For now, only users with permissions for this repository can add/delete datasets. If you don't have the permissions but want to add a dataset, open an issue to discuss with us.

## Git-LFS setup

Before adding a dataset, make sure you have setup [`git-lfs`](https://git-lfs.com/).

## Adding a dataset

1. Add one/multiple `.h5ad` file(s) under the right directory, according to the right `species` and `tissue`. E.g., `human/breast/filename.h5ad`. Each file corresponds to one slide.
2. Fill the corresponding metadata under `metadata.csv`
3. Just commit files as usual. `git-lfs` will handle it.
