# Publishing an existing collection

### Publishing through CSPR.studio

If your NFT collection was created outside of CSPR.studio you can still use it to publish your collection to CSPR.market.

Note: You can also create a new collection on CSPR.studio, see details [here](/create-your-collection.md#creating-an-nft-collection).

### First register your existing collection

* Navigate to [CSPR.studio](https://cspr.studio) > [My Collections](https://cspr.studio/collections)
* Click [Create new collection](https://cspr.studio/new-collection)
