+# Day 8
+
+Today we will learn to move around different branches.
+
+## Problem Statement:
+One of your colleagues messed up here, and put the branches in the wrong timelines!<br>
+You could delete and re-create these branches - but you can also directly move them to different commits, by using:
+```bash
+git checkout
+```
+
+on the branch names, and then using:
+```bash
+git reset --hard
+```
+
+on the commit where you want the branch to be.
+
+The donut branch is in the right place, but the timeline is still incomplete - make you actually *eat* the donut in that branch!
+
+### Questions:
+ - Did you eat a baguette on the baguette branch?
+ - Did you drink a coffee on the coffee branch?
+ - Did you eat a donut on the donut branch?

+
+## Solution
+
+1. Checkout all the different branches and the file.
+```bash
+git checkout baguette
+git checkout coffee
+git checkout donut
+
+# Check the file
+nvim you.txt
+```
+
+2. After checking the file, reset or delete the branch.
+```bash
+git branch -D baguette
+git branch -D coffee
+```
+
+3. Then go the respective position on where the actual branch should be there.
+```bash
+git checkout SHA Code
+
+# Then create the branch that is required.
+git branch baguette
+
+# Again for branch - coffee
+git checkout SHA Code
+git branch coffee
+```
+
+4. Go to the donut branch and make the changes.
+```bash
+git checkout donut
+
+# Make the changes and commit
+git add .
+git commit -m "ate donut"
+git push -u origin main
+```
