Run the following command to install the `cbt` CLI : \n\n gcloud components install cbt\n\n\u003cbr /\u003e\n\nCreate a Bigtable instance\n\n1. Open the **Create instance** page in the Google Cloud console.\n\n [Create an instance](https://console.cloud.google.com/bigtable/create-instance)\n2. For **Instance name** , enter `Quickstart instance`.\n\n3. For **Instance ID** , enter `quickstart-instance`.\n\n4. Click **Continue**.\n\n5. For **Storage type** , select **SSD**.\n\n6. Click **Continue**.\n\n7. For **Cluster ID** , enter `quickstart-instance-c1`.\n\n8. For **Region**, select a region near you.\n\n9. For **Zone** , select **Any**.\n\n10. For **Node scaling mode** , choose **Manual allocation**.\n\n11. For **Quantity** , select **1**.\n\n12. Click **Create** to create the instance.\n\nConnect to your instance\n\n1. Configure the\n `cbt` CLI\n to use your project and instance by creating a\n `.cbtrc` file, replacing \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the ID\n for the project where you created your Bigtable instance:\n\n ```\n echo project = PROJECT_ID \u003e\u003e ~/.cbtrc && echo instance = quickstart-instance \u003e\u003e ~/.cbtrc\n ```\n2. Verify that you set up the `.cbtrc` file correctly:\n\n ```\n cat ~/.cbtrc\n ```\n\n The terminal displays the contents of the `.cbtrc` file, which looks similar\n to the following: \n\n ```\n project = PROJECT_ID\n instance = quickstart-instance\n ```\n\n Now you can use the\n `cbt` CLI\n with your instance.\n\nRead and write data\n\nBigtable stores data in *tables* , which contain *rows* . Each row\nis identified by a *row key*.\n\nData in a row is organized into *column families* , which are groups of columns.\nA *column qualifier* identifies a single column within a column family.\n\nThere can be multiple time-stamped cells at the intersection of\na row and column.\n\n1. Create a table named `my-table`.\n\n ```\n cbt createtable my-table\n ```\n2. List your tables:\n\n ```\n cbt ls\n ```\n\n The command displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n my-table\n ```\n\n \u003cbr /\u003e\n\n3. Add one column family named `cf1`:\n\n ```\n cbt createfamily my-table cf1\n ```\n4. List your column families:\n\n ```\n cbt ls my-table\n ```\n\n The command displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n Family Name GC Policy\n ----------- ---------\n cf1 \u003cnever\u003e\n ```\n\n \u003cbr /\u003e\n\n5. Write the values `test-value1` and `test-value2` to the row `r1`, using the\n column family `cf1` and the column qualifier `c1`:\n\n ```\n cbt set my-table r1 cf1:c1=test-value1\n cbt set my-table r1 cf1:c1=test-value2\n ```\n6. Use the `cbt read` command to read the data you added to the table:\n\n ```\n cbt read my-table\n ```\n\n The shell displays output similar to the following:\n\n \u003cbr /\u003e\n\n ```\n ----------------------------------------\n r1\n cf1:c1 @ 2023/03/22-06:56:11.323000\n \"test-value1\"\n cf1:c1 @ 2023/03/22-06:56:04.361000\n \"test-value2\"\n ```\n\n \u003cbr /\u003e\n\n Two timestamped values are stored for the same column in row `r1`.\n | **Note:** In this quickstart you set only two cells, but Bigtable lets you set up to 10,000 cells in a single write request.\n\nClean up\n\nTo avoid incurring charges to your Google Cloud account for the resources\nused in this quickstart, delete the instance. Deleting the `.cbtrc` file leaves\nyou ready to work on a different project.\n\n1. Delete the table `my-table`:\n\n ```\n cbt deletetable my-table\n ```\n2. Delete the instance:\n\n ```\n cbt deleteinstance quickstart-instance\n ```\n3. Delete the `.cbtrc` file:\n\n ```\n rm ~/.cbtrc\n ```\n\n \u003cbr /\u003e\n\n4. Optional: Revoke credentials from the gcloud CLI:\n\n ```\n gcloud auth revoke\n ```\n\nWhat's next\n\n- Work through a [Bigtable codelab](https://codelabs.developers.google.com/codelabs/cloud-bigtable-intro-java/index.html).\n- View the [`cbt` CLI\n reference documentation](/bigtable/docs/cbt-reference).\n- See sample source code for a [fraud detection use case](https://github.com/GoogleCloudPlatform/java-docs-samples/tree/main/bigtable/use-cases/fraudDetection).\n- Write a Hello World application in [C#](/bigtable/docs/samples-c-sharp-hello), [C++](/bigtable/docs/samples-cpp-hello), [Go](/bigtable/docs/samples-go-hello), [Java](/bigtable/docs/samples-java-hello-world), [Node.js](/bigtable/docs/samples-nodejs-hello), [PHP](/bigtable/docs/samples-php-hello), [Python](/bigtable/docs/samples-python-hello), [Ruby](/bigtable/docs/samples-ruby-hello), or using the [HBase client for Java](/bigtable/docs/samples-hbase-java-hello)."]]
