 ## Steps to use scripts
+### Deploy Single dataset with github actions
+The github actions below will automatically build and deploy a single dataset to gh-pages branch. Folow the steps below to achieve this:
 
+**Step 1:** In the dataset repository you want to deploy, create a github secret with the name `PORTAL_REPO_NAME` and the value should be the name of the repository. 
+
+See steps on creating a secret [here](https://docs.github.com/en/actions/reference/encrypted-secrets)
+
+<img src="./assets/secrets.png" />
+
+**Step 2:** Clone/Pull the dataset repository you want deploy:
+
+```bash
+git clone https://github.com/datasets/finance-vix
+```
+**Step 3:** Create a `.github/workflow` directory and add a `main.yml` file with the following content:
+
+```bash
+name: github pages
+
+on:
+  push:
+    branches:
+      - master
+      - main
+
+jobs:
+  run:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v2
+    - name: Setup Node
+      uses: actions/setup-node@v2.1.2
+      with:
+        node-version: '12.x'
+
+    - name: Build datasets
+      env:
+        PORTAL_REPO_NAME: ${{ secrets.PORTAL_REPO_NAME }}
+      run: |
+        curl https://raw.githubusercontent.com/datopian/portal.js/main/scripts/single-dataset-no-commit.sh > portal.sh 
+        git config --local user.email "$(git log --format='%ae' HEAD^!)"
+        git config --local user.name "$(git log --format='%an' HEAD^!)"
+        source ./portal.sh
+
+```
+You can see/download the action file [here]("./actions/single-dataset-ssg.yml")
+
+**Step 3:** Commit and push your code:
+```bash
+git add .
+git commit -m "Build dataset page"
+git push 
+```
+
+**Step 4:**
+Wait for a while as your page builds, and once you see the green check mark, navigate to your repository's github `pages` in settings, set the `source` to `gh-pages` and folder to `/root`:

+Open your deployed site at `https://<your github username>/github.io/<dataset repo name>/index.html`
