 some old words are rarely used and are common misspellings.  These do appear
 in a dictionary but not in a word list.
 
+There are two formats: one with affix compression and one without.  The files
+with affix compression are used by Myspell (Mozilla and OpenOffice.org).  This
+requires two files, one with .aff and one with .dic extension.  The second
+format is a list of words.
+
+
+FORMAT OF WORD LIST
+
+The words must appear one per line.  That is all that is required.  Optional
+items are:
+- Empty and blank lines are ignored.
+- Lines starting with a # are ignored (comment lines).
+- A line starting with "=encoding=" before any word.  After the second '='
+  comes an encoding name.  This tells Vim to setup conversion from the
+  specified encoding to 'encoding'.
+- Other lines starting with '=' are special.  The ones that are not recognized
+  are ignored (but you do get a warning message).
+
+
+FORMAT WITH AFFIX COMPRESSION
+
 There are two files: the basic word list and an affix file.  The affixes are
 used to modify the basic words to get the full word list.  This significantly
 reduces the number of words, especially for a language like Polish.  This is
