+    """
+    The .dict file is a pure data sequence, as the offset and size of each
+    word is recorded in the corresponding .idx file.
+
+    If the "sametypesequence" option is not used in the .ifo file, then
+    the .dict file has fields in the following order:
+    ==============
+    word_1_data_1_type; // a single char identifying the data type
+    word_1_data_1_data; // the data
+    word_1_data_2_type;
+    word_1_data_2_data;
+    ...... // the number of data entries for each word is determined by
+           // word_data_size in .idx file
+    word_2_data_1_type;
+    word_2_data_1_data;
+    ......
+    ==============
+    It's important to note that each field in each word indicates its
+    own length, as described below.  The number of possible fields per
+    word is also not fixed, and is determined by simply reading data until
+    you've read word_data_size bytes for that word.
+
+
+    Suppose the "sametypesequence" option is used in the .idx file, and
+    the option is set like this:
+    sametypesequence=tm
+    Then the .dict file will look like this:
+    ==============
+    word_1_data_1_data
+    word_1_data_2_data
+    word_2_data_1_data
+    word_2_data_2_data
+    ......
+    ==============
+    The first data entry for each word will have a terminating '\0', but
+    the second entry will not have a terminating '\0'.  The omissions of
+    the type chars and of the last field's size information are the
+    optimizations required by the "sametypesequence" option described
+    above.
+
+    If "idxoffsetbits=64", the file size of the .dict file will be bigger 
+    than 4G. Because we often need to mmap this large file, and there is 
+    a 4G maximum virtual memory space limit in a process on the 32 bits 
+    computer, which will make we can get error, so "idxoffsetbits=64" 
+    dictionary can't be loaded in 32 bits machine in fact, StarDict will 
+    simply print a warning in this case when loading. 64-bits computers 
+    should haven't this limit.
+
+    Type identifiers
+    ----------------
+    Here are the single-character type identifiers that may be used with
+    the "sametypesequence" option in the .idx file, or may appear in the
+    dict file itself if the "sametypesequence" option is not used.
+
+    Lower-case characters signify that a field's size is determined by a
+    terminating '\0', while upper-case characters indicate that the data
+    begins with a network byte-ordered guint32 that gives the length of 
+    the following data's size(NOT the whole size which is 4 bytes bigger).
+
+    'm'
+    Word's pure text meaning.
+    The data should be a utf-8 string ending with '\0'.
+
+    'l'
+    Word's pure text meaning.
+    The data is NOT a utf-8 string, but is instead a string in locale
+    encoding, ending with '\0'.  Sometimes using this type will save disk
+    space, but its use is discouraged.
+
+    'g'
+    A utf-8 string which is marked up with the Pango text markup language.
+    For more information about this markup language, See the "Pango
+    Reference Manual."
+    You might have it installed locally at:
+    file:///usr/share/gtk-doc/html/pango/PangoMarkupFormat.html
+
+    't'
+    English phonetic string.
+    The data should be a utf-8 string ending with '\0'.
+
+    Here are some utf-8 phonetic characters:
+    θʃŋʧðʒæıʌʊɒɛəɑɜɔˌˈːˑṃṇḷ
+    æɑɒʌәєŋvθðʃʒɚːɡˏˊˋ
+
+    'x'
+    A utf-8 string which is marked up with the xdxf language.
+    See http://xdxf.sourceforge.net
+    StarDict have these extention:
+    <rref> can have "type" attribute, it can be "image", "sound", "video" 
+    and "attach".
+    <kref> can have "k" attribute.
+
+    'y'
+    Chinese YinBiao or Japanese KANA.
+    The data should be a utf-8 string ending with '\0'.
+
+    'k'
+    KingSoft PowerWord's data. The data is a utf-8 string ending with '\0'.
+    It is in XML format.
+
+    'w'
+    MediaWiki markup language.
+    See http://meta.wikimedia.org/wiki/Help:Editing#The_wiki_markup
+
+    'h'
+    Html codes.
+
+    'r'
+    Resource file list.
+    The content can be:
+    img:pic/example.jpg     // Image file
+    snd:apple.wav           // Sound file
+    vdo:film.avi            // Video file
+    att:file.bin            // Attachment file
+    More than one line is supported as a list of available files.
+    StarDict will find the files in the Resource Storage.
+    The image will be shown, the sound file will have a play button.
+    You can "save as" the attachment file and so on.
+
+    'W'
+    wav file.
+    The data begins with a network byte-ordered guint32 to identify the wav
+    file's size, immediately followed by the file's content.
+
+    'P'
+    Picture file.
+    The data begins with a network byte-ordered guint32 to identify the picture
+    file's size, immediately followed by the file's content.
+
+    'X'
+    this type identifier is reserved for experimental extensions.

 4. The online reading page is optimized for e-ink screens, using pagination instead of scrolling. The page is divided into 5 clickable areas:
-   * Top left corner: Previous article

+2. KindleEar also supports offline dictionaries in the stardict format. After downloading the corresponding dictionary, unzip it into the `data/dict` directory. You can organize different dictionaries into subdirectories. Then, restart the KindleEar service to refresh the dictionary list.    
+3. By default, American English morphology queries are supported.
