• Useful commands in terminal: pwd (returns current directory), ls (see what files are present in current directory), cd (change directory)
• To create environment: use steps outlined in the environment set-up provided above (conda env create -f environment.yml). To edit environment: edit the environment file created, but substitute "create" for "update" in line typed into the terminal (conda env update -f environment.yml)
• TO COPY/PASTE IN TERMINAL, SHIFT + SELECT

GIT INFORMATION

• Git is designed to save relative changes between text files and allows you to see distinct points across a history of changes through "commits"
• Git is folder based: can branch off to develop a certain aspect of code, work on it independently from the main branch, then merge changes between them
• General workflow: commit changes after relevant progress points, push changes daily
• Useful commands: git status to see the status of various files, git add to add a file to the "changes to be committed" heading, git commit -m "Notes" to commit changes (pay attention to symbols, quotes, and apostrophes in notes), git push to push changes
• Revision commands: git log to see file hashes, git checkout to see either hashes or go back to main
• To pull changes from GitHub: git pull then Ctr+c then :q +enter, should change everything okay

@andrewfagerheim - We should read this paper: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL100450 They are talking very specifically about the Arctic, but based on a quick skim it seemed very relevant to your proposal.
