+# Transaction Payment Pallet
+
+This pallet provides the basic logic needed to pay the absolute minimum amount needed for a
+transaction to be included. This includes:
+  - _weight fee_: A fee proportional to amount of weight a transaction consumes.
+  - _length fee_: A fee proportional to the encoded length of the transaction.
+  - _tip_: An optional tip. Tip increases the priority of the transaction, giving it a higher
+    chance to be included by the transaction queue.
+
+Additionally, this pallet allows one to configure:
+  - The mapping between one unit of weight to one unit of fee via [`Config::WeightToFee`].
+  - A means of updating the fee for the next block, via defining a multiplier, based on the
+    final state of the chain at the end of the previous block. This can be configured via
+    [`Config::FeeMultiplierUpdate`]
