+This guide explains how to increase the disk size of a Lima VM running on macOS when you've run out of space, as well as how to edit the disk size using the `limactl` CLI.
+
+## Resize Disk Using limactl
+
+Starting with v1.1, Lima supports editing the disk size of an existing instance using the `--disk` flag with the `limactl edit` command.  
+This is the recommended and simplest way to resize your VM disk.
+
+```sh
+limactl edit <vm-name> --disk <new-size>
+```
+
+Example for 20GB:
+
+```sh
+limactl edit default --disk 20
+```
+
+> **Note:**  
+> - Increasing disk size is supported, but shrinking disks is not recommended.
+> - The instance may need to be stopped before editing disk size.
