+# `d.xr.to/xbps-builder`
+
+```bash
+docker pull d.xr.to/xbps-builder
+```
+
+A simple pre-configured container to build void packages in, [void-linux/void-packages](https://github.com/void-linux/void-packages)
+is checked out in `/_workdir` which is also the current workdir
+
+Building an image inside a Dockerfile and installing it
+it in a target docker container looks like the following
+
+```Dockerfile
+FROM d.xr.to/xbps-builder AS builder
+RUN git pull
+RUN ./xbps-src pkg docker
+FROM d.xr.to/base
+COPY --from=builder /_workdir/hostdir /tmp/xbps
+RUN xbps-install -SyR /tmp/xbps docker \
+      && xbps-remove -Oo \
+      && rm -rf /var/cache/xbps/* /tmp/xbps
+```
+
+# Warning
+
+This xbps-builder is bootstrapped with some very bad magic, so if you hit an issue, please create an issue!
