 ## The Passwordlist ##
 
-If you already have a simple list of whole passwords you'd like to test, and you don't need any of the features described above, you can use the `--passwordlist` command-line option (instead of the `--tokenlist` option as described later in the [Running *btcrecover*](#running-btcrecover) section). If your password contains any non-[ASCII](https://en.wikipedia.org/wiki/ASCII) (non-English) characters, you should read the section on [Unicode Support](#unicode-support) before continuing.

The passwordlist is just a standard text file, with one password per line. (It can be either raw text or also compressed with gzip)If your password contains any non-[ASCII](https://en.wikipedia.org/wiki/ASCII) (non-English) characters, you should read the section on [Unicode Support](#unicode-support) before continuing.
 
 If you specify `--passwordlist` without a file, *btcrecover* will prompt you to type in a list of passwords, one per line, in the Command Prompt window. If you already have a text file with the passwords in it, you can use `--passwordlist FILE` instead (replacing `FILE` with the file name).
