+To use GmailLoader you must install the extra dependencies with `pip install --upgrade embedchain[gmail]`.
+
+The `source` must be a valid Gmail search query, you can refer `https://support.google.com/mail/answer/7190?hl=en` to build a query.
+
+To load Gmail messages, you MUST use the data_type as `gmail`. Otherwise the source will be detected as simple `text`.
+
+To use this you need to save `credentials.json` in the directory from where you will run the loader. Follow these steps to get the credentials
+
+1. Go to the [Google Cloud Console](https://console.cloud.google.com/apis/credentials).
+2. Create a project if you don't have one already.
+3. Create an `OAuth Consent Screen` in the project. You may need to select the `external` option.
+4. Make sure the consent screen is published.
+5. Enable the [Gmail API](https://console.cloud.google.com/apis/api/gmail.googleapis.com)
+6. Create credentials from the `Credentials` tab.
+7. Select the type `OAuth Client ID`.
+8. Choose the application type `Web application`. As a name you can choose `embedchain` or any other name as per your use case.
+9. Add an authorized redirect URI for `http://localhost:8080/`.
+10. You can leave everything else at default, finish the creation.
+11. When you are done, a modal opens where you can download the details in `json` format.
+12. Put the `.json` file in your current directory and rename it to `credentials.json`

+
+Embedchain lets you build data pipelines on your own data sources and deploy it in production in less than a minute. It can load, index, retrieve, and sync any unstructured data.
+
+Install embedchain python package:
+
+```bash
+pip install embedchain
+```
+
+Creating a pipeline involves 3 steps:
+
+<Steps>
+  <Step title="⚙️ Import pipeline instance">
+```python
+from embedchain import Pipeline
+p = Pipeline(name="Elon Musk")
+```
+  </Step>
+
+  <Step title="🗃️ Add data sources">
+```python
+# Add different data sources
+p.add("https://en.wikipedia.org/wiki/Elon_Musk")
+p.add("https://www.forbes.com/profile/elon-musk")
+# You can also add local data sources such as pdf, csv files etc.
+# p.add("/path/to/file.pdf")
+```
+  </Step>
+  <Step title="💬 Deploy your pipeline to Embedchain platform">
+```python
+p.deploy()
+```
+  </Step>
+</Steps>
+
+That's it. Now, head to the [Embedchain platform](https://app.embedchain.ai) and your pipeline is available there. Make sure to set the `OPENAI_API_KEY` 🔑 environment variable in the code.
+
+After you deploy your pipeline to Embedchain platform, you can still add more data sources and update the pipeline multiple times.
