 # DuckDB Delta Extension
+
 This is the experimental DuckDB extension for [Delta](https://delta.io/). It is built using the (also experimental) 
 [Delta Kernel](https://github.com/delta-incubator/delta-kernel-rs). The extension (currently) offers **read** support for delta
 tables, both local and remote.
 
-# Supported platforms
+## Supported platforms
+
 The supported platforms are:
+
 - `linux_amd64` and `linux_amd64_gcc4` and `linux_arm64`
 - `osx_amd64` and `osx_arm64`
 - `windows_amd64`
 
 Support for the [other](https://duckdb.org/docs/extensions/working_with_extensions#platforms) DuckDB platforms is 
 work-in-progress
 
-# How to use
-**NOTE: this extension requires the DuckDB v0.10.3 or higher**
+## How to use
+
+> [!NOTE]
+> This extension requires the DuckDB v0.10.3 or higher
 
 This extension is distributed as a binary extension. To use it, simply use one of its functions from DuckDB and the extension will be autoloaded:
+
 ```SQL
 FROM delta_scan('s3://some/delta/table');
 ```
 
-Note that using DuckDB [Secrets](https://duckdb.org/docs/configuration/secrets_manager.html) for S3 authentication is supported:
+To scan a local table, use the full path prefixes with `file://`
+
+```SQL
+FROM delta_scan('file:///some/path/on/local/machine');
+```
+
+## Cloud Storage authentication
+
+Note that using DuckDB [Secrets](https://duckdb.org/docs/configuration/secrets_manager.html) for Cloud authentication is supported.
+
+### S3 Example
 
 ```SQL
-CREATE SECRET (TYPE S3, provider credential_chain);
+CREATE SECRET (
+  TYPE S3,
+  PROVIDER CREDENTIAL_CHAIN
+);
 FROM delta_scan('s3://some/delta/table/with/auth');
 ```
 
-To scan a local table, use the full path prefixes with `file://`
+### Azure Example
+
 ```SQL
-FROM delta_scan('file:///some/path/on/local/machine');
+CREATE SECRET (
+    TYPE AZURE,
+    PROVIDER CREDENTIAL_CHAIN,
+    CHAIN 'cli',
+    ACCOUNT_NAME 'mystorageaccount'
+);
+FROM delta_scan('abfss://some/delta/table/with/auth');
 ```
 
-# Features
+## Features
+
 While still experimental, many (scanning) features/optimizations are already supported in this extension as it reuses most of DuckDB's
 regular parquet scanning logic:
+
 - multithreaded scans and parquet metadata reading
 - data skipping/filter pushdown
   - skipping row-groups in file (based on parquet metadata)
@@ -43,24 +71,30 @@ regular parquet scanning logic:

-# Building
+## Building
+
 See the [Extension Template](https://github.com/duckdb/extension-template) for generic build instructions
 
-# Running tests
+## Running tests
+
 There are various tests available for the delta extension:
+
 1. Delta Acceptence Test (DAT) based tests in `/test/sql/dat`
 2. delta-kernel-rs based tests in `/test/sql/delta_kernel_rs`
 3. Generated data based tests in `tests/sql/generated` (generated using [delta-rs](https://delta-io.github.io/delta-rs/), [PySpark](https://spark.apache.org/docs/latest/api/python/index.html), and DuckDB)
 
 To run the first 2 sets of tests:
+
 ```shell
 make test_debug
 ```
+
 or in release mode
+
 ```shell
 make test
 ```

+# Benchmarking the Delta Extension
+
+## Basics
+A primitive benchmarking suite exists for the Delta extension.
+
+To run the benchmarks, firstly run the build using:
+```shell
+BUILD_BENCHMARK=1 make
+```
+
+Then, make sure that the generated data is created using:
+```shell
+make generate-data
+```
+
+Then to run a benchmark, use one of the benchmark Makefile targets prefixed with `bench-run-`:
+```shell
+make bench-run-tpch-sf1
+```
+Now the TPCH benchmark will be run twice, once on parquet files and once on a delta table.
+
+To create a plot from the results run:
+```shell
+make plot
+```
+
+## More options
+Specific benchmarks can be run from a suite using the `BENCHMARK_PATTERN` variable. For example to compare
+only Q01 from TPCH SF1, run:
+```shell
+BENCHMARK_PATTERN=q01.benchmark make bench-run-tpch-sf1
+```
+
+Also, we can run all local benchmarks using:
+```shell
+make  bench-run-all-local
+```
+Or all remote benchmarks using
+```shell
+make bench-run-all-remote
+```
