 # mergepdf
 
-FIXME: description
+Simple personal commandline utility to merge all pdfs in a directory. Only tested on OSX, built using lein-bin. Built because I often find myself with a directory full of PDFs (chapters of bigger writing project, anonymized student work that needs to be compiled and shared, etc.) that need to be merged and it's an annoying hassle to do it with big icky GUI apps or web services.
 
 ## Installation
 
-Download from http://example.com/FIXME.
+Download the binary merge-pdfs either in the root directory here or from the releases page.  Stick it on your path. Make it executable. 
 
-## Usage
-
-FIXME: explanation
-
-    $ java -jar mergepdf-0.1.0-standalone.jar [args]
-
-## Options
+(or use one of the JAR files, or build it yourself, or whev.)
 
-FIXME: listing of options this app accepts.
+## Usage
 
-## Examples
+    $ merge-pdfs outfile.pdf
 
-...
+will take every PDF in the directory you run it from and merge them into a file called output.pdf
 
-### Bugs
+it's basically alphabetical order, I think it goes in the order that directory listings show up in.

+## Options
 
-### Any Other Sections
-### That You Think
-### Might be Useful
