+The files/directories under the root of CSAR include:
+
+* **TOSCA-Metadate** is a directory which contains **TOSCA.meta** file, the metadata regarding the CSAR structure.
+* **Artifacts** is a directory which contains all the recoginzable artifacts (except those of type *Other*). All the artifacts are further classified as either *Informational* or *Deployment*, and are located in the sub-directories respectively. Artifacts located in the root directory or un-recognized folders will be classified as *Other*.
+* **Resources** is a directory which contains a sub-directory **node_template <name>** per each node_template that has specific artifacts (artifacts that were added to the instance/customized for the instance or generated for the instance. This folder should **NOT** include artifacts of the type of the instance. (e.g. HEAT should be in the folder of the VF and not in the folder of the VF instance, HEAT_ENV will be in the folder of the instance.)
+* **Definitions** is a directory which contains all the TOSCA yaml files.
+
+The files/directories under the *Artifacts* directory further include:
+
+* **Informational** directory which holds all the informative artifacts supported directly by SDC.
+* **Deployment** directory which holds all the deployment artifacts supported directly by SDC.
+* (Optional) **VFC TOSCA <name>** directory for each VFC (i.e. VF Component) which holds all the artifacts for the VFC **<name>**.
+
+The files/directories under each **VFC TOSCA <name>** sub-directory further include:
+
+* **Informational** directory which holds all the informative artifacts at the VFC level.
+* **Deployment**  directory which holds all the deployment artifacts at the VFC level.
