:::{grid-item-card} {octicon}`rocket;1.5em;sd-mr-1` Quickstart: Single Sample
:link: notebooks/zero_shot_quickstart
:link-type: doc

Embed one spatial sample with a pretrained model and identify cell types and
spatial niches.
:::

:::{grid-item-card} {octicon}`stack;1.5em;sd-mr-1` Quickstart: Multiple Samples
:link: notebooks/zero_shot_quickstart_multisample
:link-type: doc

Embed several sections/donors together and integrate them into a shared space.
