+:::note[📦 Crate]
+
+The SDK is provided by the [junobuild-satellite](https://docs.rs/junobuild-satellite/latest/junobuild_satellite/index.html) crate.
+
+To use them, add this to your Cargo.toml:
+
+```toml
+[dependencies]
+junobuild-satellite = "*"
+```
+
+You have to follow the pace of the Juno release to ensure compatibility. Refer to the [maintenance guide](../../../build/functions/development/rust.mdx#maintenance) for instructions.

+    key: Key,
+    value: SetDoc,
+) -> Result<DocContext<DocUpsert>, String>
