+            In the previous example, the
+            <ulink url='&YOCTO_DOCS_REF_URL;#var-BB_GENERATE_MIRROR_TARBALLS'><filename>BB_GENERATE_MIRROR_TARBALLS</filename></ulink>
+            variable causes the OpenEmbedded build system to generate tarballs
+            of the Git repositories and store them in the
+            <ulink url='&YOCTO_DOCS_REF_URL;#var-DL_DIR'><filename>DL_DIR</filename></ulink>
+            directory.
+            Due to performance reasons, generating and storing these tarballs
+            is not the build system's default behavior.

             variable.
