# Setting up a practice repository
We will create a new git repository and import a library of existing
tool definitions that will help us build our workflow.

+
+When using the recommended VSCode environment to develop on Arvados, start by forking this repository:
+```
+git clone https://github.com/arvados/arvados-vscode-cwl-template.git rnaseq-cwl-training-exercises
+```
+{: .language-bash }
+
+Next, import bio-cwl-tools with this command:

+> You can check by going to Workbench and pasting
+> `9178fe1b80a08a422dbe02adfd439764+925` into the search box. If you
+> arrived at a collection page instead of a "not found" error, then
+> you do not need to perform this download step.
+{: .callout}
+
+Use `arv-copy` to copy the collection:
+
+```
+arv-copy --src jutro 9178fe1b80a08a422dbe02adfd439764+925
+```
+{: .language-bash }
+# Downloading or generating STAR index
+
+Running STAR requires index files generated from the reference.
+
+This is a rather large download (4 GB). Depending on your bandwidth, it may be faster to generate it yourself.
