     6. Run `./gradlew publishToMavenLocal`.
 
 3. Inside the `fenix` repository root:
-    1. Inside [`build.gradle`][fenix-build-gradle-1], add
-       `mavenLocal()` inside `allprojects { repositories { <here> } }`.
+    1. Inside [`build.gradle`][fenix-build-gradle] you need to add `mavenLocal()` twice.  
+       First add `mavenLocal()` inside `buildscript` like this:
+       ```
+       buildscript {
+           repositories {
+               mavenLocal()
+               ...
+       ```
 
-    2. Inside [`buildSrc/src/main/java/Dependencies.kt`][fenix-deps], change
-       `mozilla_android_components` to the version you defined in step 3 part 1.
+       Second add `mavenLocal()` inside `allprojects`:
+       ```
+       allprojects {
+           repositories {
+               mavenLocal()
+               ...
+       ```
 
-       Example: `const val mozilla_android_components = "24.0.0-TESTING1"`
+    2. Inside [`buildSrc/src/main/java/AndroidComponents.kt`][fenix-deps], change
+       `VERSION` to the version you defined in step 3 part 1.
 
-       In the same file change `mozilla_glean` to the version you defined in step 1 part 1.
-
-       Example: `const val mozilla_glean = "22.0.0-TESTING1"`
-
-    3. Change the `Versions.mozilla_android_components.endsWith('-SNAPSHOT')` line in [`app/build.gradle`](https://github.com/mozilla-mobile/fenix/blob/1f250a730d4f1bbd42bc15079eb98d1b01a34cf0/app/build.gradle#L628) to `Versions.mozilla_android_components.endsWith('-TESTING$N')` where `$N` is the number to reference the version you published in part 2.
+       Example:
+       ```
+       const val VERSION = "24.0.0-TESTING1"
+       ```
 
 You should now be able to build and run Fenix (assuming you could before all this).
