Localization

Localizations can be added to the game using the LocalizationManager Singleton class. Currently, you can only add localizations to the language being currently used by the user (This will be fixed soon in a new version).

Using in-game

To use a localization, you must use your localization keyword for your item display names/descriptions, prefixed by a $.
For example, if you added a localization like for "item_desc" such that it maps to "item description here", then you could use it in the following way:

ItemDrop item = Prefab.GetComponent<ItemDrop>();
item.m_itemData.m_shared.m_description = "$item_desc";

Valheim's UI system will automatically replace all words (without spaces or punctuation) following a $ with matches from the Localization if found.

Example

In your mod's Awake function, you can register translation using the RegisterTranslation function

private void Awake()
{
    LocalizationManager.Instance.RegisterTranslation("item_desc", "Item description here");
}

which can then be used as shown above.
