 ## Installation
 
-In order to install the package you need to **have installed in the system the
-pcsclite libraries**.
+1. **Node Native Modules build tools**
 
-In **macOS** and **Windows** you **don't have to install** anything.
+    Because this library uses Node Native Modules (C++ Addons),
+    which are automatically built (using [node-gyp](https://github.com/nodejs/node-gyp))
+    when installing via npm or yarn, you need to have installed **C/C++ compiler
+    toolchain and some other tools** depending on your OS.
+    
+    **Please refer to the [node-gyp > Installation](https://github.com/nodejs/node-gyp#installation)**
+    for the list of required tools depending on your OS and steps how to install them.
 
-> For example, in Debian/Ubuntu:
-> ```bash
-> apt-get install libpcsclite1 libpcsclite-dev
-> ```
-> To run any code you will also need to have installed the pcsc daemon:
-> ```bash
-> apt-get install pcscd
-> ```
+2. **PC/SC API in your OS**
 
-Once you have all needed libraries, you can install using npm:
+    On **macOS** and **Windows** you **don't have to install** anything,
+    **pcsclite API** is provided by the OS.
+    
+    On Linux/UNIX you'd probably need to install pcsclite library and deamon**.
 
-```bash
-npm install @pokusew/pcsclite --save
-```

+    > ```bash
+    > apt-get install pcscd
+    > ```
+
+3. Once you have all needed libraries, you can install node-pcsclite using npm:
+
+    ```bash
+    npm install @pokusew/pcsclite --save
+    ```
+    
+    or using Yarn:
+    
+    ```bash
+    yarn add @pokusew/pcsclite

 For Windows, I recommend you to use [AppVeyor](https://appveyor.com/).  
 For macOS and Linux build, there are plenty of services to choose from, for example [CircleCI](https://circleci.com/), [Travis CI](https://travis-ci.com/) [CodeShip](https://codeship.com/).
 
+### Are prebuilt binaries provided?
+
+No, because it brings more problems than it solves. The C++ code (Node Native Modules, C++ Addons) is built automatically during installation (using [node-gyp](https://github.com/nodejs/node-gyp)).
