+Details
+-------
+
+Etip will be usually invoked when EDE is started, and if you don't want 
+this, you can always uncheck 'Show tips at startup' checkbox.
+
+Etip will read tips from fortune-like file, which is based on two parts:
+
+   * file with tips
+   * a companion with *.dat* extension
+
+File with tips is plain text file in human readable form and is main source where
+you should add, changed and delete tips. Each tip is separated with *%* character
+at the beginning of the line, and (as advice), those should be nicely formatted
+(proposal is to use around 66 characters per line so they can nicely fit inside
+etip window).
+
+*.dat* file is binary file and does not contain any tip strings; it have only
+offsets to those in plain text file to allow fast random access to any of
+specific tip string. *.dat* files are created with 'etip-compiler' command (see bellow
+for the details), and must be updated each time when a source file with tips is updated.
+
+[NOTE]
+Both files must exists so etip can read the content.
+
+Example
+-------
+
+Let we as example create simple tip file, named 'demo' with some content.
+
+--------------
+This is tip one.
+%
+This is tip two. Nice.
+%
+This is tip three. Progress, man, progress :)
+%
+--------------
+
+[NOTE]
+Please let end line in each tip contains *%* character. With this we retain a small
+compatibility with fortune
+
+Now save this file in 'demo' and invoke 'etip-compiler' on it. Doing that is like:
+--------------
+etip-compiler demo
+--------------
+
+You will see output like this:
+--------------
+"demo.dat" created
+There were 3 strings
+Longest string: 46 bytes
+Shortest string: 17 bytes
+--------------
+
+Output from 'etip-compiler' shows some informations you probably don't need and, most important,
+it shows that he created *demo.dat* file. If you want to suppress these outputs, just
+use '-s' flag, like:
+
+--------------
+etip-compiler -s demo
+--------------
+
+'etip-compiler' will, by default, use input name and append *.dat* suffix; the best way is to keep
+it like that since etip expects names of tip file and .dat file are the same (or will not be able
+to find .dat file). 'etip-compiler' have some more options, and for the details see below.
+
+Configuration
+-------------
+
+Etip does not have command options and the only file it reads (beside tip files) is 'etip.conf'.
+This file should contain path to the tip file name. Here is the sample:
+
+--------------
+[etip]
+ Path = /usr/share/ede/tips/ede
+--------------
+
+[NOTE]
+Make sure in the same directory exists *.dat* file.
+
+
+etip-compiler details
+---------------------
+
+As you could see from the previous text, 'etip-compiler' is simple command line tool that will
+create .dat files. It will correctly scan tip file, calculate offsets (and something more) and spit
+that in the file that etip understands.
+
+[NOTE]
+You must invoke etip-compiler each time you change file with the tips or .dat companion will contains
+incorrect data.
