Get\Set permissions for folder in library SharePoint 2013 using C# and CSOM

Hi.

I have a folder in the library SharePoint 2013. It creates a subfolder. How to get (set) permissions to created subfolder and the parent folder?

clientContext = new ClientContext(serverUrl);
rootWeb = clientContext.Web;
List list = lists.GetById("some_id"); //get list in library
clientContext.Load<List>(list);
clientContext.ExecuteQuery();

Folder rootFolder = list.RootFolder.Folders.GetByUrl("ParentFolder");
Folder newFolder = list.RootFolder.Folders.Add("TestDocsConteiner");
newFolder.Folders.Add("SubFolder");
clientContext.ExecuteQuery();

newFolder => Set permissions for unique user

Thanks!
