# AddLocalizedString(string,string)

Method in [Localization](https://docs.yarnspinner.dev/2.4/api/csharp/yarn.unity/yarn.unity.localization)

## Summary

Adds a new string to the runtime string table.

```csharp
public void AddLocalizedString(string key, string value)
```

## Remarks

This method updates the localisation's runtime string table, which is useful for adding or changing the localisation during gameplay or in a built player. It doesn't modify the asset on disk, and any changes made will be lost when gameplay ends.
