 This project uses [Bun](https://bun.sh/) to benchmark various AlaSQL versions across a range of SQL operations, from simple queries to complex aggregations. It uses npm aliasing to install multiple versions of AlaSQL simultaneously.

-- npm or bun package manager

 ## Installation
 
 ```bash

+cd historical-performance
+
 # Install dependencies
-npm install
-# or
 bun install
+# or

 ## Usage
 
-### Run Full Benchmark
+### Benchmark A - Custom Implementation
+
+Custom benchmark with detailed console output, summary tables, and markdown results.
 
 ```bash
-bun run benchmark
+yarn bench-a
 ```
 
-### Run Quick Benchmark (fewer iterations)
-
+With custom cycles:
 ```bash
-bun run benchmark:quick
+yarn bench-a --cycles 10
 ```
 
-### Run Directly with Bun
+### Benchmark B - Bun Native
+
+Uses Bun's native `bench`, `group`, and `run` functions for performance measurement.
 
 ```bash
-bun run benchmark.ts
-bun run benchmark.ts --quick
+yarn bench-b
 ```
 
 ## How It Works
 
+### Version Management
+
 The project uses npm aliasing to install multiple AlaSQL versions:
 
 ```json
 {
   "devDependencies": {
     "alasql-0.3.10": "npm:alasql@0.3.10",
-    "alasql-0.4.12": "npm:alasql@0.4.12",
     "alasql-4.10.1": "npm:alasql@4.10.1"
-    // ... 64 versions total
   }
 }
 ```
 
-Each version can then be imported separately:
+### NEXT Version
 
-```typescript
-import alasql0310 from 'alasql-0.3.10';
-import alasql0412 from 'alasql-0.4.12';
-import alasql4101 from 'alasql-4.10.1';
-// ... etc
-```
+The NEXT version is managed as a git submodule pointing to the AlaSQL develop branch. The `build-next.sh` script handles:
 
-## Sample Output
+1. Updating the submodule to latest
+2. Installing dependencies
+3. Building the distribution
 
-The benchmark produces formatted output showing performance metrics for each version (actual results will vary based on your machine):
+## Sample Output (Benchmark A)
