+To build this project, few additional steps are required:
+
+1. Clone 'rootstrap-data-common' and 'rootstrap' projects from tizen.org (branch tizen)
+ https://review.tizen.org/gerrit/admin/repos/platform/hal/backend/rootstrap-data-common,general
+ https://review.tizen.org/gerrit/admin/repos/platform/hal/backend/rootstrap,general
+
+2. Apply below patch to 'rootstrap-data-common' (this patch will add libteec header/library to hal rootstrap)
+ https://review.tizen.org/gerrit/c/platform/hal/backend/rootstrap-data-common/+/321678
+ or local copy from main dir in case of inactive link (0001-Add-libteec-library-to-hal-rootstrap.patch)
+
+3. Build 'rootstrap-data-common' and after that 'rootstrap'
+
+4. Build 'security-keys'
+
+In case of GBM, above patch (or similar) should be applied in hal-roostrap-data-[gbm] project.
