Org-evil provides integration between Evil and Org through various means such as contextual keybindings. Org-evil has a standard set of keybindings, with additional bindings that vary depending on the location and type of Org file being edited, for example some bindings are only active within a table. All the bindings aim to be fairly intuitive for Evil users, so there shouldn't be any huge surprises. For more information see the README.
