 The Recorder is a tool used to save a bunch of transactions in a JSON file and
 rerun them later either in the same environment or in another.

 There are many use cases for the recorder.  
 
 For instance:
 
 -   After having coded and tested contracts in a constrained
-    environment (like the JavaScript VM), you could then change the environment and redeploy it to a more realistic environment like a test net with an **injected web3** or to a Geth node. By using the generated **senario.json** file, you will be using all the same settings that you used in the Javascript VM.  And this mean that you won't need to click the interface 100 times or whatever to get the state that you achieved originally.  So the recorder could be a tool to protect your sanity.

-To create this file in the recorder, you first of course need to have run some transactions.  In the image above - it has a `0` next to **Transactions Recorded**.  So this isn't the right moment to save transactions because - well because there aren't any.  Each time you make a transaction, that number will increment.  Then when you are ready, click the floppy disk icon and the senario.json file will be created.
