+    The &lt;code>JDT Core&lt;/code> configuration provisions a dedicated development environment for the complete set of projects that comprise the JDT Core,
+    i.e. the projects that are contained in the &lt;a href=&quot;https://github.com/eclipse-jdt/jdt.core&quot;>jdt.core&lt;/a> repository.
+    &lt;/p>
+    &lt;p>
+    The installation is based on the latest successful integration build of the &lt;code>Eclipse Platform SDK&lt;/code>,
+    the PDE target platform, like the installation, is also based on the latest integration build,
+    and the API baseline is based on the most recent release.
+    &lt;p>
+    &lt;/p>
+    Please &lt;a href=&quot;https://wiki.eclipse.org/Eclipse_Platform_SDK_Provisioning&quot;>read the tutorial instructions&lt;/a> for more details.
