+== Overview
+
+Initially, I just wanted a server that I could upload images to, and quickly
+serve back. While it's mostly that, it is the client and server side tooling.
+
+The files are stored in mongoDB, using its GridFS.
+
+== Usage
+
+Server side
+For a basic start, make sure mongo is running on the localhost, and run:
+  ./imgsrv -server
+  2013/02/12 13:03:37 0.0.0.0
+  2013/02/12 13:03:37 Serving on 0.0.0.0:7777 ...
+
+For something a bit more complicated, like an openshift diy-0.1 cartridge, 
+set your .openshift/action_hooks/start to:
+  nohup ${OPENSHIFT_REPO_DIR}/bin/server \
+    -server \
+    -ip ${OPENSHIFT_INTERNAL_IP} \
+    -port 8080 \
+    -mongo-host ${OPENSHIFT_NOSQL_DB_URL} \
+    >> ${OPENSHIFT_LOG_DIR}/server.log 2>&1 &
+
+
+Client side:
+Either pass the -remotehost flag pointing to your server instance
+
+  imgsrv -remotehost http://hurp.til.derp.com:7777 -put ./lolz.gif -keywords 'cats,lols'
+
+
+or setup your ~/.imgsrv.yaml, with a the value 'remotehost', like so:
+  ---
+  remotehost: http://hurp.til.derp.com:7777
+
+then you can drop that flag out, for quicker lolzing:
+
+  imgsrv -put ./lolz.gif -keywords 'cats,lols'
