-# Taproot
-
-A simple keyspend example that is possible with the current API is below.
-
-## Current state of taproot support
-
-- [x] segwit v1 address support via bech32m
-- [x] segwit v1 sighash calculation on Transaction class
-
-## TODO
-
-- [ ] p2tr payment API to make script spends easier
-- [ ] Support within the Psbt class
-
-## Example
-
-### Requirements
-- npm dependencies
-  - bitcoinjs-lib v6.x.x
-  - bip32 v3.x.x
-  - tiny-secp256k1 v2.x.x
-  - regtest-client vx.x.x
-- local regtest-server docker container running
-  - `docker run -d -p 8080:8080 junderw/bitcoinjs-regtest-server`
