 # Buttons
 
->  Use Bootstrap’s custom button styles for actions in forms, dialogs, and more.
+>  Use Bootstrap’s custom `b-button` component for actions in forms, dialogs, and more.
    Includes support for a handful of contextual variations, sizes, states, and more.
+
+The `b-buton` component generally renders a `<button>` element. However, you can also
+render a an `<a>` element by proding an `href` prop vale. You man also generate
+`vue-router` `<router-link>` when providing a value for the `to` prop (`vue-router`
+is  required).
+
+### Button Sizes
+Fancy larger or smaller buttons? Specify `lg` or `sm` via the `size` prop.
+
+Create block level buttons — those that span the full width of a parent — by
+setting the `block` prop.
+
+### Button contextual variants
+Use the `variant` prop to generate the various bootstrap contextual button variants.
+
+By default `b-button` will render with the `secondary` variant.
+
+#### Solid color variants:
+`primary`, `secondary`, `success`, `warning`, and `danger`.
+
+#### Outline color variants:
+In need of a button, but not the hefty background colors they bring? Use the 
+`outline-*` variants to remove all background images and colors on any `b-button`
+
+`outline-primary`, `outline-secondary`, `outline-success`, `outline-warning`,
+and `outline-danger`.
+
+#### Link variant:
+Variant `link` will reder a button with the appearance of a link while maintaning the
+default passing and size of a button.
+
+### Disabled state
+Set the `disabled` prop to disable button default funtionality. `disabled` also 
+works with buttons rednered as `<a>` elements and `router-link`
+
+### Button type
+When neither `href` nor `to` props are provided, `b-button` renders an html `<button>`
+element.  You cn specify the button's type by setting the prop `type` to `button`,
+`submit` or `reset`.  The default type is `button`.
+
+### Router links
+Refer to [`vue-router`](https://router.vuejs.org/) docs for the various router-link related props.
+
+Note the `tag`attribute for `router-link` is refered to as `router-tag` in `bootstrap-vue`
+
+### Alias
+`<b-button>` can also be used by its shorter alias `<b-btn>`

-# Forms Checkbox
+# Form Checkbox Input
 
+> For cross browser consistency, `b-form-checkbox` uses Bottstrap's custom
+checkbox input to replace the browser default checkbox input. It is built on top of
+semantic and accessible markup, so it is a solid replacement for the default checkbox input.
+
+### Value
+By default, the checkbox value will be `true` when checked and `false` when unchecked.
+You can customize the checked and unchecked values by specifying the `value` and `unchecked-value`
+properties.
+
+`v-model` binds to the `checked` property.  When you have multiple checkboxes that bind to a
+single data state variable, provide an array reference `[]` to your `v-model`.
+
+### Control sizing
+Set heights using thw `size` prop to `sm` or `lg` for small or large respectively.
+
+### Non custom check inputs
+You can have `b-form-checkbox` render a browser native chechbox input by setting the `plain` prop.

-# Form fieldsets
+# Form fieldset (Form group)
 
+> The `b-form=fieldset` component is the easiest way to add some structure to forms. Its
+purpose is to provide a label and control pairing, help text and feedback text, as well
+as contextual state visual feedback
+
+### Options
+
+#### Label:
+The content of the generted `<label>` element (html supported).
+You may optionally visually hide the label by setting the prop `label-sr-only`.
+
+By default, the label apepars above the input element, but you may optionallu set
+the prop `horizontal` to place the label on the same line and control the width
+of the label by setting `label-size` to the number of columns (default of `3`).
+`label-size` has no effect if the layout is not `horizontal`
+
+The label may also optionally be alligned `left`, `center` or `right` by setting
+the respective value via the prop `label-text-align`. Alignment has no effect if
+`label-sr-only` is set.
+
+#### Description:
+Optional descriptive text which is always shown with the `.text-muted` class (html supported).
+
+#### Feedback:
+Optional text to provide textual state feedback (html supported).
+
+#### Contextual visual state:
+Optional contextual visual feedback state of `danger`, `warning` or `success`.
+You should always provide `feedback` content to assit users using assistive technologies.
+
+### Accessibility
+To enable auto-generateion of `aria-*` attributes, you must supply a unique `id`
+prop to `b-form-fieldset`.
+
+To automatically associate the label to the first input element, you must provide
+a unique `id` prop on the input component. You may optionally specify which containing
+input component the label is for by setting the `b-form-fieldset` prop `for` to the
+id string of the input.
+
+It is highly recommended that you provide a unique `id` prop on your input element.

+### Contextual States
+Bootstrap includes validation styles for danger, warning, and success states on most form controls.
+
+Generally speaking, you’ll want to use a particular state for specific types of feedback:
+- `danger` is great for when there’s a blocking or required field. A user must fill in
+this field properly to submit the form.
+- `warning` works well for input values that are in progress, like password strength, or
+soft validation before a user attempts to submit a form.
+- `success` is ideal for situations when you have per-field validation throughout a form

+Using these contextual states to denote the state of a form control only provides
+a visual, color-based indication, which will not be conveyed to users of assistive
+technologies - such as screen readers - or to colorblind users.
+
+Ensure that an alternative indication of state is also provided. For instance, you
+could include a hint about state in the form control's `<label>` text itself, or by
+providing an additional help text block. Specifically for assistive technologies, 
+invalid form controls can also be assigned an `aria-invalid="true"` attribute.
