+  > This may require forking [the webapp from devolutions-gateway](https://github.com/Devolutions/devolutions-gateway/tree/master/webapp), modifying `webapp/`, building, and specifying a new [static root path](https://github.com/Devolutions/devolutions-gateway/blob/a884cbb8ff313496fb3d4072e67ef75350c40c03/devolutions-gateway/tests/config.rs#L271).

+/**
+ * @file Defines the custom logic for patching in UI changes/behavior into the
+ * base Devolutions Gateway Angular app.
+ *
+ * Defined as a JS file to remove the need to have a separate compilation step.
+ * It is highly recommended that you work on this file from within VS Code so
+ * that you can take advantage of the @ts-check directive and get some type-
+ * checking still.
+ *
+ * Other notes about the weird ways this file is set up:
+ * - A lot of the HTML selectors in this file will look nonstandard. This is
+ *   because they are actually custom Angular components.
+ * - It is strongly advised that you avoid template literals that use the
+ *   placeholder syntax via the dollar sign. The Terraform script looks for
+ *   these characters so that it can inject Coder-specific values, so any
+ *   template literal that uses the character actually needs to double up each
+ *   of them. There are already a few places in this file where it couldn't be
+ *   avoided, but avoiding this as much as possible will save you some headache.
+ * - All the CSS should be written via custom style tags and the !important
+ *   directive (as much as that is a bad idea most of the time). We do not
+ *   control the Angular app, so we have to modify things from afar to ensure
+ *   that as Angular's internal state changes, it doesn't modify its HTML nodes
+ *   in a way that causes our custom styles to get wiped away.
