-[![Build status](https://ci.appveyor.com/api/projects/status/ciq9vo4caq0wmxap/branch/develop?svg=true)](https://ci.appveyor.com/project/litjson/litjson/branch/develop)
+[![NuGet](https://img.shields.io/nuget/v/LitJson.svg)](https://www.nuget.org/packages/LitJson) [![MyGet](https://img.shields.io/myget/litjson/vpre/LitJson.svg?label=myget)](https://www.myget.org/gallery/litjson)
 
 A *.Net* library to handle conversions from and to JSON (JavaScript Object
 Notation) strings.
 
-[Project website][litjson].
+> _It's quick and lean, without external dependencies.
+> Just a few classes so easily embeddable in your own code or a very small assembly to ship with your code.
+> The code is highly portable, which in general makes it easy to adapt for new platforms._
 
 
-## Compiling
-
-See the files under the `build` directory.
-
-### Using GNU Make
+## Continuous integration
 
-Change directory to `build/make/` and run `make` from it. This tries to use
-the `gmcs` compiler by default. Feel free to open the `Makefile` and tweak
-it according to your needs.

-### Using other tools
 
-Currently, LitJSON doesn't have any other auxiliary files for compiling this
-library with other tools.
+## Compiling
 
-If you want to contribute your own solutions to compile it with tools like
-*NAnt* or *MSBuild*, that would be most appreciated. Please create those
-auxiliary files under the path `build/some-tool`. Thanks.
+Code can be compiled using .NET CLI or by launching the bootstrappers in the root of the repository.
 
-## Tests
+#### Windows
 
-This library comes with a set of unit tests using the [NUnit][nunit]
-framework.
+```powershell
+./build.ps1
+```
 
-If you have [pkg-config][pkg-config] in your system, and the *Mono* suite
-provides the `mono-nunit.pc` file, you can try running these tests by running
-`make test` from the `build/make` directory.
+#### Linux / OS X
 
-You can specify which `pkg-config` is invoked by passing a `PKG_CONFIG`
-variable to `make test`. This is useful when you have mutiple conflicting
-`pkg-config`s on your system and need to select the correct one (i.e. to
-avoid conflicts with Homebrew on Mac OSX).
+```console
+./build.sh
+```
 
-Example of running the tests on Mac OSX:
+#### Prerequisites
+
+The bootstrappers will (locally in repo)
+  
+  * Fetch and install .NET Core CLI / SDK version needed to compile LitJSON.
+  * Fetch and install Cake runner
+  * Execute build script with supplied target (`--target=[Target]`) or by default
+    1. Clean previous artifacts
+    1. Restore build dependencies from NuGet
+    1. Build
+    1. Run unit tests
+    1. Create NuGet package
+  
+#### Testing
 
-```bash
-# In litjson/ directory
-$ cd build/make
-$ make PKG_CONFIG=/Library/Frameworks/Mono.framework/Commands/pkg-config test
-```
+This library comes with a set of unit tests using the [NUnit][nunit]
+framework.
 
 ## Using LitJSON from an application
 
 #### Package manager
 
 ```PowerShell
-Install-Package LitJson -Version 0.9.0
+Install-Package LitJson -Version 0.10.0
 ```
 
 #### .NET CLI
 
 ```PowerShell
-dotnet add package LitJson --version 0.9.0
+dotnet add package LitJson --version 0.10.0
 ```
 
 #### Paket CLI
 
 ```PowerShell
-paket add LitJson --version 0.9.0
+paket add LitJson --version 0.10.0
 ```
 
-
 Alternatively, just copy the whole tree of files under `src/LitJSON` to your
 own project's source tree and integrate it with your development environment.
 
+#### Requirements
+
+LitJSON currently targets and supports
+* .NET Standard 2.0
+* .NET Standard 1.5
+* .NET Framework 4.5 and above
+* Mono 4.4.2 and above
+
+But the code is very portable and can even be compiled under SQLCLR, which [WCOMAB/SqlServerSlackAPI](https://github.com/WCOMAB/SqlServerSlackAPI) is an example of.
+
+#### Prereleases
+
+Each merge to develop is published to our NuGet feed on [MyGet](mygetgallery).
+
