+For example, let's copy from the <a href="https://playground.arvados.org/">Arvados playground</a>, also known as *pirca*, to *dstcl*. The names *pirca* and *dstcl* are interchangable with any cluster id. You can find the cluster name from the prefix of the uuid of the object you want to copy. For example, in *zzzzz*-4zz18-tci4vn4fa95w0zx, the cluster name is *zzzzz* .
+
+In order to communicate with both clusters, you must create custom configuration files for each cluster. The "Getting an API token":{{site.baseurl}}/user/reference/api-tokens.html page describes how to get a token and create a configuration file. However, instead of "settings.conf" in @~/.config/arvados@ you need two configuration files, one for each cluster, with filenames in the format of *ClusterID.conf*.
+
+In this example, navigate to the *Current token* page on each of *pirca* and *dstcl* to get the @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@.
+
+The config file consists of two lines, one for ARVADOS_API_HOST and one for ARVADOS_API_TOKEN:
+
+<pre>
+ARVADOS_API_HOST=zzzzz.arvadosapi.com
+ARVADOS_API_TOKEN=v2/zzzzz-gj3su-xxxxxxxxxxxxxxx/123456789abcdefghijkl
+</pre>
+
+Copy your @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ into the config files as shown below in the shell account from which you are executing the commands. In our example, you need two files, @~/.config/arvados/pirca.conf@ and @~/.config/arvados/dstcl.conf@.
+
+Now you're ready to copy between *pirca* and *dstcl*!
+
+h3. How to copy a collection
+
+First, determine the uuid or portable data hash of the collection you want to copy from the source cluster. The uuid can be found in the collection display page in the collection summary area (top left box), or from the URL bar (the part after @collections/...@)
+
+Now copy the collection from *pirca* to *dstcl*. We will use the uuid @jutro-4zz18-tv416l321i4r01e@ as an example. You can find this collection on <a href="https://playground.arvados.org/collections/jutro-4zz18-tv416l321i4r01e">playground.arvados.org</a>.
