+## What is it
+The GC Knobs client allows you to make bulk requests to GC Knobs
+
+## How to use 
+clone and start https://github.com/MikeMitchellWebDev/gc_knobs.git
+
+clone and run gc_knobs_client like this
+
+./gc_knobs_client -g 200 -s 1 -r 10 -p "/Users/mm/rails"
+
+This commmand will read a locally cloned copy of ruby on rails into memory
+2000 times (spawning 200 go routines, each making the request 10 times with a sleep of 1 second between each request)
+
+
+-g is the number of goroutines
+-s is the sleep duration between requests
+-r is the number of repeats
+-p is the path to the locally cloned repository
+
+You don't need the gc_knobs_client to use gc_knobs. You can also use gc_knobs with curl
+
+curl -H 'Content-Type: application/json' -d '{"path":"/path/to/rails", "repeat":"50", "sleep":"2"}' -X POST  http://localhost:8000/git_repo
