 ## Metadata
 
-Model-viewer configurations and annotations can be added as a json string in the file's description.
+Model-viewer configurations and annotations can be added as TOML in the file's description.
 
 ### Viewer Configuration
 
-Configuration of the model-viewer instance is contained in the `viewerConfig` object.
+Configuration of the model-viewer instance is contained in the `[viewerConfig]` object.
 This object can contain any number of child objects each of which describes a different possible configuration.
 Each configuration can have properties matching the any of the attributes of the model-viewer element except for `src`, `class`, `interpolation-delay`, and `interaction-prompt`.
+If adding a poster image, the value of the `poster` property must be the name of an image in the Wiki's File namespace (without the namespace header, e.g., `"My poster.jpg"`).
 
 ### Annotations
 
-Annotations can be configured using the `annotations` object.
+Annotations can be configured using the `[annotations]` object.
 This object can contain any number of child objects each of which describes a different possible annotation.
-The label for each annotation is the name of the child object. Each object has two required properties and two optional properties.
+The label for each annotation is the name of the child object (`[annotations."Label here"]`). Each object has two required properties and three optional properties.
 
 | Property | Required | Description | Example |
 |----------|----------|-------------|---------|
-| `data-position`   | Yes      | String containing the X, Y, and Z coordinates of the annotation. | "0.02297m -0.02544m 0.01780m" |
-| `data-normal`     | Yes      | String containing the X, Y, and Z coordinates of the normal vector of the annotation. | "0.78966m -0.53116m 0.30709m" |
-| `data-orbit`      | No       | String containing the orbit vector of the camera to view annotation. | "2.31rad 2.01rad 0.65m" |
-| `data-target`     | No       | String containing the X, Y, and Z coordinates of the camera target to view annotation. | "-0.01029m 0.00071m 0.01138m" |
+| **data-position**   | Yes      | String containing the X, Y, and Z coordinates of the annotation. | "0.02297m -0.02544m 0.01780m" |
+| **data-normal**     | Yes      | String containing the X, Y, and Z coordinates of the normal vector of the annotation. | "0.78966m -0.53116m 0.30709m" |
+| **data-orbit**      | No       | String containing the orbit vector of the camera to view annotation. | "2.31rad 2.01rad 0.65m" |
+| **data-target**     | No       | String containing the X, Y, and Z coordinates of the camera target to view annotation. | "-0.01029m 0.00071m 0.01138m" |
+| **field-of-view**   | No       | String containing the angle of the field of view in degrees. | "35.25deg" |
 
 ### Annotation sets
 
 Annotations sets are specific subsets of the listed annotations that can be shown on the model.
-They are configured using the `annotationSets` object.
-This object can contain any number of child objects each of which contains an array of strings matching the names of the annotation to be included.
+They are configured using the `[annotationSets]` object.
+This object can contain any number properties each of which contains an array of strings matching the names of the annotation to be included.
+The property name is used as the annotation set identifier.
 By default, all annotations are rendered on a model.
+
+## Linking
+
+When adding the model file to a page, use the standard `[[File:Model name.glb]]` internal file link.
+The link supports three optional properties.
+
+| Property | Description | Default |
+|----------|-------------|---------|
+| **view**      | Use one of the non-default configurations specified in the `[viewerConfig]` object. | default viewer configuration |
+| **set**       | Display only the annotations listed in the specified annotation set from the `[annotationSets]` object. | show all annotations |
+| **transform** | Reorder the displayed annotations. Can be either *rand* or *alpha*. | annotations are numbered in the order they are listed in the `[annotations]` object |
