The variable's information in Hob should probably resemble the descriptions in the manual's Glossary. So for "Image basic size" it should say something like: "Defines the size for the generated image. The OpenEmbedded build system determines the final size for the generated image using an algorithm that takes into account the initial disk space used for the generated image, the Image basic size value, and the Additional free space value. For more information, check the Yocto Project Reference Manual" The words "Yocto Project Reference Manual" are a link to: http://www.yoctoproject.org/docs/current/poky-ref-manual/poky-ref-manual.html#var-IMAGE_ROOTFS_SIZE
