+Custom dictionaries
+-------------------
+Both the *zxcvbn-c* and the *zxcvbn-cpp* engines allow to use a
+custom dictionary of passwords (in addition to the one already
+built in those libraries).
+
+A custom dictionary may be embedded in the program at build
+time with the *configure* option `--with-dict=foo`, where *foo*
+is the path to the dictionary to embed. The file should be a
+simple text file containing one word per line.
+
+In addition, a custom dictionary may also be read from file at
+run-time, using the `-d foo` or `--dict foo` option. Again, the
+*foo* file is expected to be a text file containing one word
+per line.
