+# Bigtable Tools Sample
+
+## Introduction
+
+This sample agent demonstrates the Bigtable first-party tools in ADK,
+distributed via the `google.adk.tools.bigtable` module. These tools include:
+
+1. `bigtable_list_instances`
+
+  Fetches Bigtable instance ids in a Google Cloud project.
+
+1. `bigtable_get_instance_info`
+
+  Fetches metadata information about a Bigtable instance.
+
+1. `bigtable_list_tables`
+
+  Fetches table ids in a Bigtable instance.
+
+1. `bigtable_get_table_info`
+
+  Fetches metadata information about a Bigtable table.
+
+1. `bigtable_execute_sql`
+
+  Runs a DQL SQL query in Bigtable database.
+
+## How to use
+
+Set up environment variables in your `.env` file for using
+[Google AI Studio](https://google.github.io/adk-docs/get-started/quickstart/#gemini---google-ai-studio)
+or
+[Google Cloud Vertex AI](https://google.github.io/adk-docs/get-started/quickstart/#gemini---google-cloud-vertex-ai)
+for the LLM service for your agent. For example, for using Google AI Studio you
+would set:
+
+* GOOGLE_GENAI_USE_VERTEXAI=FALSE
+* GOOGLE_API_KEY={your api key}
+
+### With Application Default Credentials
+
+This mode is useful for quick development when the agent builder is the only
+user interacting with the agent. The tools are run with these credentials.
+
+1. Create application default credentials on the machine where the agent would
+be running by following https://cloud.google.com/docs/authentication/provide-credentials-adc.
+
+1. Set `CREDENTIALS_TYPE=None` in `agent.py`
+
+1. Run the agent
+
+### With Service Account Keys
+
+This mode is useful for quick development when the agent builder wants to run
+the agent with service account credentials. The tools are run with these
+credentials.
+
+1. Create service account key by following https://cloud.google.com/iam/docs/service-account-creds#user-managed-keys.
+
+1. Set `CREDENTIALS_TYPE=AuthCredentialTypes.SERVICE_ACCOUNT` in `agent.py`
+
+1. Download the key file and replace `"service_account_key.json"` with the path
+
+1. Run the agent
+
+### With Interactive OAuth
+
+1. Follow
+https://developers.google.com/identity/protocols/oauth2#1.-obtain-oauth-2.0-credentials-from-the-dynamic_data.setvar.console_name.
+to get your client id and client secret. Be sure to choose "web" as your client
+type.
+
+1.  Follow https://developers.google.com/workspace/guides/configure-oauth-consent
+    to add scope "https://www.googleapis.com/auth/bigtable.admin" and
+    "https://www.googleapis.com/auth/bigtable.data" as declaration, this is used
+    for review purpose.
+
+1.  Follow
+    https://developers.google.com/identity/protocols/oauth2/web-server#creatingcred
+    to add http://localhost/dev-ui/ to "Authorized redirect URIs".
+
+    Note: localhost here is just a hostname that you use to access the dev ui,
+    replace it with the actual hostname you use to access the dev ui.
+
+1.  For 1st run, allow popup for localhost in Chrome.
+
+1.  Configure your `.env` file to add two more variables before running the
+    agent:
+
+    *   OAUTH_CLIENT_ID={your client id}
+    *   OAUTH_CLIENT_SECRET={your client secret}
+
+    Note: don't create a separate .env, instead put it to the same .env file that
