+Taking inspiration from prefix keys and prefix arguments, Transient
+implements a similar abstraction involving a prefix command, infix
+arguments and suffix commands. We could call this abstraction a
+"transient command", but because it always involves at least two
+commands (a prefix and a suffix) we prefer to call it just a
+"transient".
+
+When the user calls a transient prefix command, then a transient
+(temporary) keymap is activated, which binds the transient's infix
+and suffix commands, and functions that control the transient state
+are added to `pre-command-hook` and `post-command-hook`. The available
+suffix and infix commands and their state are shown in a popup buffer
+until the transient is exited by invoking a suffix command.
+
+Calling an infix command causes its value to be changed, possibly by
+reading a new value in the minibuffer.
+
+Calling a suffix command usually causes the transient to be exited but
+suffix commands can also be configured to not exit the transient.
