-This guide covers a common subset of tasks that a user would need to perform to have a set of clustered computer instances and associated resources, isolated from others, and accessible to a project for any general purpose, both long-term and short. We are catering heavily to short-term and periodic usage, perhaps lasting no more than a few quarters.+This guide covers the common subset of tasks that users would need to perform to have a set of clustered computer instances and associated resources, isolated from others, and accessible to a project for any general purpose, both long-term and short.

 Use your favorite package manager on your own computer. Pip is preferred because the upstream packages it for themselves and it is in pure python. The general CS infrastructure will become a managed client for you to use in the near future (e.g., linux.cs.uchicago.edu). However, our experience has been that the software installs cleanly and is free from dependency problems. Use your favorite package manager on your own computer.

 After creating your own network and subnet(s), a router is also needed. However, a router is **not** needed if your instances only talk to each other. The router will take the gateway of your subnet automatically, and allow clients to access the internet via outbound NAT. Much more is possible, and a router is a prerequisite for the next step, which is inbound NAT (DNAT). After creating your own network and subnet(s), a router is also needed.
