## Connecting to JupyterHub
-----------------------
Jupyter defines it's notebooks ("Jupyter Notebooks") as
an open-source web application that allows you to create and share documents that contain live code,
equations, visualizations and narrative text. Uses include: data cleaning and transformation, numerical simulation,
statistical modeling, data visualization, machine learning, and much more.
1. To open a Jupyter notebook, go to the address of the cluster, below [Crane](crane.unl.edu) will be used as an example, sign in using your hcc credentials (NOT your
campus credentials).

2. Select your preferred authentication method.

3. Choose a job profile. Select "Noteboook via SLURM Job | Small (1 core, 4GB RAM, 8 hours)" for light tasks such as debugging or small-scale testing.
Select the other options based on your computing needs. Note that a SLURM Job will save to your "work" directory.

## Running Code
1. Select the "New" dropdown menu and select the file type you want to create.

2. A new tab will open, where you can enter your code. Run your code by selecting the "play" icon.

2. A terminal opens in a new tab. You can enter [Linux commands]({{< relref "basic_linux_commands" >}})
at the prompt.

## Using Custom Packages
Many popular `python` and `R` packages are already installed and available within Jupyter Notebooks.
However, it is possible to install custom packages to be used in notebooks by creating a custom Anaconda
Environment. Detailed information on how to create such an environment can be found at
[Using an Anaconda Environment in a Jupyter Notebook on Crane]({{< relref "/applications/user_software/using_anaconda_package_manager#using-an-anaconda-environment-in-a-jupyter-notebook-on-crane" >}}).
