+The Localization Toolkit helps Flow Launcher C# plugin developers make the localization process easier.
+
+## Getting Started
+
+For C# plugins, install and reference [Flow.Launcher.Localization](www.nuget.org/packages/Flow.Launcher.Localization) via NuGet.
+
+## Build Properties
+
+These are properties you can configure in your `.csproj` file to customize the localization process. You can set them in the `<PropertyGroup>` section. For example, to set the `FLLUseDependencyInjection` property to `true`, add the following lines:
+
+```xml
+<PropertyGroup>
+    <FLLUseDependencyInjection>true</FLLUseDependencyInjection>
+</PropertyGroup>
+```
+
+### `FLLUseDependencyInjection`
+
+This flag specifies whether to use dependency injection to obtain an IPublicAPI instance. The default is `false`.
+- If set to `false`, the Main class (which must implement **[IPlugin](/API-Reference/Flow.Launcher.Plugin/IPlugin.md)** or **[IAsyncPlugin](/API-Reference/Flow.Launcher.Plugin/IAsyncPlugin.md)**)
+  must have a [PluginInitContext](/API-Reference/Flow.Launcher.Plugin/PluginInitContext.md) property that is at least `internal static`.
+- If set to `true`, you can access the `IPublicAPI` instance via `PublicApi.Instance` using dependency injection, and the Main class does not need to include a [PluginInitContext](/API-Reference/Flow.Launcher.Plugin/PluginInitContext.md) property.
+  (Note: This approach is not recommended for plugin projects at the moment since it limits compatibility to Flow Launcher 1.20.0 or later.)
+
+## Usage
+
+### Main Class
+
+The Main class must implement [IPluginI18n](/API-Reference/Flow.Launcher.Plugin/IPluginI18n.md).
+
+If `FLLUseDependencyInjection` is `false`, include a [PluginInitContext](/API-Reference/Flow.Launcher.Plugin/PluginInitContext.md) property, for example:
+
+```csharp
+ // Must implement IPluginI18n
+public class Main : IPlugin, IPluginI18n
+{
+    // Must be at least internal static
+    internal static PluginInitContext Context { get; private set; } = null!;
+}
+```
+
+### Localized Strings
+
+You can simplify your code by replacing calls like:
+```csharp
+Context.API.GetTranslation("flowlauncher_plugin_localization_demo_plugin_name")
+```
+with:
+```csharp
+Localize.flowlauncher_plugin_localization_demo_plugin_name()
+```
+
+If your localization string uses variables, it becomes even simpler! From this:
+```csharp
+string.Format(Context.API.GetTranslation("flowlauncher_plugin_localization_demo_value_with_keys"), firstName, lastName);
+```
+To this:
+```csharp
+Localize.flowlauncher_plugin_localization_demo_value_with_keys(firstName, lastName);
+```
+
+### Localized Enums
+
+For enum types (e.g., DemoEnum) that need localization in UI controls such as combo boxes, use the `EnumLocalize` attribute to enable localization. For each enum field:
+- Use `EnumLocalizeKey` to provide a custom localization key.
+- Use `EnumLocalizeValue` to provide a constant localization string.
+
+Example:
+
+```csharp
+[EnumLocalize] // Enable localization support
+public enum DemoEnum
+{
+    // Specific localization key
+    [EnumLocalizeKey("localize_key_1")]
+    Value1,
+
+    // Specific localization value
+    [EnumLocalizeValue("This is my enum value localization")]
+    Value2,
+
+    // Key takes precedence if both are present
+    [EnumLocalizeKey("localize_key_3")]
+    [EnumLocalizeValue("Localization Value")]
+    Value3,
+
+    // Using the Localize class. This way, you can't misspell localization keys, and if you rename
+    // them in your .xaml file, you won't forget to rename them here as well because the build will fail.
+    [EnumLocalizeKey(nameof(Localize.flowlauncher_plugin_localization_demo_plugin_description))]
+    Value4,
+}
+```
+
+Then, use the generated DemoEnumData class within your view model to bind to a combo box:
+
+```csharp
+// ComboBox ItemSource
+public List<DemoEnumData> AllDemoEnums { get; } = DemoEnumData.GetValues();
+
+// ComboBox SelectedValue
+public DemoEnum SelectedDemoEnum { get; set; }
+```
+
+In your XAML, bind as follows:
+
+```xml
+<ComboBox
+    DisplayMemberPath="Display"
+    ItemsSource="{Binding AllDemoEnums}"
+    SelectedValue="{Binding SelectedDemoEnum}"
+    SelectedValuePath="Value" />
+```
+
+To update localization strings when the language changes, you can call:
+
+```csharp
+DemoEnumData.UpdateLabels(AllDemoEnums);
+```
