 A UI tool for downloading files from a Pod.
 The application is also the first Avalonia UI and C# UI app I have written.
 
+## Usage
+
+Just start the executable and select the cluster, namespace and pod you want to download files from.
+Then select the files you want to download and click the download button.
+
+The available clusters are read from the `~/.kube/config` file.
+
+## Limitations
+It only works on linux containers and the container must support `find` and `tar`.
