+## Categories, tags and language
+
+Keywords come from a controlled vocabulary, defined in [`schema.json`](scripts/src/ecosystem_scripts/schema.json) and validated in CI.
+It overlaps with the vocabulary used by the [tutorial registry](https://github.com/scverse/scverse-tutorials/blob/main/tutorial-registry/schema.json).
+
+`primary_category` is the single category your package is listed under on [scverse.org/packages](https://scverse.org/packages/#ecosystem).
+Pick the one a user looking for your package would browse first.
+
+- `Data structures`
+- `scRNA-seq`
+- `bulk RNA-seq`
+- `Spatial`
+- `Epigenomics`
+- `Proteomics`
+- `Adaptive immune cell receptor`
+- `Multimodal`
+- `Imaging`
+- `Infrastructure`
+
+`tags` say what the package does, and drive filtering and search on the website.
+Pick every tag that genuinely applies.
+
+- **Data and modality** — `scRNA-seq`, `bulk RNA-seq`, `spatial transcriptomics`, `spatial proteomics`, `proteomics`, `flow cytometry`, `ATAC-seq`, `epigenomics`, `immune receptor`, `imaging`, `multimodal`
+- **Analysis step** — `preprocessing`, `quality control`, `denoising`, `data integration`, `cell-type annotation`, `differential expression`, `compositional analysis`, `functional analysis`, `gene regulatory networks`, `cell-cell communication`, `deconvolution`, `clustering`, `dimensionality reduction`, `trajectory inference`, `pseudotime`, `RNA velocity`, `lineage tracing`, `perturbation`, `spatially variable genes`, `segmentation`, `copy number variation`, `visualization`, `benchmarking`
+- **How it is built** — `deep learning`, `foundation model`, `large language models`, `probabilistic modeling`, `optimal transport`, `GPU acceleration`, `pipeline`
+- **Project shape** — `data structures`, `interoperability`, `file formats`, `documentation`
+
+If none of the existing terms fit your package, add one to the enum in your pull request.
+
+`language` is the language you write in when using the package: `Python`, `R`, `Julia` or `Rust`.

 Ecosystem packages can be written in non-Python languages as long as they fulfill the above requirements.

 If you cannot or do not want to comply with these requirements, you are still free to make your package interoperable with scverse by using our datastructures, but we will not list your package on our ecosystem page.
