+# 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`]

+
+## Asset Transaction Payment Pallet
+
+This pallet allows runtimes that include it to pay for transactions in assets other than the
+native token of the chain.
+
+### Overview
+It does this by extending transactions to include an optional `AssetId` that specifies the asset
+to be used for payment (defaulting to the native token on `None`). It expects an
+[`OnChargeAssetTransaction`] implementation analogously to [`pallet-transaction-payment-mangata`]. The
+included [`FungiblesAdapter`] (implementing [`OnChargeAssetTransaction`]) determines the fee
+amount by converting the fee calculated by [`pallet-transaction-payment-mangata`] into the desired
+asset.
+
+### Integration
+This pallet wraps FRAME's transaction payment pallet and functions as a replacement. This means
+you should include both pallets in your `construct_runtime` macro, but only include this
+pallet's [`SignedExtension`] ([`ChargeAssetTxPayment`]).
