-This combines [BIP39](https://bips.xyz/39) and a modified [BIP32](https://bips.xyz/32) into a scheme that allows the generation of a private key from a list of seed words.
+[BIP39](https://bips.xyz/39) is used to generate mnemonic seed words and derive a binary seed from them.
 
-BIP32 is modified to use the key `Nostr seed` instead of `Bitcoin seed` in the HMAC function.
+[BIP32](https://bips.xyz/32) is used to derive the path `m/44'/1237'/0'/0'` (according to the Nostr entry on [SLIP44](https://github.com/satoshilabs/slips/blob/master/slip-0044.md)).
 
-This document specifies the creation of a single Nostr private key, but it can be expanded in the future if "HD Wallets" ever become a relevant use case.
+This is the default for a basic, normal, single-key client.
 
-Steps for generating the private key:
-
-1. Follow the steps on BIP39 for generating the `mnemonic` and then the `seed` (512 bytes);
-2. Calculate `result = hmac-sha512(key = 'Nostr seed', data = seed)`;
-3. Use the first 32 bytes of `result` as the private key.
+Other types of clients can still get fancy and use other derivation paths for their own other purposes.
