-7. Generate checksum files (with the checksum and the file name) for source and binary files
-
-.. code-block:: bash
-
-  sha512sum apache-crail-${RELEASE_VERSION}-incubating-src.tar.gz > apache-crail-${RELEASE_VERSION}-incubating-src.tar.gz.sha512
-  sha512sum apache-crail-${RELEASE_VERSION}-incubating-bin.tar.gz > apache-crail-${RELEASE_VERSION}-incubating-bin.tar.gz.sha512
-
-**NOTE:** step 7 will be automated once the [JIRA-56](https://issues.apache.org/jira/projects/CRAIL/issues/CRAIL-56) is fixed.
