-## Using a custom GeckoView

-Create a file called `user.properties` in the top-level project directory. Add a variable called `geckoViewLocalArm` and `geckoViewLocalX86` and set it to the location of your locally built AAR:
+### Dependency substitutions
+
+You might be interested in building this project against local versions of some of the dependencies.
+This could be done either by using a [local maven repository](https://mozilla-mobile.github.io/android-components/contributing/testing-components-inside-app) (quite cumbersome), or via Gradle's [dependency substitutions](https://docs.gradle.org/current/userguide/customizing_dependency_resolution_behavior.html) (not at all cumbersome!).
+
+Currently, the substitution flow is streamlined for some of the core dependencies via configuration flags in `local.properties`. You can build against a local checkout of the following dependencies by specifying their local paths:
+- [GeckoView](https://hg.mozilla.org/mozilla-central), specifying its path via `dependencySubstitutions.geckoviewTopsrcdir=/path/to/mozilla-central` (and, optionally, `dependencySubstitutions.geckoviewTopobjdir=/path/to/topobjdir`). See [Bug 1533465](https://bugzilla.mozilla.org/show_bug.cgi?id=1533465).
+  - This assumes that you have built, packaged, and published your local GeckoView -- but don't worry, the dependency substitution script has the latest instructions for doing that.
+
+Do not forget to run a Gradle sync in Android Studio after changing `local.properties`. If you specified any substitutions, they will be reflected in the modules list, and you'll be able to modify them from a single Android Studio window.
