+```
+
+and then import it on your arm machine.
+```bash
+docker load --input comic-dl.tar
+```
+
+and then use the correct alias:
+
+```bash
+alias comic_dl="docker run -it --rm -v $(pwd):/directory -w /directory comic-dl:py3.8-buster-armv7 comic_dl -dd /directory"
+```

 ## Python Support
 This script supports python 3. You can run this on python 2 as well, as long as you have all the dependencies installed.
