-### Node types
-* Input Node: A node that starts a new flow. Upon meeting a pre-configured condition, it creates a new msg object that travels around the flow.
-
-* Query Node: A node that does something when it receives an incoming msg object
-
-* Watch Node: An input or query node that specifically watches local or remote files/directories for any change
-
-* Output Node: A node where a flow terminates. It usually produces some output accessible outside the Node-RED runtime
-
-### Technical terms
-
-* Canvas: The drawing area in the UI on which flows are designed
-
-* Context: JavaScript object used by function nodes to store state between function node invocations.
-
-* Credentials: Special properties of nodes that don't get exported/imported as flows. They're stored in a separate flows file. Example credentials are: tokens provided by users or data obtained by nodes (such as security keys)
-
-* File Event: Events that happen to files/directories such as access/change/deletion.
-
-* Flow: Nodes wired together to achieve a desired functionality
-
-* Global Context: A JavaScript object that is shared and is accessible by all function nodes. It is used to store global state.
-
-* Glob Pattern: Pattern matching, based on wildcard characters. Glob is the particular pattern. Globs are simpler than regular expressions. The term is widely used in Unix-like environments.
-
-* Initialization: After hitting the deploy button in the UI, nodes that are on the canvas might run necessary start-up logic, called initialization.
-
-* msg: The object that is the input into nodes and is what nodes output. It's the data being passed around in flows
-
-* msg.payload: The meaningful, processed data representation/outcome of a node operation such as an image buffer
-
-* OAuth: Is an open standard to authorization. It provides client applications delegated, secure access to server resources on behalf of the resource owner. (Source: [Wikipedia](http://en.wikipedia.org/wiki/OAuth))
-
-* Wire: The connection between nodes. Nodes might have more than one wire leaving them and nodes might have multiple outputs.
