+# into the INSTALL.md file.
+
+## [START INSTALL.md]
+
+# First install the development tools and OpenSSL. The development tools
+# distributed with CentOS (notably CMake) are too old to build
+# `cpp-cmakefiles`. In these instructions, we use `cmake3` obtained from
+# [Software Collections](https://www.softwarecollections.org/).
+
+# ```bash
+RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
+RUN yum install -y centos-release-scl
+RUN yum-config-manager --enable rhel-server-rhscl-7-rpms
+RUN yum makecache && \
+    yum install -y automake cmake3 curl-devel gcc gcc-c++ git libtool \
+        make openssl-devel pkgconfig tar wget which zlib-devel
+RUN ln -sf /usr/bin/cmake3 /usr/bin/cmake && ln -sf /usr/bin/ctest3 /usr/bin/ctest
+# ```
+
+# #### Protobuf
+
+# Likewise, manually install protobuf:
+
+# ```bash
+WORKDIR /var/tmp/build
+RUN wget -q https://github.com/google/protobuf/archive/v3.9.0.tar.gz
+RUN tar -xf v3.9.0.tar.gz
+WORKDIR /var/tmp/build/protobuf-3.9.0/cmake
+RUN cmake \
+        -DCMAKE_BUILD_TYPE=Release \
+        -DBUILD_SHARED_LIBS=yes \
+        -Dprotobuf_BUILD_TESTS=OFF \
+        -H. -Bcmake-out
+RUN cmake --build cmake-out --target install -- -j $(nproc)
+RUN ldconfig
+# ```
+
+# #### c-ares
+
+# Recent versions of gRPC require c-ares >= 1.11, while CentOS-7
+# distributes c-ares-1.10. Manually install a newer version:
+
+# ```bash
+WORKDIR /var/tmp/build
+RUN wget -q https://github.com/c-ares/c-ares/archive/cares-1_15_0.tar.gz
+RUN tar -xf cares-1_15_0.tar.gz
+WORKDIR /var/tmp/build/c-ares-cares-1_15_0
+RUN ./buildconf && ./configure && make -j $(nproc)
+RUN make install
+RUN ldconfig
+# ```
+
+# #### gRPC
+
+# Can be manually installed using:
+
+# ```bash
+WORKDIR /var/tmp/build
+RUN wget -q https://github.com/grpc/grpc/archive/v1.22.0.tar.gz
+RUN tar -xf v1.22.0.tar.gz
+WORKDIR /var/tmp/build/grpc-1.22.0
+ENV PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig
+ENV LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64
+ENV PATH=/usr/local/bin:${PATH}
+RUN make -j $(nproc)
+RUN make install
+RUN ldconfig
+# ```
+
+FROM devtools AS install
+
+# #### googleapis
+
+# Finally we can install `googleapis`.
+
+# ```bash
+WORKDIR /home/build/cpp-cmakefiles
+COPY . /home/build/cpp-cmakefiles
+RUN cmake -H. -Bcmake-out
+RUN cmake --build cmake-out -- -j $(nproc)
+WORKDIR /home/build/cpp-cmakefiles/cmake-out
+RUN cmake --build . --target install
+# ```
+
