 * Avoid using the ternary operator except for trivial expressions.
 * Use an assertion from Airlift's `Assertions` class if there is one that covers your case rather than writing the assertion by hand. Over time we may move over to more fluent assertions like AssertJ.
 * When writing a Git commit message, follow these [guidelines](https://chris.beams.io/posts/git-commit/).

+## Building the Web UI
+
+The Presto Web UI is composed of several React components and is written in JSX and ES6. This source code is compiled and packaged into browser-compatible Javascript, which is then checked in to the Presto source code (in the `dist` folder). You must have [Node.js](https://nodejs.org/en/download/) and [Yarn](https://yarnpkg.com/en/) installed to execute these commands. To update this folder after making changes, simply run:
+
+    yarn --cwd presto-main/src/main/resources/webapp/src install
+
+If no Javascript dependencies have changed (i.e., no changes to `package.json`), it is faster to run:
+
+    yarn --cwd presto-main/src/main/resources/webapp/src run package
+
+To simplify iteration, you can also run in `watch` mode, which automatically re-compiles when changes to source files are detected:
+
+    yarn --cwd presto-main/src/main/resources/webapp/src run watch
+
+To iterate quickly, simply re-build the project in IntelliJ after packaging is complete. Project resources will be hot-reloaded and changes are reflected on browser refresh.
