++ Auto detect and create entries for .iso files in /iso/

++ Small and lean, few entries lots of images

+If your pendrive is already formated to FAT, you only need to change its label
+to GIM and then skip step `1`. To use different name changes to the scripts are
+required, more on this later (step `3`).

-3. Add isos to /boot/iso/
--------------------------
+## 3. Adjusts
+
+### 3.1 I don't want to change the label
+
+If you didn't change your label to `GIM` you will need to change
+`/tmp/GIM/boot/grub/grub.cfg` last line:
+
+```diff
+-scan_isos /boot/iso GIM
++scan_isos /boot/iso <label>
+```
+
+### 3.2 I want my GRUB to look like that
+
+Find a [theme](https://www.gnome-look.org/browse/cat/109/ord/rating/) you would
+like to use. The one from the screenshot above is
+[vimix](https://www.gnome-look.org/p/1009236/#files-panel).
+
+Move the theme contents to the `themes` folder of the instalation, like so:
+
+```
+mount /dev/disk/by-label/GIM /tmp/GIM
+tar xvf Vimix-1080p.tar.xz -C /tmp/
+mv /tmp/Vimix-1080p/Vimix /tmp/GIM/boot/grub/themes/vimix
+```
+
+Double check that you have the `theme.txt` file in the correct place
+`/tmp/GIM/boot/grub/themes/vimix/theme.txt`.
+
+As the last step, select the theme in `/tmp/GIM/boot/grub/grub.cfg`:
+
+```diff
+-  set theme=/boot/grub/themes/starfield/theme.txt
++  set theme=/boot/grub/themes/vimix/theme.txt
+scan_isos /boot/iso GIM
+```
+
+release the pendrive.
+
+```
+umount /tmp/GIM
+```
+
+## 4. Add isos to /boot/iso/
+
+Menu entries will be populated according to the files present during boot.
+To add isos via terminal, just copy them over:
+
+```
+mount /dev/disk/by-label/GIM /tmp/GIM
+cp <my-iso-file>.iso /tmp/GIM/boot/iso/
+umount /tmp/GIM
+```
