 # Uploading data to lincbrain.org
 **Note:** The steps below require access to https://lincbrain.org, which is a private repository for LINC project investigators.
 
-## Create a new dataset
-A dataset refers to a collection of brains that have been processed and imaged in a similar way. It typically contains data from multiple brains or samples, possibly imaged with multiple modalities. Log into lincbrain.org and click on the `NEW DATASET` button at the top right of the page. Fill out the title, description, and license. (The license option exists only because lincbrain.org is a clone of DANDI. It has no effect here, as lincbrain.org is a private repository.) Click on the `REGISTER DATASET` button to create the new dataset.
