+## About Calibration
+
 Prospective storage providers can experience more realistic sealing performance and hardware requirements using final proofs constructions and parameters. Storage clients can store and retrieve _real data_ on the network. Clients can also participate in deal-making workflows and storage and retrieval functionality. The sector size on the Calibration testnet is the same as on the Filecoin mainnet; 32 GiB and 64 GiB sectors are supported. This testnet also includes the Filecoin EVM-runtime features found on the Filecoin mainnet.
 
 Developers can reference pre-existing deals that are already available on the network. See the [`#fil-net-calibration-discuss` channel in the Filecoin Slack](https://filecoinproject.slack.com/archives/C01D42NNLMS) for support.
