 # splitappendix
 A simple shellscript for splitting the PDF of a paper into the main body and an appendix.
+
+This isn't exactly rocket science, but it's something I have to do frequently enough when submitting academic papers that I figured it's worth semi-automating. Hopefully you find it saves you a few minutes each time too!
+
+## Installation
+
+Simply clone the repo, move/rename the script to your somewhere on your `$PATH`, and make it executable. For example:
+
+```bash
+git clone [email protected]:egrefen/splitappendix.git
+cd splitappendix
+chmod +x splitappendix.sh
+echo ln -s `pwd`/splitappendix.sh ~/.local/bin/splitapp
+```
+
+## Usage
+
+```bash
+splitapp path_to_paper.pdf first_page_of_appendix
+```
+
+This assumes you've named the script `splitapp` and put it in your path.
+Once run, the files `submission.pdf` and `appendix.pdf` will be put in the same directory as the target paper.
