+# Configuring the builder.

+$ sudo apt install podman podman-docker jq
+```
+## Add services.
+
+```
+$ sudo cp self-hosted-builder/*.service /etc/systemd/system/
+$ sudo systemctl daemon-reload
+```
+
+## Rebuild the image
+
+First build ppc64le builder image `docker.io/pytorch/manylinuxppc64le-builder`,
+using following commands:
+
+```
+$ cd ~
+$ git clone https://github.com/pytorch/pytorch
+$ cd pytorch
+$ git submodule update --init --recursive
+$ GPU_ARCH_TYPE=cpu-ppc64le "$(pwd)/.ci/docker/manywheel/build.sh" manylinuxppc64le-builder
+$ docker image tag localhost/pytorch/manylinuxppc64le-builder docker.io/pytorch/manylinuxppc64le-builder:cpu-ppc64le
+$ docker image save -o ~/manywheel-ppc64le.tar docker.io/pytorch/manylinuxppc64le-builder:cpu-ppc64le
+```
+
+Next step is to build `actions-runner` image using:
+
+```
+## clone gaplib repo (https://github.com/anup-kodlekere/gaplib.git) and copy runner-sdk-8.ppc64le patch from gaplib/build-files into pytorch/.github\scripts\ppc64le-ci\self-hosted-builder
+
+$ cd self-hosted-builder
+$ sudo docker build \

+      --build-arg RUNNERPATCH="runner-sdk-8.ppc64le.patch" \
+      -t iiilinuxibmcom/actions-runner.<name> \
+      .
+```
+
+Now prepare all necessary files for runner registration:
+
+```
+$ sudo mkdir -p /etc/actions-runner/<name>
+$ sudo chmod 755 /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 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.
