Abstract: The disclosed technology is generally directed to mixed reality devices. In one example of the technology, an author is enabled to align a guide to a real-world environment. The author is enabled to edit a mixed-reality view for at least one step of the guide. The author is enabled to view the mixed-reality view associated with the step. The mixed-reality view includes the real-world environment and holographic elements. The author is enabled to, within the mixed-reality view, place a holographic instruction card at a location in the real-world environment. The holographic instruction card includes at least one text instruction associated with the step. The author is enabled to, within the mixed-reality view, place a first three-dimensional hologram at another location in the real-world environment. The author is enabled to, within the mixed-reality view, edit at least one visual element of the first three-dimensional hologram.
