 ## How to set up Github Action runner
 1. Clone this repo and copy out the files in this directory to one level above
-```shell
-mkdir github-runner
-
-cd github-runner
-
-git clone https://github.com/filecoin-project/curio.git
-git clone https://github.com/filecoin-project/boost.git
-
-cp -r boost/.github/utils/* .
-```
+    ```shell
+    mkdir github-runner
+    
+    cd github-runner
+    
+    git clone https://github.com/filecoin-project/curio.git
+    git clone https://github.com/filecoin-project/boost.git
+    
+    cp -r boost/.github/utils/* .
+    ```
 2. Copy the Dockerfile
-
-```shell
-copy boost/.github/image/Dockerfile .
-```
+    ```shell
+    copy boost/.github/image/Dockerfile .
+    ```
 
 3. Create new image
-
-```shell
-docker buildx build -t curio/github-runner:latest .
-```
+    ```shell
+    docker buildx build -t curio/github-runner:latest .
+    ```
 
 4. Create systemd file. Please ensure to equal number files for Boost and Curio. If server can host 10 runner then 5 should be for Boost and 5 for Curio.
-
-```shell
-for i in {1..5}; do cat github-actions-runner.service | sed "s/NUM/$i/g" > github-actions-runner$i.service; done
-for i in {6..10}; do cat github-actions-runner.service | sed 's/curio-/boost-/g' | sed "s/NUM/$i/g" > github-actions-runner$i.service; done
-for i in {1..10}; do install -m 644 github-actions-runner$i.service /etc/systemd/system/ ; done
-systemctl daemon-reload
-```
+    ```shell
+    for i in {1..5}; do cat github-actions-runner.service | sed "s/NUM/$i/g" > github-actions-runner$i.service; done
+    for i in {6..10}; do cat github-actions-runner.service | sed 's/curio-/boost-/g' | sed "s/NUM/$i/g" > github-actions-runner$i.service; done
+    for i in {1..10}; do install -m 644 github-actions-runner$i.service /etc/systemd/system/ ; done
+    systemctl daemon-reload
+    ```
 5. Add the token to ENV files
+    ```shell
+    vi boost-github-actions-runner.env
+    ```
+   add the token
+    ```text
+    LABELS=docker
+    ACCESS_TOKEN=<TOKEN> --- Replace with a PAT
+    ```
+   
 6. Copy the ENV files to /etc
-
-```shell
-cp boost-github-actions-runner.env
-cp curio-github-actions-runner.env
-```
+    ```shell
+    cp boost-github-actions-runner.env /etc/
+    cp curio-github-actions-runner.env /etc/
+    ```
 
 7. Start and Enable the services
-```shell
-for i in {1..10}; do systemctl start github-actions-runner$i.service; done
-for i in {1..10}; do systemctl status github-actions-runner$i.service; done
-for i in {1..10}; do systemctl enable github-actions-runner$i.service; done
-```
+    ```shell
+    for i in {1..10}; do systemctl start github-actions-runner$i.service; done
+    for i in {1..10}; do systemctl status github-actions-runner$i.service; done
+    for i in {1..10}; do systemctl enable github-actions-runner$i.service; done
+    ```
 
 8. Verify that new runners are visible in the repo.
 
 ## Set up docker image creator
 1. Make the script executable
-```shell
-cd github-runner
-chmod +x create-runner-image.sh
-```
+    ```shell
+    cd github-runner
+    chmod +x create-runner-image.sh
+    ```
 2. Create a cron job to update the image every day
-```shell
-crontab -e
-```
-
-```shell
-0 0 * * * /root/github-runner/create-runner-image.sh
-```
+    ```shell
+    crontab -e
+    ```
+    add the below line
+    ```shell
+    0 0 * * * /root/github-runner/create-runner-image.sh
+    ```
