 ### property editable
 
+This is a boolean property that determines whether the form can be edited. If `editable` is false, the form is view-only; if `editable` is true, the form becomes editable.
+
+```javascript
+myForm.editable = true; // make form editable
+myForm.editable = false; // make form view-only and update the model
+```
+
 ### property model
 
+This property holds the data model used to populate the form. It should in most cases be an object.
+
+```javascript
+let record = { id: 42, type: "note", description: "This is a note." };
+myForm.model = record;
+```
+
 ### property layout
 
+Access the `FormLayout` of the form.
+
+### dom() → Element
+
+Get the DOM of the form. This can be passed to a new dialog as the body, or appended to an element on the webpage.
+
+```javascript
+const formContainer = document.querySelector('#formcontainer');
+formContainer.appendChild(myForm.dom());
+```
+
 ## class FormLayout
 
 This class can not be created, only accessed via `JsonForm.layout`.
 
+### addRow() → FormRow
+
+```javascript
+let newRow = myForm.layout.addRow();
+```
+
 ## class FormRow
 
 This class can not be created directly, only via `FormLayout.addRow()`.
 
+### append(field) → self
+
+```javascript
+let newRow = myForm.layout.addRow();
+newRow.append(new TextField({ label:"Description", path:".description" }));
+```
+
 ## class Field
 
+Common field options:
+
+- **label** - string: the field label
+- **path** - string: the JSON path in the model for this field
+- **locked** - bool: make field read-only
+- **nullable** - bool: assume null for this value if the field is empty
+
 ## class TextField
 
 ## class NumberField
 
+- **fixed** - int: save the number as a string, with *n* decimals.
+- **float** - bool: save the number as a float, unrounded.
+
+Note: If neither **fixed** or **float** is set, the value will be saved as an integer.
