+### Adding Tessera artefacts
+
+Download and unpack the artefact:
+
+```shell
+$ tar xvf aws-key-vault-[version].tar
+$ tree aws-key-vault-[version]
+aws-key-vault-[version].tar
+└── lib
+    ├── annotations-2.10.25.jar
+    ...
+```
+
+Copy the contents of the artefact's `/lib` into the distribution `/lib` (make sure to resolve any version conflicts/duplicated `.jar` files introduced during the copy):
+
+```shell
+ cp -a aws-key-vault-[version]/lib/. tessera-[version]/lib/
+```
