+# fntbld-oci
+
+A container image with font-building tools pre-installed:
+
+- **FontForge** — scriptable font editor
+- **ttfautohint** — auto-hinter for TrueType fonts
+- **fontTools** — Python library for manipulating font files
+
+The image contains no project-specific files. Mount or clone your font project into `/build` at runtime.
+

+podman build -t fntbld-oci .

+
+## Pull from GitHub Container Registry
+
+```bash

+```
+
+## Usage
+
+From your font project directory:
+
+```bash
+podman run --rm -v .:/build ghcr.io/nicoverbruggen/fntbld-oci python3 build.py
+```
+
+## Debugging
