+If the file ~/.ssh/config doesn't exist yet on your local computer, you may need to create the directory ~/.ssh and/or create and edit the file ~/.ssh/config.
+
+On Linux, Mac, and WSL, if you prefer, you can do so using the command line in your terminal window via the following.
+{{{
+cd  # change the current directory to your home directory as needed
+mkdir -p .ssh # create the subdirectory .ssh as needed
+cd .ssh # change to that subdirectory
+nano config # create, as needed, and edit and save the file named config.
+}}}
+For file editing with nano, etc., see [[https://wiki.hpc.tulane.edu/trac/wiki/cypress/FileEditingSoftware/Example|File Editing Example]].
+
+In the case of nano, you can simply copy and paste the contents into the window and save the result.
+
+For Windows terminal, you can open a window for notepad from the command line via the following.
+{{{
+cd &rem change directory to your home directory
+notepad .ssh\config
+}}}
+Note that the hostname included in the file must match the hostname that you used in your **ssh** command.
