+# Bigtable Module
+This module is used to provision a basic bigtable instance with a single cluster in it.
+NOTE: this is only meant for internal usage, as it has some logic that is specific to Tamr's GCP setup.
+This repo follows the [terraform standard module structure](https://www.terraform.io/docs/modules/index.html#standard-module-structure).
+
+# Examples
+## Basic
+Inline example implementation of the module.  This is the most basic example of what it would look like to use this module.
+```
+module "bigtable" {
+  source = "./shared_files/modules/gcp-bigtable"
+  name   = "tamr"
+}
+```
+
+# Resources Created
+* A production bigtable instance
+
+# Variables 
+## Inputs
+Write your Terraform module inputs.
+* `name` (required): The name of the bigtable instance
+* `initial_num_nodes` (optional): The number nodes to start the cluster with
+* `zone` (optional): The zone for the cluster to be created in
+* `storage_type` (optional): The storage type for the cluster
+
+# References
+This repo is based on:
+* [terraform standard module structure](https://www.terraform.io/docs/modules/index.html#standard-module-structure)
+* [templated terraform module](https://github.com/tmknom/template-terraform-module)
