+# 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 |
+
+## 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.
+
+### Server Target
+
+TBD
+
+### Hybrid Target

+# Dev
+
+The dev command allows you to develop your application through a standard browser. 
+
+## Usage
+
+`wails dev <flags>`
+
+### Flags
+
+| Flag           | Details      | Default |
+| :------------- | :----------- | :------ |
+| -compiler path/to/compiler  | Use a different go compiler, eg go1.15beta1 | go |
+| -ldflags "custom ld flags" | Use given ldflags | | 
+| -e list,of,extensions | File extensions to trigger rebuilds | go |
+| -w | Show warnings | false |
+| -v int | Verbosity level (0 - silent, 1 - default, 2 - verbose) | 1 |
+| -loglevel  | Loglevel to pass to the application - Trace, Debug, Info, Warning, Error | Debug |
+
+## 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. Delete this file.
+
+## Testing your template
+
+You can test your template by running this command:
+
+`wails init -name test -t /path/to/your/new/template`
+
+### 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 template uses vanilla JS / HTML and CSS. [Rollup](https://rollupjs.org/guide/en/) is used for processing and bundling the files.
+
+## 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.
