-## Source Files
-
-The `librefonts/novaflat` repo contains:
-- `src/NovaFlat.sfd` — FontForge source file (primary editable source)
-- `NovaFlat.ttf.*.ttx` — TTX-decomposed TTF tables (generated artifact)
-- `src/VERSIONS.txt` — records version
-- `METADATA.json`, `FONTLOG.txt`, `OFL.txt`, `DESCRIPTION.en_us.html`

-The `.sfd` file is the authoritative source.

 ## Build System
 
-The repo uses the legacy `fontbakery-build.py` pipeline (circa 2014), driven by a `.travis.yml` CI config. This system is obsolete. No `Makefile` or modern build script is present.
-
-## config.yaml Status
-
-No `config.yaml` exists in the `librefonts/novaflat` repo or in `ofl/novaflat/` in google/fonts. One would need to be created for any rebuild attempt.

 ## Notes
 
 - The Google Fonts binary (`NovaFlat.ttf`) corresponds to version 2.000.
 - The designer released a substantially redesigned Nova Flat (v3.x with Bold/Oblique variants) in 2020 at `wmk69/Nova`, but this has not been adopted by Google Fonts.
 - Designer: Wojciech Kalinowski (wmk69), wmk69@o2.pl.
