+If your Eclipse IDE doesn't already have the `net.sf.j2s.core.jar` plugin, you can run on CLI
+```
+gradle jalviewjsEclipseCopyDropins -Pjalviewjs_eclipse_root=/Applications
+```
+(replacing `/Applications` with the folder where your IDE Eclipse is installed).
+You should also only need to do this once but you will have to restart Eclipse if it was already running.
+
+## Building site
+
+The important gradle tasks needed to build and test the site have been adapted/duplicated into the _jalview in eclipse_ group of tasks which you can find in the _Gradle Tasks_ window/tab.
+
+To build the site, your Eclipse should be creating the transpilation continuously into `build/jalviewjs/tmp/site`. If there are no transpiled files then you should Refresh, Gradle->Refresh Gradle Project, and if nothing has appeared you can Project->Clean which should trigger a rebuild.
+
+You can clean the transpiled code with the gradle task `cleanJalviewjsIDESite`.
+
+To then create the site from the transpiled code and supporting libraries, run the gradle task `jalviewjsIDEBuildSite` which will create a working (hopefully) site in `build/jalviewjs/site`
+
+You can test the build right here in Eclipse, or in a browser of your choice, by running the `jalviewjsIDEServer` task (which is really just the `jalviewjsServer` task). That will start a localhost server and create an access HTML file, `jalviewjsTest.html`.
