+Ruff provides a pop-up web server to Retrieve/Upload Files Fast over LAN,
+inspired by WOOF (Web Offer One File) by Simon Budig.
+
+It's based on the idea that not every device has <insert neat file transfer
+tool here>, but just about every device that can network has an HTTP client,
+making a hyper-simple HTTP server a viable option for file transfer with
+zero notice or setup as long as *somebody* has a copy of RUFF.
+
+Why create RUFF when WOOF exists? WOOF is no longer in the debian repos and
+it's easier to `go get` a tool than it is to hunt down Simon's website for
+the latest copy.
+
+## Installation
+
+`go get git.tilde.town/diff/ruff`
+
+## Usage
+
+Assuming $GOPATH is in $PATH:
+
+`ruff "cool thing.jpg" # to send a cool file`
+
+and
+
+`ruff -u # to receive a cool file`
