-## Plugins
-
-Plugins are a way to extend the functionality of your Wails application.
-
-### Creating a plugin
-
-Plugins are standard Go structure that adhere to the following interface:
-
-```go
-type Plugin interface {
-    Name() string
-    Init(*application.App) error
-    Shutdown() 
-    CallableByJS() []string
-    InjectJS() string
-}
-```
-
-The `Name()` method returns the name of the plugin. This is used for logging purposes.
-
-The `Init(*application.App) error` method is called when the plugin is loaded. The `*application.App`
-parameter is the application that the plugin is being loaded into. Any errors will prevent
-the application from starting.
-
-The `Shutdown()` method is called when the application is shutting down.
-
-The `CallableByJS()` method returns a list of exported functions that can be called from
-the frontend. These method names must exactly match the names of the methods exported
-by the plugin.
-
-The `InjectJS()` method returns JavaScript that should be injected into all windows as they are created. This is useful for adding custom JavaScript functions that complement the plugin.
-
-### Tips
-
-#### Enums
-
-In Go, enums are often defined as a type and a set of constants. For example:
-
-```go
-type MyEnum int
-
-const (
-    MyEnumOne MyEnum = iota
-    MyEnumTwo
-    MyEnumThree
-)
-```
-
-Due to incompatibility between Go and JavaScript, custom types cannot be used in this way. The best strategy is to use a type alias for float64:
-
-```go
-type MyEnum = float64
-
-const (
-    MyEnumOne MyEnum = iota
-    MyEnumTwo
-    MyEnumThree
-)
-```
-
-In Javascript, you can then use the following:
-
-```js
-const MyEnum = {
-    MyEnumOne: 0,
-    MyEnumTwo: 1,
-    MyEnumThree: 2
-}
-```
-
-- Why use `float64`? Can't we use `int`? 
-  - Because JavaScript doesn't have a concept of `int`. Everything is a `number`, which translates to `float64` in Go. There are also restrictions on casting types in Go's reflection package, which means using `int` doesn't work.
