+Creating tables is one of the most complicated operations for many databases because you might need to:
+
 * Manually specify the engine
 * Manually specify the indexes
 * And even specify the data partitions or data shard
-
-In Databend, you **don't need to specify any of these**, one of Databend's design goals is to make it easier to use.
 
-## Syntax
+Databend aims to be easy to use by design and does NOT require any of those operations when you create a table. Moreover, the CREATE TABLE statement provides these options to make it much easier for you to create tables in various scenarios:
+
+- [CREATE TABLE](#create-table): Creates a table from scratch.
+- [CREATE TABLE ... LIKE](#create-table--like): Creates a table with the same column definitions as an existing one.
+- [CREATE TABLE ... AS](#create-table--as): Creates a table and inserts data with the results of a SELECT query.
+- [CREATE TRANSIENT TABLE](#create-transient-table): Creates a table without storing its historical data for Time Travel.
+- [CREATE TABLE ... SNAPSHOT_LOCATION](#create-table--snapshot_location): Creates a table and inserts data with a snapshot file.
+- [CREATE TABLE ... EXTERNAL_LOCATION](#create-table--external_location): Creates a table and specifies an S3 bucket for the data storage instead of the FUSE engine.

+## CREATE TABLE ... EXTERNAL_LOCATION
+
+Creates a table and specifies an S3 bucket for the data storage instead of the FUSE engine.
+
+Databend stores the table data in the location configured in the file `databend-query.toml` by default. This option enables you to store the data (in parquet format) in a table in another bucket instead of the default one.
+
+Syntax:
+```sql
+CREATE TABLE [IF NOT EXISTS] [db.]table_name
+
+    <column_name> <data_type> [ NOT NULL | NULL] [ { DEFAULT <expr> }],
+    <column_name> <data_type> [ NOT NULL | NULL] [ { DEFAULT <expr> }],

+CONNECTION = (AWS_KEY_ID = '<your_aws_key_id>' AWS_SECRECT_KEY = '<your_aws_secret_key>' ENDPOINT_URL = '<endpoint_url>');
+```
+
+| Parameter  | Description | Required |
+| ----------- | ----------- | --- |
+| `s3://<bucket>/[<path>]`  | Files are in the specified external location (S3-like bucket) | YES |
+| `AWS_KEY_ID = '<your_aws_key_id>' AWS_SECRECT_KEY = '<your_aws_secret_key>'`  | The credentials for connecting to AWS and accessing the private/protected S3 bucket where the files to load are staged. |  Optional |
+| `ENDPOINT_URL = '<endpoint_url>'`  | S3-compatible endpoint URL like MinIO. Default: `https://s3.amazonaws.com` |  Optional |
