 The script is fetched from IPFS, and is executed by one or several Bacalhau nodes.
 After the computation is finished, the results (the numbers printed) are published to IPFS, with a new CID, `QmFH...`.
 
+## Why Is It Important?
+
+* Sometimes, **you need to perform tasks that are heavy in computational terms**, and you may not have the right hardware to execute them.
+The Bacalhau network **provides you with a wide range of machines and resources** that you can use to run your computations.
+
+* Bacalhau offers **built-in integration** with IPFS.
+You can use IPFS files and folders as an input in your computations, and the results are stored in IPFS.
+
+* In the future, running heavy computations might not be free.
+However, Bacalhau **nodes have the ability to bid for executing computations**, thus creating a market where supply and demand can offer really competitive prices.

 ## Architecture
 
 Every node in the Bacalhau network can act as a _requester node_ or a _compute node_.
