+## CBconvert
-=========
 
-Introduction
+### Introduction
-------------
 
 CBconvert is a [Comic Book](http://en.wikipedia.org/wiki/Comic_Book_Archive_file) converter.
-It allows you to convert individual comics or bulk convert comics to different formats to fit your various devices.
 
-Features
+It can convert comics to different formats to fit your various devices.
---------
 
- - reads RAR, ZIP, 7Z, GZ, BZ2, CBR, CBZ, CB7, CBT, PDF, EPUB, XPS and plain directory
+### Features
- - always saves processed comic in CBZ (ZIP) archive format
- - images can be converted to JPEG, PNG, GIF, TIFF or 4-Bit BMP (16 colors) file format
- - choose resize algorithm (NearestNeighbor, Box, Linear, MitchellNetravali, CatmullRom, Gaussian, Lanczos)
- - rotate, flip, adjust brightness/contrast or grayscale images
- - export covers from comics
- - create thumbnails from covers by [freedesktop](http://www.freedesktop.org/wiki/) specification

+```
 
-[BMP](http://en.wikipedia.org/wiki/BMP_file_format) format is very good choice for black&white pages. Archive size can be smaller 2-3x and file will be readable by comic readers.
+### Examples
 
-Generate thumbnails by freedesktop specification in ~/.thumbnails/normal directory with width 512:
+* Rescale images to 1200px for all supported files found in a directory with a size larger than 60MB:
 
-    cbconvert thumbnail --width 512 --outdir ~/.thumbnails/normal /media/comics/GrooTheWanderer/
+`cbconvert --recursive --width 1200 --size 60 /media/comics/Thorgal/`
 
-Extract covers to ~/covers dir for all supported files found in directory, Lanczos algorithm is used for resizing:
+* Convert all images in pdf to 4bit BMP images and save the result in ~/comics directory:
 
-    cbconvert cover --outdir ~/covers --filter=7 /media/comics/GrooTheWanderer/
+`cbconvert --format bmp --outdir ~/comics /media/comics/Garfield/Garfield_01.pdf`
