+### Source Cooperative
+
+[Source Cooperative](https://source.coop) is a publishing utility for open data operated by [Radiant Earth](https://radiant.earth/).
+
+To upload PMTiles to Source Cooperative, use the [pmtiles cli](/pmtiles/cli).
+
+On the **Manage** page of your source.coop repository, create an API key and find the **Access Key ID** and **Secret Access Key**.
+
+Then use `pmtiles upload` to copy the file to Source's S3-compatible endpoint:
+
+```sh
+export AWS_ACCESS_KEY_ID=YOUR_KEY
+export AWS_SECRET_ACCESS_KEY=YOUR_SECRET
+pmtiles upload file.pmtiles path/in/bucket/key.pmtiles --bucket=s3://ORGANIZATION_NAME?endpoint=https://data.source.coop&region=auto&use_path_style=true
