# Google Cloud Storage

The **Google Cloud Storage (GCS)** data source in Epsilla allows users to seamlessly connect their GCS bucket to manage documents stored in the cloud. This type of data source is ideal for adding dynamic or shared content, such as PDFs, images, or structured files, to the knowledge base for retrieval purposes.

### **Select Knowledge Base Type**

Choose **Google Cloud Storage** to continue.

### **Knowledge Base Name**

Provide a Knowledge Base Name. A valid name should start with a letter or '\_', and can contain only letters, digits, underscores, and whitespaces (e.g., `MyGCSDocs`).

### **Configure GCS Connection**

Provide the required details to connect to your GCS bucket:

* **Service Account Credential**: Paste the content from your GCP `credentials.json` file.
* **Bucket**: Specify the name of your GCS bucket (e.g., `epsilla-gcs-demo`).
* **Prefix** *(Optional)*: Enter the folder path within the bucket if you want to sync specific folders. Leave blank to sync the entire bucket.

### **Data Processing**

Once the required information is entered, click **Create** to start the knowledge base creation process. Epsilla will automatically process the files (under the hood, Epsilla will load the files, chunk them, and embed them into vectors).

After the data is processed, the list of documents imported from GCS will be visible in the **Loaded Files** section. Files that are ready for use will be marked as **Ready**, while those still processing will show a status of **Processing data**.

You can update or edit your Google Cloud Storage configuration by navigating to the **Data Sources** tab under your knowledge base.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://epsilla-inc.gitbook.io/epsilladb/knowledge-base/google-cloud-storage.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
