+## Git Borg Linker - checkout {.unnumbered .unlisted}
+
+
+Let's go back to our example project (in slide 11, 14, 15 and 17):
+
+In this project, we're using *hooks*:
+
+```bash
+$ echo "echo 'a newline' >> results/result.txt" >> src/script.sh # Add anew line into result.txt file
+$ bash src/script.sh # Execute the script
+$ cat results/result.txt # display the new content of the file
+result line
+a newline
+
+$ git add src/script.sh && git commit -m "src/script.sh: update"
+...
+
+$ git co df0eb55ce43fa48b652340183b5f9cc69daa2350 # checkout to the first commit, gblk checkout is executed after that command
+...
+HEAD est maintenant sur df0eb55 src/script.sh: initial commit
+
+$ cat results/result.txt
+result line
+
+$ git co master
+Basculement sur la branche 'master'
+
+$ cat results/result.txt
+result line
+a newline
+```
+
+
+## Git Borg Linker - checkout {.unnumbered .unlisted}
+
+
+Example with unsaved results in our results folder:
+
+```bash
+$ echo "test" >> results/result.txt
+$ echo "new files" > results/new.txt
+$ git co df0eb55ce43fa48b652340183b5f9cc69daa2350
+    +27 B     -22 B results/result.txt
+added          10 B results/new.txt
+
+Your results folder contains unsaved changes!
+Please update your current commit with:  gblk commit --update
+Or revert it back to it's previous state with gblk commit --revert
+```
+
+Usaved changes are detected, you can:
+
+  - discard unsaved changes with `gblk commit --revert`
+  - update the current archive with the new content inside the results folder with `gblk commit --update`
