+### Importing the project into Eclipse
+
+Elasticsearch builds using Gradle and Java 13. When importing into Eclipse you
+will either need to use an appropriate JDK to run Eclipse itself (e.g. by
+specifying the VM in [eclipse.ini](https://wiki.eclipse.org/Eclipse.ini) or by
+defining the JDK Gradle uses by setting **Prefercences** > **Gradle** >
+**Advanced Options** > **Java home** to an appropriate version.
+
+IMPORTANT: If you have previously imported the project by running `./gradlew eclipse`
+           then you must build an entirely new workspace and `git clean -xdf` to
+           blow away *everything* that the gradle eclipse plugin made.
+
+ - Select **File > Import...**
+ - Select **Existing Gradle Project**
+ - Select **Next** then **Next** again
+ - Set the **Project root directory** to the root of your elasticsearch clone
+ - Click **Finish**
+
+This will spin for a long, long time but you'll see many errors about circular
+dependencies. Fix them:
+
+ - Select **Window > Preferences**
+ - Select **Java > Compiler > Building**
+ - Look under **Build Path Problems**
+ - Set **Circular dependencies** to **Warning**
+ - Apply that and let the build spin away for a while
+
+Next you'll want to import our auto-formatter:
+
+ - Select **Window > Preferences**
+ - Select **Java > Code Style > Formater**
+ - Click **Import**
+ - Import the file at **buildSrc/formatterConfig.xml**
+ - Make sure it is the **Active profile**
+
+Finally, set up import order:
+
+ - Select **Window > Preferences**
+ - Select **Java > Code Style > Organize Imports**
+ - Click **Import...**
+ - Import the file at **buildSrc/elastic.importorder**
+ - Set the **Number of imports needed for `.*`** to ***9999***
+ - Set the **Number of static imports needed for `.*`** to ***9999*** as well
+ - Apply that
+
+IMPORTANT: There is an option in **Gradle** for **Automatic Project Synchronization**.
+           As convenient as it'd be for the projects to always be perfect this
+           tends to add many many seconds to every branch change. Instead, you
+           should manually right click on a project and
+           **Gradle > Refresh Gradle Project** if the configuration is out of
+           date.
+
+As we add more subprojects you might have to re-import the gradle project (the
+first step) again. There is no need to blow away the existing projects before
+doing that.
