= Cloning the project
This project uses https://git-scm.com/book/en/v2/Git-Tools-Submodules[GitHub Submodules] to include the https://github.com/riscv/docs-resources[RISC-V docs-resources project] to achieve a common look and feel.
When cloning this repository for the first time, you must either use
git clone --recurse-submodules
or execute git submodule init
and git submodule update
after the clone to populate the docs-resources directory. Failure to clone the submodule, will result
in the PDF build fail with an error message like the following:
$ make
asciidoctor-pdf \
-a toc \
-a compress \
-a pdf-style=docs-resources/themes/riscv-pdf.yml \
-a pdf-fontsdir=docs-resources/fonts \
--failure-level=ERROR \
-o profiles.pdf profiles.adoc
