+## Keyfork Top-Level Binary
+
+The `keyfork` binary is the most user-friendly interface for interacting with
+the Keyfork toolchain. It offers commands that should not take any scriptable
+input and should not produce any script-readable output. Such operations that
+require script compatibility should be made into their own utilities, with the
+higher level interface of interacting with them left solely to `keyfork`.
+
+For instance, the program to generate system entropy is `keyfork-entropy`. It
+accepts an arbitrary length and spits out a hex-encoded chunk of data. The
+program to convert that entropy into a seed is `keyfork-mnemonic-from-seed`. It
+takes entropy from input and converts it into a seed. The combination of the
+two, generating entropy and converting it to a mnemonic, is managed through
+Keyfork: `keyfork mnemonic generate`, which can also be used to offer more
+options down the line, such as generating a mnemonic from tarot or playing
+cards, or dice.
