+### Does it work?
 
 YES!  This script has already been used to recover a wallet containing 1 bitcoin, so it has already paid its dues  :-)
 
+### Can I use this if I don't know any of the addresses?
+
+No, unfortunately you must know 1 or more addresses generated by the wallet, otherwise the tool would be too slow to use.  If you know the first address (index zero `0` of the first account `0`) this will be fastest search.
+
+### Does it support bech32 native SegWit wallets?
+
+No, unfortunately these wallets (path: `m/84'/0'/0'`) are not supported.  It would be _possible_ to add support by grabbing code from Electrum though. Pull Requests welcome.
+
+### Can this help me recover a wallet where I don't know the seed phrase?
+
+No, unfortunately this software does not support that functionality.  If you know part of the seed phrase (especially the last part) you _might_ be able to brute force it as the last word is a checksum indicating you have all the other words correct.

-* Allow passing parameters for wallet on commandline
+* Allow passing parameters for wallet on commandline.
 * Optimize!  Code (copied from Electrum tests) is very slow for this purpose.
