+## Training Code
+As described in the technical reports, there are two stages for training:
+one for the navigation, and the other for the frag.
+We provide the corresponding `.yml.jinja2` files here: [for navigation](vdtr-navi-open.yml.jinja2) and [for frag](vdtr-frag-open.yml.jinja2), respectively.

+# stop
