+In this example we kill the process (with Ctrl + C) after 3 checkpoints (at 0,
+100, and 200). The <abbr>cache</abbr> will contain those 3 versions of
+`int.txt`. And DVC applies the last checkpoint to the <abbr>workspace</abbr>
+even when more cycles happened before the interrupt:
+
+```dvc
+$ cat int.txt
+200
+$ ls .dvc/cache
+36  cf  f8
+```
+
+`dvc exp show` will display these checkpoints as an experiment branch:
+
+```dvc
+$ dvc exp show

+Now if we use `dvc exp run` again, the process will start from 200. To restart
+from a previous point or even from scratch, you can use use `dvc exp apply`.
