# Installation ## Choosing the Installation Location VirtualFlow should be installed on a **fast shared scratch file system**, rather than the home directory (which is often slow and/or has insufficient I/O capacities). After having chosen the installation location, go to the directory were you want VFVS and the workflow files to be stored: ``` cd ``` \[For more information about the installation location, see the [*corresponding section*](https://docs.virtual-flow.org/documentation/-LdE8RH9UN4HKpckqkX3/installation/vflp#installation-location) in the documentation.] ## Installing VFVS The tutorial files can be downloaded with the `wget` command: ``` wget https://github.com/VirtualFlow/VFVS/archive/refs/heads/vfvs-1.tar.gz ``` Then, the files can be extracted with: ``` tar -xvzf vfvs-1.tar.gz ``` Then we can rename the directory to something more meaningful. In our case we choose as name `VFVS_GK` (for glucokinase), since this is the target we will use: ``` mv VFVS-vfvs-1 VFVS_GK ``` \[For more information about installing VirtualFlow in general, see the [*corresponding section*](https://docs.virtual-flow.org/documentation/-LdE8RH9UN4HKpckqkX3/installation/vflp#tarball-installation) in the documentation.] --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
