1. Open https://www.anaconda.com/products/individual#download-section with your web browser.
2. Download the Anaconda Installer with Python 3 for Linux.
   (The installation requires using the shell. If you aren't comfortable doing the installation yourself stop here and request help at the workshop.)
3. Open a terminal window and navigate to the directory where the executable is downloaded (e.g., `cd ~/Downloads`).
4. Type

   bash Anaconda3-

   and then press Tab to autocomplete the full file name. The name of file you just downloaded should appear.
5. Press Enter (or Return depending on your keyboard). You will follow the text-only prompts. To move through the text, press Spacebar. Type yes and press enter to approve the license. Press Enter (or Return) to approve the default location for the files. Type yes and press Enter (or Return) to prepend Anaconda to your PATH (this makes the Anaconda distribution the default Python).
6. Close the terminal window.

1. Download the Git for Windows installer.
2. Run the installer and follow the steps below:

   Git 2.27.0 Setup

   1. Click on "Next" four times (two times if you've previously installed Git). You don't need to change anything in the Information, location, components, and start menu screens.
   2. From the dropdown menu select "Use the nano editor by default" and click on "Next".

   Adjusting your PATH environment

   3. Ensure that "Git from the command line and also from 3rd-party software" is selected and click on "Next". (If you don't do this Git Bash will not work properly, requiring you to remove the Git Bash installation, re-run the installer and to select the "Git from the command line and also from 3rd-party software" option.)

   Choosing the SSH executable

   Choosing HTTPS transport backend

   4. Ensure that "Use the native Windows Secure Channel library" is selected and click on "Next".

   This should mean that people stuck behind corporate firewalls that do MITM attacks with their own root CA are still able to access remote git repos.

   Configuring the line ending conversions

   5. Ensure that "Checkout Windows-style, commit Unix-style line endings" is selected and click on "Next".

   Configuring the terminal emulator to use with Git Bash

   6. Ensure that "Use Windows' default console window" is selected and click on "Next".

   Configuring extra options

   7. Ensure that "Default (fast-forward or merge) is selected and click "Next"
   8. Ensure that "Enable file system caching" and "Enable Git Credential Manager" are selected and click on "Next".

   Configuring experimental options

   9. Click on "Install".

   Installing

   Completing the Git Setup Wizard

   as of 2020-06-02, the Window will say "click Finish", but the button is labelled as "Next"

   10. Click on "Finish" or "Next".
3. If your "HOME" environment variable is not set (or you don't know what this is):
   1. Open command prompt (Open Start Menu then type cmd and press Enter)
   2. Type the following line into the command prompt window exactly as shown:

      setx HOME "%USERPROFILE%"

   3. Press Enter, you should see SUCCESS: Specified value was saved.
   4. Quit command prompt by typing exit then pressing Enter

This will provide you with both Git and Bash in the Git Bash program.

Video Tutorial: Windows Installation

The default shell in some versions of macOS is Bash, and Bash is available in all versions, so no need to install anything. You access Bash from the Terminal (found in /Applications/Utilities). See the Git installation video tutorial for an example on how to open the Terminal. You may want to keep Terminal in your dock for this workshop.

To see if your default shell is Bash type echo $SHELL in Terminal and press the Return key. If the message printed does not end with '/bash' then your default is something else and you can run Bash by typing bash

If you want to change your default shell, see this Apple Support article and follow the instructions on "How to change your default shell".

The default shell is usually Bash and there is usually no need to install anything.

To see if your default shell is Bash type echo $SHELL in a terminal and press the Enter key. If the message printed does not end with '/bash' then your default is something else and you can run Bash by typing bash.

Git should be installed on your computer as part of your Bash install (see the Shell installation instructions).

For macOS, install Git for Mac by downloading and running the most recent "mavericks" installer from this list. Because this installer is not signed by the developer, you may have to right click (control click) on the .pkg file, click Open, and click Open on the pop up window. After installing Git, there will not be anything in your /Applications folder, as Git is a command line program. For older versions of OS X (10.5-10.8) use the most recent available installer labelled "snow-leopard" available here.

If Git is not already available on your machine you can try to install it via your distro's package manager. For Debian/Ubuntu run sudo apt-get install git and for Fedora run sudo dnf install git.
