+# Chapter 5 notes and practice
+## Git version control 
+- Can rollback code to a time when things worked if something stops working
+- Good for reproducibility
+- Tracks changes and makes it easy for others to access those changes
+- Makes things available to others after people move on from projects
+
+## Basic Git
+- Telling git who you are: I've already done this. Is it possible to add a different email? I have used my personal email in the past rather than the ISU email
+- My color ui is already set to true
+- I made a respository on github (it was empty) and cloned it to hpc-class
+
+### 'git status' shows you status of repository 
+- I have an untracked file right now
+
+### 'git add' adds that file if you specify the file name
+
+I have a test file to be committed now (it's staged)
+
+### The snapshot: git commit 
+'git commit' -m "initial test import"' is how i committed this 
+- git commit takes a snapshot, essentially
+
+### 'git diff' shows you shows you differences in working directory vs what's been staged
+
+### 'git log' shows your chain of commits
+- This can get pretty long (as it did with Wade's work)
+- In that case you may need to ctl-c out of it
+
+### A couple other commands
+1. 'git rm <filename>' removes files
+2. 'git mv ' moves them and can be used to change extension
+
+### '.gitignore' file tells you what to ignore
+- I made a file "ignoreme.txt" in a "junk" folder and told git to ignore it
+- Useful for ignoring big files, intermediate files, and temp files
+
+### 'git reset' lets you undo things you've staged (removes them from staging)
+- ex I added a line "messy addition" to my readme and then removed it
+
+## At this point I pushed these to my [practice repository](https://github.com/ekmcmurchie/EEOB_546_McMurchie) (click link to view) and then switched on over to doing this exercise
