-Introduction
+### Introduction
-------------
 
-CBconvert is a [Comic Book](http://en.wikipedia.org/wiki/Comic_Book_Archive_file) convert tool.
+CBconvert is a [Comic Book](http://en.wikipedia.org/wiki/Comic_Book_Archive_file) converter.
+
+It can convert comics to different formats to fit your various devices.
+
+### Features
+
+* reads RAR, ZIP, 7Z, CBR, CBZ, CB7, CBT, PDF, EPUB, MOBI and plain directory
+* saves processed comics in CBZ (ZIP) archive format or CBT (TAR)
+* images can be converted to JPEG, PNG, TIFF, WEBP, AVIF, or 4-Bit BMP (16 colors) file format
+* rotate, flip, adjust brightness/contrast, adjust levels (Photoshop-like) or grayscale images
+* resize algorithms (NearestNeighbor, Box, Linear, MitchellNetravali, CatmullRom, Gaussian, Lanczos)
+* export covers from comics
+* create thumbnails from covers by [FreeDesktop](http://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html) specification
+
+### Download
+
+* [Windows x86_64](https://github.com/gen2brain/cbconvert/releases/latest/download/cbconvert-0.8.3-windows-x86_64.zip)
+* [Linux x86_64](https://github.com/gen2brain/cbconvert/releases/latest/download/cbconvert-0.8.3-linux-x86_64.tar.gz)
+* [Linux aarch64](https://github.com/gen2brain/cbconvert/releases/latest/download/cbconvert-0.8.3-linux-aarch64.tar.gz)
+* [macOS x86_64](https://github.com/gen2brain/cbconvert/releases/latest/download/cbconvert-0.8.3-darwin-x86_64.zip)
+* [macOS aarch64](https://github.com/gen2brain/cbconvert/releases/latest/download/cbconvert-0.8.3-darwin-aarch64.zip)
+
+### Using cbconvert in file managers to generate FreeDesktop thumbnails
+
+Copy cbconvert cli binary to your PATH and create file ~/.local/share/thumbnailers/cbconvert.thumbnailer:
+
+```
+[Thumbnailer Entry]
+TryExec=cbconvert
+Exec=cbconvert thumbnail --quiet --width %s --outfile %o %i
+MimeType=application/pdf;application/x-cb7;application/x-cbt;application/epub+zip;application/vnd.comicbook-rar;application/vnd.comicbook+zip;application/x-mobipocket-ebook;
+```
+
+This is what it looks like in the PCManFM file manager:

+### Examples
+
+Rescale images to 1200px for all supported files found in a directory with a size larger than 60MB:
+
+`cbconvert --recursive --width 1200 --size 60 /media/comics/Thorgal/`
+
+Convert all images in pdf to 4bit BMP images and save the result in ~/comics directory:
+
+`cbconvert --bmp --outdir ~/comics /media/comics/Garfield/Garfield_01.pdf`
+
+[BMP](http://en.wikipedia.org/wiki/BMP_file_format) format is a very good choice for black&white pages. Archive size can be smaller 2-3x and the file will be readable by comic readers.
+
+Extract covers to ~/covers dir for all supported files found in the directory, Lanczos algorithm is used for resizing:
+
+`cbconvert cover --outdir ~/covers --filter=7 /media/comics/GrooTheWanderer/`
+
+### Compile
+
+Install ImageMagick7 and libheif (with libaom) libraries and headers and then install to GOBIN:
+
+`go install github.com/gen2brain/cbconvert/cmd/cbconvert@latest`
