+# Installation
+This app is based off of the [create-landscape-app](https://github.com/urbit/create-landscape-app) scaffolding.
+
+To install, first boot your ship, and mount its pier using `|mount %` in the Dojo.
+
+Then clone this repo, and create  a file called `.urbitrc` at the root of the repo directory
+with the following contents:
+
+```
+module.exports = {
+  URBIT_PIERS: [
+    "/path/to/ship/home",
+  ]
+};
+```
+
+For instance, if the repo was cloned into the same directory as a planet with a pier
+`zod`, you might make the path `../zod/home`.
+
+Then run the following Unix commands from the root of the repo:
+```
+$ yarn
+$ yarn run build
+```
+
+This will build and package the javascript files, and move them into the directory
+specified in the `.urbitrc` file.
+
+Finally, run `|commit %home` in your ship's Dojo to make Urbit aware of those files,
+and then run `|start %barttile` to start the app. You should then see a `BART info`
+tile on your Landscape home screen.
