+Wallet
+------
+
+`ord` wallets rely on Bitcoin Core for private key management and transaction
+signing, so `ord` wallet commands interact with Bitcoin Core wallets. `ord`
+should not be used in the presence of  wallets that contain a material amount
+of funds. Using `bitcoin-cli` commands and RPC calls with `ord` wallets may
+lead to loss of sats and inscriptions.
+
+### Pre-alpha wallet migration
+
+Alpha `ord` wallets are not compatible with wallets created by previous
+versions of `ord`. To migrate, use `ord wallet send` from the old wallet to
+send sats and inscriptions to addresses generated by the new wallet with `ord
+wallet receive`.
