | :----------- | :------ |
+| -clean | Clean the bin directory before building   | |
+| -compiler path/to/compiler  | Use a different go compiler, eg go1.15beta1 | go |
+| -ldflags "custom ld flags" | Use given ldflags | | 
+| -o path/to/binary | Compile to given path/filename | |
+| -k | Keep generated assets | |
+| -package | Create a platform specific package | |
+| -production | Compile in production mode: -ldflags="-w -s" + "-h windows" on Windows | |
+| -tags | Build tags to pass to Go compiler (quoted and space separated) | |
+| -upx | Compress final binary with UPX (if installed) | |
+| -upxflags "custom flags" | Flags to pass to upx | |
+| -v int | Verbosity level (0 - silent, 1 - default, 2 - verbose) | 1 |
+| -delve | If true, runs delve on the compiled binary | false |
+
+## The Build Process
+
+The build process is as follows:
+
+  - The flags are processed, and an Options struct built containing the build context.
+  - The type of target is determined, and a custom build process is followed for target.
+
+### Desktop Target 
+
+  - The frontend dependencies are installed. The command is read from the project file `wails.json` under the key `frontend:install` and executed in the `frontend` directory. If this is not defined, it is ignored.
+  - The frontend is then built. This command is read from the project file `wails.json` under the key `frontend:install` and executed in the `frontend` directory. If this is not defined, it is ignored.
+  - The project directory is checked to see if the `build` directory exists. If not, it is created and default project assets are copied to it.
+  - An asset bundle is then created by reading the `html` key from `wails.json` and loading the referenced file. This is then parsed, looking for local Javascript and CSS references. Those files are in turn loaded into memory, converted to C data and saved into the asset bundle located at `build/assets.h`, which also includes the original HTML.
+  - The application icon is then processed: if there is no `build/appicon.png`, a default icon is copied. On Windows, an `app.ico` file is generated from this png. On Mac, `icons.icns` is generated.
+  - If there are icons in the `build/tray` directory, these are processed, converted to C data and saved as `build/trayicons.h`, ready for the compilation step.
+  - If there are icons in the `build/dialog` directory, these are processed, converted to C data and saved as `build/userdialogicons.h`, ready for the compilation step.
+  - If the `-package` flag is given for a Windows target, the Windows assets in the `build/windows` directory are processed: manifest + icons compiled to a `.syso` file (deleted after compilation).
+  - If we are building a universal binary for Mac, the application is compiled for both `arm64` and `amd64`. The `lipo` tool is then executed to create the universal binary.
+  - If we are not building a universal binary for Mac, the application is built using `go build`, using build tags to indicate type of application and build mode (debug/production).
+  - 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.

+## How it works
+
+The project is built using a special mode that starts a webserver and starts listening to port 34115. When the frontend project is run independently, so long as the JS is wrapped with the runtime method `ready`, then the frontend will connect to the backend code via websockets. The interface should be present in your browser, and you should be able to interact with the backend as you would in a desktop app.

+# 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
+```
