+`pdfstitch` does a similar job to `pdfnup` but focuses on the following features:
 
 * Crop pages to a certain size
 * Adjust the crop position per page
 
+## License
+`pdfstitch` is free software under the GNU AGPL version 3. See `LICENSE` for details.
+
 ## Dependencies
 
 `pdfstitch` makes use of the following Perl modules:
 
 * File::Basename (part of perl base)
+* File::LibMagic
+* Getopt::Long (part of perl base)
 * PDF::API2
 * YAML
 
 On Debian, you can installed them with:
 
-`# apt install libpdf-api2-perl libyaml-perl`
+`# apt install libfile-libmagic-perl libpdf-api2-perl libyaml-perl`
 
 ## Usage
 
-1. Run `genmeta` on your input PDF like so:
+1. Run `pdfstitch` on your input PDF:
 
-   `./genmeta foobar.pdf`
+   `./pdfstitch [--genmeta] foobar.pdf`
 
    This will generate a YAML file called `foobar.pdf.stitch`. Edit this file according to the desired output.
-2. Optional: Run `genpreview` on that YAML file like so:
+   This is also the default action if called with a PDF.
+2. Optional: Generate a preview and/or cropped PDF:
+
+   `./pdfstitch --preview foobar.pdf.stitch`
+
+   This will generate a new PDF called `foobar-preview.pdf`.
+   It contains only the pages you select in the YAML file with each page being overlayed with a transparent box
+   showing the are the page will be cropped to.
+
+   `./pdfstitch --crop foobar.pdf.stitch`
+
+   This will generate a new PDF called `foobar-cropped.pdf`.
+   It contains only the pages you select in the YAML file with each page being cropped accordingly.
+4. Generate the final stitched PDF:
 
-   `./genpreview foobar.pdf.stitch`
+   `./pdfstitch --stitch foobar.pdf.stitch`
 
-   This will generate a new PDF called `foobar-preview.pdf` containing only the pages you selected
-   in the YAML file with each page being overlayed with a transparent box showing the area the
-   page will be cropped to.
+   This will generated a single-page PDF called `foobar-stitched.pdf` with all selected pages being
+   stitched together as specified in the YAML file.
+   This is also the default action if called with just a meta file.
 
-3. Optional: Run `gencropped` on the YAML file. This will generate a new PDF called `foobar-cropped.pdf` containing
-   only the pages you selected in the YAML file with each page being cropped as specified.
-4. Run `pdfstitch` on the YAML file. This will generated a single-page PDF called `foobar-stitched.pdf` with all
-   selected pages being as specified in the YAML file.
+## Notes
 
+* The output file name is based on the .stitch file name.
+* All output files are placed in the current working directory.
