 - `Pages`: the default page, shows a list of existing pages - clicking one enables editing that page; a button is also presented for adding a new page. Each `Adapter` will provide different formatting help and can allow editable slugs/URLs or not (eg, the `EurekaAdapter` builds slugs/URLs directly from the page title).
 - `Files`: provides an interface for managing statically hosted files. Files and directories can be added, moved, and deleted.
-- `Build`: a simple form to build the site - build options configurable by `Adapter` are present under an accordion.
 - `Configuration`: interface to the configuration for the `Adapter`. Each `Adapter` provides its own configuration interface with associated data types (currently supported: `int`, `float`, `string`, and `multilinestring`)

 - `DeletePage(slug string) error`: given a slug, delete the corresponding page source and possibly its generated HTML, depending on the `Adapter`
 - `Build(buildOptions map[string][]string) BuildStatus`: takes a map of build option names to their values and builds the site, returning a `BuildStatus` object containing the success or failure as a boolean and the detailed status (eg, the console ouptut of the build process)
+- `Deploy() DeployStatus`: executes the deployment script and returns a `DeployStatus` object, analagous to a `BuildStatus`
