+# Availability Subsystems
+
+The availability subsystems are responsible for ensuring that Proofs of Validity of backed candidates are widely
+available within the validator set, without requiring every node to retain a full copy. They accomplish this by broadly
+distributing erasure-coded chunks of the PoV, keeping track of which validator has which chunk by means of signed
+bitfields. They are also responsible for reassembling a complete PoV when required, e.g. when an approval checker needs
+to validate a teyrchain block.
