A **deployed** subgraph is free to use, rate-limited, not visible to the public, and meant to be used for development, staging, and testing purposes.

 ### 7. Publish your subgraph to The Graph Network
 
-Publishing a subgraph to the decentralized network is an onchain action that makes your subgraph available for [Curators](/resources/roles/curating/) to curate it and [Indexers](/indexing/overview/) to index it.
+When your subgraph is ready for a production environment, you can publish it to the decentralized network. Publishing is an onchain action that does the following:
+
+- It makes your subgraph available to be to indexed by the decentralized [Indexers](/indexing/overview/) on The Graph Network.
+- It removes rate limits and makes your subgraph publicly searchable and queryable in [Graph Explorer](https://thegraph.com/explorer/).
+- It makes your subgraph available for [Curators](/resources/roles/curating/) to curate it.
+
+> The greater the amount of GRT you and others curate on your subgraph, the more Indexers will be incentivized to index your subgraph, improving the quality of service, reducing latency, and enhancing network redundancy for your subgraph.
