+# Disk Image Creator
+
+The Disk Image Creator is a tool that uses a simple textual description of a disk image to create actual images.
+
+This tool is incredibly valuable when implementing your own operating system or deployments.
+
+## Example
+
+```plain
+
+```
+
+## Available Content Types
+
+```plain
+
+```
+
+### Empty Content (`empty`)
+
+This type of content does not change its range at all and keeps it empty. No bytes will be emitted.
+
+```plain
+empty
+```
+
+### Fill (`fill`)
+
+The *Fill* type will fill the remaining size in its space with the given `<byte>` value.
+
+```plain
+fill <byte>
+```
+
+### Raw Binary Content (`raw`)
+
+The *Raw* type will include the file at `<path>` verbatim and will error, if not enough space is available.
+
+`<path>` is relative to the current file.
+
+```plain
+raw <path>
+```
+
+### MBR Partition Table (`mbr-part`)
+
+```plain
+
+```
+
+### GPT Partition Table (`gpt-part`)
+
+```plain
+
+```
+
+### FAT File System (`fat`)
+
+```plain
+
+```
