+## texlive vs texlive-full
+
+Version 1 of this image was using the
+[texlive-full](https://packages.ubuntu.com/search?keywords=texlive-full&searchon=names&exact=1&suite=all&section=all)
+Ubuntu package to include as much TeX Live packages pre-installed as
+possible. But the resulting docker image was over 4 GB making it slow
+to download and breaking some CI/CD disk limits (including the free
+tier of GitHub Actions that I use). To keep the image usable by as many
+people as possible, I decided with version 2 and above to switch
+to the default
+[texlive](https://packages.ubuntu.com/search?keywords=texlive&searchon=names&exact=1&suite=all&section=all)
+package.
+
+If you need more TeX Live packages, you have the following options:
+- use version 1 of this docker image (i.e. leplusorg/latex:1).
+- install texlive-full at runtime before running the latex command
+that you need:
+
+```batch
+docker run --rm -t --net=none -v "%cd%:/tmp" leplusorg/latex sh -c "apt-get update && apt-get install --no-install-recommends -y texlive-full && latexmk -outdir=/tmp -pdf /tmp/foo.tex"
+```

 ## Request new tool
 
 Please use [this link](https://github.com/leplusorg/docker-latex/issues/new?assignees=thomasleplus&labels=enhancement&template=feature_request.md&title=%5BFEAT%5D) (GitHub account required) to request that a new tool be added to the image. I am always interested in adding new capabilities to these images.
