 ## Install via NPM
-Make sure you have the appropriate dependencies installed and configured for your platform. You can find installation instructions for the dependencies for some common platforms [in this page][depsinstall].
 
 ```
 npm install bcrypt
 ```
 ***Note:*** OS X users using Xcode 4.3.1 or above may need to run the following command in their terminal prior to installing if errors occur regarding xcodebuild: ```sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer```

+Only the current stable and the supported LTS releases are actively tested against. Please note that there may be an interval between the release of the module and the availabilty of the compiled modules.
+
+Currently, we have pre-built binaries that support the following platforms:
+
+1. Windows x32 and x64
+2. Linux x64 (GlibC targets only). Pre-built binaries for MUSL targets such as Apline Linux are not available.
