+# everest_release.json
+
+A JSON file containing a subset of installed packages can be added to your
+image `/etc/everest/everest_release.json` by adding the following line to
+your image recipes
+
+```
+inherit everest_version_file
+```
+
+`everest_version_file.bbclass` queries the installed packages and creates the
+release JSON file by appending `do_everest_generate_version` to
+the `ROOTFS_POSTPROCESS_COMMAND` variable.
+
+`everest_version_file.bbclass` contains a list of packages to include.
+
+This list can be extended via the `EVEREST_RELEASE_PACKAGES` variable as a
+space separated list. For example in `local.conf`
+
+```
+everest_RELEASE_PACKAGES += "systemd tcpdump"
+```
+
+Note that packages need to be listed in `RDEPENDS`, or `IMAGE_INSTALL` to be
+available for inclusion.
