+# Configuring the builder.
+
+## Install prerequisites.
+
+```
+$ sudo dnf install podman podman-docker jq
+```
+
+## Add services.
+
+```
+$ sudo cp self-hosted-builder/*.service /etc/systemd/system/
+$ sudo systemctl daemon-reload
+```
+
+## Download qemu-user-static image
+
+```
+# sudo docker pull docker.io/iiilinuxibmcom/qemu-user-static:6.1.0-1
+```
+
+## Autostart the x86_64 emulation support.
+
+```
+$ sudo systemctl enable --now qemu-user-static
+```
+
+## Rebuild the image
+
+First build s390x builder image `docker.io/pytorch/manylinuxs390x-builder`,
+using following commands:
+
+```
+$ cd ~
+$ git clone https://github.com/pytorch/pytorch
+$ cd pytorch
+$ git submodule update --init --recursive
+$ GPU_ARCH_TYPE=cpu-s390x "$(pwd)/.ci/docker/manywheel/build.sh" manylinuxs390x-builder
+$ docker image tag localhost/pytorch/manylinuxs390x-builder docker.io/pytorch/manylinuxs390x-builder:cpu-s390x
+$ docker image save -o ~/manywheel-s390x.tar docker.io/pytorch/manylinuxs390x-builder:cpu-s390x
+```
+
+Next step is to build `actions-runner` image using:
+
+```
+$ cd self-hosted-builder
+$ sudo docker build \
+      --pull \
+      -f actions-runner.Dockerfile \
+      -t iiilinuxibmcom/actions-runner.<name> \
+      .
+```
+
+If there are failures, ensure that selinux doesn't prevent it from working.
+In worst case, selinux can be disabled with `setenforce 0`.
+
+Now prepare all necessary files for runner registration:
+
+```
+$ sudo mkdir -p /etc/actions-runner/<name>
+$ sudo chmod 700 /etc/actions-runner/<name>
+$ sudo /bin/cp <github_app_private_key_file> /etc/actions-runner/<name>/key_private.pem
+$ sudo echo <github_app_id> | sudo tee /etc/actions-runner/<name>/appid.env
+$ sudo echo <github_app_install_id> | sudo tee /etc/actions-runner/<name>/installid.env
+$ sudo echo NAME=<worker_name> | sudo tee    /etc/actions-runner/<name>/env
+$ sudo echo ORG=<github_org>   | sudo tee -a /etc/actions-runner/<name>/env
+$ cd self-hosted-builder
+$ sudo /bin/cp helpers/*.sh /usr/local/bin/
+$ sudo chmod 755 /usr/local/bin/app_token.sh /usr/local/bin/gh_token_generator.sh
+```
+
+## Autostart the runner.
+
+```
+$ sudo systemctl enable --now actions-runner@$NAME
+```
