+# Nodepy - A library for using nodejs commands and files in Python
+
+## License
+
+This program is distributed under the terms of the CC BY-NC-SA 2.0 license
+
+## Installation
+
+    wget https://github.com/thecookingsenpai/nodepy
+
+Now you can copy the jspyth.py file into your project directory and 
+
+    import jspyth
+
+And proceed to the usage as shown below
+
+## Usage
+
+### NOTE: This readme is WIP
+
+### NOTE: This program is in beta state
+
+Nodepy allows you to use nodejs commands and files in Python.
+
+You can either use it through:
+
+    cmd = jspyth.JSCommand(is_file="False", command=["console.log", ["hello world"], ["eventual", "libraries", "to", "include"]], real_time=True)
+    result = cmd.run()
+
+Or with a file:
+
+    cmd = jspyth.JSCommand(is_file="True", file="filename,js", real_time=True)
+    result = cmd.run()
+
+Where
+
+    real_time = True/False
+
+Allows you to see the output in real time.
+
+The parameters part of the command and the include libraries are optional and should be used based on the command provided.
+
+## Techical informations
+
+The whole library is a wrapper around subthreading and is designed to be blocking, meaning that the subthread will be executed and awaited by Python.
+
+The only prerequisite is having node installed and to npm install the needed libraries to include.
