 # [hMSBuild](https://github.com/3F/hMSBuild)
 
-A lightweight tool (~19 Kb compiled text-based embeddable batch-scripts that does not require powershell and dotnet-cli) - an easy helper for searching of available MSBuild tools. Supports tools from VS2017+ (does not require additional vswhere.exe [[?](https://github.com/Microsoft/vswhere/issues/41)]), VS2015 or less, and other versions from .NET Framework.

 ## Why hMSBuild ?
 
 *because you need simple access to msbuild tools and more...* 
 
-Based on **GetNuTool core** https://github.com/3F/GetNuTool, and initially it was a more simplified msbuild-helper as part of this tool. But with latest changes from MS we extracted this into new project for more support of all this.

+
+* Initially, it was part of this tool like a small msbuild-helper. Then, it has been extracted into the new project after major changes from MS for their products. Now we have more support of all this.
+
+Today's [hMSBuild](https://github.com/3F/hMSBuild) provides flexible way to access to msbuild tools for any type of your projects. Just specify what you need in different environments. Look at *#Algorithm of searching* below.

 ### Features
 
-**1 batch file and no anything else** for your happy build. 
+Just a **single batch file** and no more for your happy build. 
+
+Combine this with your other available scripts or just type `hMSBuild {arguments to original msbuild}` and have fun.
 
-Combine with your other available scripts or just type `hMSBuild <args to msbuild.exe>` and have fun. Start with `hMSBuild -h`
+Start with `hMSBuild -h`
 
 ### What supports ?
 
 * Versions from VS2017+ 
     * Full support even if you still have no any [local `vswhere.exe`](https://github.com/Microsoft/vswhere/issues/41) [[?](https://github.com/Microsoft/vswhere/issues/41)]
 
-* Versions from VS2015, VS2013, .NET Framework

+### Algorithm of searching
+
+**v2.0+**
+
+* Versions: 
+  * VS2017+ ➟ VS2015, VS2013, ... ➟ .netfx
+* Architectures (configure via `-notamd64` key): 
+  * x64 ➟ x32
+* Priorities (configure via `-vsw-priority` and `-stable` keys). *Specific workload components in more priority than pre-release products. See [Issue #8](https://github.com/3F/hMSBuild/issues/8)*
+
+  1. Stable releases with selected workload components (C++ etc) ➟ Same via beta releases if allowed.
+  1. Stable releases with any available components ➟ Same via beta releases if allowed.

 ## Usage
 
-Usage is same as it would be same for msbuild. But you also have additional keys to access to GetNuTool core and to settings of hMSBuild:
