# Overview

Core is an opinionated framework for building Go desktop apps with Wails, providing a small set of focused modules you can mix into your app. It ships with sensible defaults and a demo app that doubles as in‑app help.

## Quick start
```go
package main

import (
    "github.com/wailsapp/wails/v3/pkg/application"
    core "github.com/Snider/Core"
)

func main() {
    app := core.New(
        core.WithServiceLock(),
    )
    wailsApp := application.NewWithOptions(&application.Options{
        Bind: []interface{}{app},
    })
    wailsApp.Run()
}
```

## Services
```go
package demo

import (
    core "github.com/Snider/Core"
)

// Register your service
func Register(c *core.Core) error {
    return c.RegisterService("demo", &Demo{core: c})
}
```

## Display example
```go
package display

import (
    "context"
    "github.com/wailsapp/wails/v3/pkg/application"
)

// Open a window on startup
func (d *API) ServiceStartup(ctx context.Context, _ application.ServiceOptions) error {
    d.OpenWindow(
        OptName("main"),
        OptHeight(900),
        OptWidth(1280),
        OptURL("/"),
        OptTitle("Core"),
