 ## about
 
-`onyx/scry` is a lightweight map annotation and location data management and sharing tool built using [leaflet](https://leafletjs.com) and [typescript](https://typescriptlang.org). It is intended as a standalone tool to generate, manage, and share simple location data in the form of points, circles, and polygons. All of these have associated titles and descriptions and can be easily imported or exported to a `json` format for easy sharing. All data is saved locally via the `localStorage` API, and the only network calls are those to retrieve either the streetmap or satellite tile data.

 ## usage
 
-_coming soon_
+When you launch the application for the first time, it will ask for your current location to set the `home` point. If you deny permission or it can't determinte your location, you can set it later via the menu and the map will zoom out to fit the entire Earth.
+
+Along the bottom is the control bar, containing the following buttons:
+
+- `Home`: If the `home` point has been set, center the map view on it.
+- `Marker`: Enter marker creation mode.
+- `Circle`: Enter circle creation mode.
+- `Polygon`: Enter polygon creation mode.
+- `Tileset`: Swap the map tiles between the streetmap and satellite imagery.
+- `Save`: Saves your current overlays to local storage.
+- `Clear`: Clears all overlays from the map.
+- `Restore`: Restores overlays from local storage.
+- `Menu`: Show/hide the overlay management menu.
+
+Clicking an overlay shows a popup with the name and description.
+
+### Overlay Creation
+
+Clicking the `Marker`, `Circle`, or `Polygon` buttons, you enter overlay creation mode for that overlay type. A small window at the bottom of the screen appears with a cancel button which allows you to leave this mode.
+
+For Markers and Circles, you just click anywhere on the map to bring up the Overlay Creation window.
+
+For Polygons, you click points on the map to add them to the polygon — you will see the outline once you have added at least two points. Once you have added at least three points, an OK button appears on the window at bottom, and clicking it opens the Overlay Creation window.
+
+In the Overlay Creation window, you can set a name and optionally a description for the overlay. For circles, you also set the radius in meters, which defaults to 500. Pressing the `OK` button saves the overlay to the map.
+
+### Overlay Management
+
+Opening the menu shows a list of all overlays organized by type; clicking on any overlay brings up the `Overlay Detail` window. At the bottom of the menu are also three buttons:
+
+- `Set Home`: Sets the `home` point to the center of the current map view.
+- `Import`: Opens the Import window to import overlay data from JSON format.
+- `Export All`: Opens the Export window to export all overlay data to JSON format.
+
+### Overlay Detail
+
+This window is similar to the Overlay Creation window save the addition of three buttons:
+
+- `Go Here`: Centers the map view on this overlay.
+- `Export`: Opens the Export window to export this overlay to JSON format.
+- `Delete`: Deletes this overlay from the map.
+
+### Import/Export
+
+When exporting, the `Copy to Clipboard` button does just that. The JSON data can then be saved to a text file, emailed to a friend, or what have you.
+
+When importing, the imported data is added to the current overlays. If you want to overwrite your current data, clear it first.
+
+## build/deploy
+
+If you want to hack on `onyx-scry` and rebuild it, I recommend rebuilding the `sourcemapper` (written in `go`) in the `buildtools` directory first (in case your `glibc` version is older).
+
+The build process for `onyx-scry` is a bit unorthodox. Instead of using modules, the `typescript` code is all concatenated before transpiling. The `sourcemapper` is used to show lines in the original source where transpilation errors occured, in a plumbable address format so you can right-click in `acme` and go directly to that line of code.
+
+From the `src` directory, you can just run `./build.sh`. Once built, the final `javascript` file is located in the `static` directory with the rest of the application.
+
+Deploying is simple: just serve the `static` directory.
