+# Installation issues
+
+Here's some common issues you might encounter when trying to install Modular Avatar.
+
+## "Failed to add Repo"
+
+![Failed to add Repo error](failed-to-add-repo.png)
+
+Due to a bug in the VCC, you might sometimes get this error when trying to add the Modular Avatar repository.
+Usually this means the repository has already been added. If you can't see the Modular Avatar package in the package
+list, the repository might be disabled. Click "Cancel", then look in the "Community Repositories" list for the "bd_"
+repository. Make sure the checkbox is checked.

+
+VCCのバグの影響で、Modular Avatarリポジトリを追加しようとすると、このようなエラーが発生することがあります。
+リポジトリが既に追加されていることを意味することが多いです。パッケージリストにModular Avatarパッケージが表示されない場合は、
+リポジトリが無効になっている可能性があります。いったん"Cancel"をクリックして、"Community Repositories"リストから"bd_"リポジトリを
+探してみてください。チェックボックスがオフになっている場合はチェックを入れてください。
