+# Windows
+
+## Install Natively
+
+### [Install Chocolatey](https://chocolatey.org/install#installing-chocolatey) (optional)
+
+### [Install git](https://git-scm.com/)
+[Download](https://git-scm.com/download/)
+or
+```bat
+choco install git
+```
+
+### [Install Ruby](https://www.ruby-lang.org/)
+[Download](https://rubyinstaller.org/downloads/)
+or
+```bat
+choco install ruby
+```
+
+### [Install nim](https://nim-lang.org/)
+1. [Download](https://nim-lang.org/install_windows.html)
+2. Add nim to PATH:
+```%USERPROFILE%\.nimble\bin```
+or 
+where your nim is installed (you can check it when installs).
+
+### [Install neverwinter_utils.nim](https://github.com/niv/neverwinter.nim)
+```bat
+nimble install neverwinter
+```
+
+### [Install nwnsc](https://gitlab.com/glorwinger/nwnsc)
+1. [Download](https://neverwintervault.org/project/nwnee/other/tool/nwnsc-nwn-enhanced-edition-script-compiler)
+2. Extract in some folder under your watch like ```%USERPROFILE%\bin```
+3. Add nwnsc.exe folder to PATH (optional)
+
+### Install nwn-devbase
+Navigate to where you want the nwn-devbase sources located on your system. `%USERPROFILE%\src\` is a good choice.
+```bat
+git clone https://github.com/jakkn/nwn-devbase.git
+cd nwn-devbase
+gem install bundler
+bundle install
+```
+
+## First usage
+
+### Without PATH
+```bat
+mkdir my-project && cd my-project
+git init
+ruby path-to-nwn-devbase/build.rb init
+cp path-to-my-module.mod server/modules/
+ruby path-to-nwn-devbase/build.rb extract
+git add -A && git commit -m "Initial commit"
+```
+
+### With PATH
+Create if it does not exist, and add ```%USERPROFILE%\bin``` to PATH.
+Execute in PowerShell:
+```posh
+cd path-to-nwn-devbase
+cmd /c MKLINK "$env:USERPROFILE\bin\nwn-build.rb" "$(pwd)\build.rb"
+```
+And then:
+```bat
+mkdir my-project && cd my-project
+git init
+nwn-build init
+cp path-to-my-module.mod server/modules/
+nwn-build extract
+git add -A && git commit -m "Initial commit"
+```
+
+## Pack and compile
+For nss compilation to work, it may be necessary to set some PATHs if the defaults do not match with your system environment. Either specify the paths at run time with
+
+```bat
+NWN_USERDIR="%programfiles(x86)%/Steam/steamapps/common/Neverwinter Nights" NSS_COMPILER="%USERPROFILE%/bin/nwnsc" nwn-build compile
+```
+or set them permanently in system environment variables. Placing the compiler in a folder on PATH, like `%USERPROFILE%/bin` should also work.
+
+#### NSS compiler
+`build.rb` looks for the _NSS_COMPILER_ environment variable, and defaults to `nwnsc` if that does not exist. Either add the compiler to your PATH, or create the NSS_COMPILER environment variable that points to the nss compiler of your choice.
+
+#### NWN install dir
+The compiler run arguments specify game resources located in _NWN_USERDIR_ environment variable. This is needed to locate `nwscript.nss` and base game includes.
+
+#### PACK
+First, close the Aurora Toolset, then run:
+```bat
+nwn-build pack
+```
+
+## Toolset
+To locate your .mod packed file in some other folder that is required by the Aurora toolset you can create a symbolic link with the following command in Power Shell:
+```posh
+cmd /c MKLINK "NWN_USERDIR\modules\my-module.mod" "PATH_TO_REPO\server\modules\my-module.mod"
+```
+Replace NWN_USERDIR with the path to where your local NWN client reads modules from (%USERPROFILE%\Documents\Neverwinter Nights\modules), and PATH_TO_REPO with the path to the repository of a given project.
