-## Modes and Actions
-
-The basic paradigm in Scotty3D is that there are six different _modes_, each
-of which lets you perform certain class of actions. For instance, in `Model` mode, you
-can perform actions associated with modeling, such as moving mesh elements and performing global mesh operations.
-When in `Animate` mode, you can perform actions associated with animation. Etc.
-Within a given mode, you can
-switch between actions by hitting the appropriate key; keyboard commands are
-listed below for each mode. Note that the input scheme may change depending on
-the mode. For instance, key commands in `Model` mode may result in
-different actions in `Render` mode.
-
-For the detailed documentation, see the guides of each mode: 
-- [Layout Mode](/docs/guide/layout.md)
-- [Model Mode](/docs/guide/model.md)
-- [Render Mode](/docs/guide/render.md)
-- [Rigging Mode](/docs/guide/rig.md)
-- [Animate Mode](/docs/guide/animate.md)
-- [Simulate Mode](/docs/guide/simulate.md)
-
-The current mode is displayed as the "pressed" button in the menu bar, and available actions
-are are detailed in the left sidebar. Note that some actions are only available when a model/element/etc. is selected.

-
-## Global Navigation
-
-In all modes, you can move the camera around and select scene elements. Information about your selection will be shown in the left sidebar.
-
-The camera can be manipulated in three ways:
-- Rotate: holding shift, left-clicking, and dragging will orbit the camera about the scene. Holding middle click and dragging has the same effect.
-- Zoom: using the scroll wheel or scrolling on your trackpad will move the camera towards or away from its center.
-- Translate: right-clicking (or using multi-touch on a trackpad, e.g., two-finger click-and-drag) and dragging will move the camera around the scene.
-
-## Global Preferences
-
-You can open the preferences window from the edit option in the menu bar.
-- Multisampling: this controls how many samples are used for MSAA when rendering scene objects in the Scotty3D interface. If your computer struggles to render complex scenes, try changing this to `1`.
-
-## Global Undo
-
-As is typical, all operations on scene objects, meshes, etc. are un and re-doable using Control/Command-Z to undo and Control/Command-Y to redo. These actions are also available from the `Edit` option in the menu bar.
