+h2. Re-using your pipeline run
+
+Arvados allows users to re-use jobs that have the same inputs in order to save computing time and resources. Users are able to change a job downstream without re-computing earlier jobs. This section shows which version control parameters should be tuned to make sure Arvados will not re-compute your jobs.
+
+Note: Job reuse can only happen if all input collections do not change.
+
+* @"arvados_sdk_version"@ : The arvados_sdk_version parameter is used to download the specific version of the Arvados sdk into the docker image. The latest version can be found in the "Arvados Python sdk repository":https://dev.arvados.org/projects/arvados/repository/revisions/master/show/sdk/python under *Latest revisions*. Make sure you set this to the same version as the previous run that you are trying to reuse.
+* @"script_version"@ : The script_version is the commit hash of the git branch that the crunch script resides in. This information can be found in your git repository by using the following command:
+
+<notextile>
+<pre><code>~$ <span class="userinput">git rev-parse HEAD</span></code></pre>
