 ## Pipeline
 
-```
-STAC item URL → Extract zarr → Convert (Dask) → S3 → Register STAC + TiTiler → Done (~15-20 min)
-```
+**Flow:** STAC item URL → Extract zarr → Convert to GeoZarr → Upload S3 → Register STAC item → Add visualization links
 
-**Steps:**
-1. **Convert** - Fetch STAC item, extract zarr URL, convert to GeoZarr, upload to S3
-2. **Register** - Create STAC item with TiTiler preview links, register to catalog
+**Processing:**
+1. **convert.py** - Fetch STAC item, extract zarr URL, convert to cloud-optimized GeoZarr, upload to S3
+2. **register.py** - Create STAC item with asset hrefs, add projection metadata and TiTiler links, register to catalog
 
-**Stack:** Argo Workflows • [eopf-geozarr](https://github.com/EOPF-Explorer/data-model) • Dask • RabbitMQ • Kustomize
+**Runtime:** ~15-20 minutes per item

+**Stack:**
+- Orchestration: Argo Workflows, Kustomize
+- Processing: eopf-geozarr, Dask, Python 3.13
+- Storage: S3 (OVH)
+- Catalog: pgSTAC, TiTiler
+- Events: RabbitMQ
