 ## Quick Review of BIP-39 Mnemonic Seed Phrases
 The typical method for backing up a Bitcoin wallet is to store its [BIP-39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki) mnemonic seed phrase consisting of 12 or 24 words.
 
-**SeedQR specifically assumes and recommends using the English BIP39 wordlist.** While BIP39 supports multiple language-specific wordlists (e.g., Japanese, Spanish, French), there is no mechanism to specify or detect which language wordlist was used when creating or scanning a SeedQR. Using a non-English wordlist may result in incorrect or invalid seeds.

-Each word comes from a [list of 2048 words](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). The words themselves are meaningless; all that matters is the word's position number (aka index) in the word list.
+Each word comes from a [list of 2048 words](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). The words are sorted alphabetically. This allows us to refer to a specific word by its position number (aka index) in the word list.
 
 For example, "tomato" is the 1,825th word in the list.
 
-But code always starts counting list items with zero. So the index of "tomato" is actually `1824` (if you're looking at the GitHub wordlist line numbers, just remember to always subtract one).
+But code always starts counting list items from zero. So the index of "tomato" is actually `1824`. The GitHub wordlist and most other resources number the words in a human-friendly manner that starts with `1`. But for SeedQR you'll have to remember to subtract one from any list that starts with `1` to get the correct index number.
