+# Random Names Generator
+
+## A simple python script to generate some random names.
+
+### There are two csv files for 'First Name' and 'Last Name' in text 'CSV_Database_Of_First_And_Last_Names' taken from [here](http://www.quietaffiliate.com/free-first-name-and-last-name-databases-csv-and-sql/)
+
+# Usage
+### Step 1
+Fork this Repo and Clone it to your local machine.
+```sh
+$ git clone https://github.com/YOUR_USERNAME/Random_Names_Generator.git
+$ cd Random_Names_Generator
+```
+### Step 2
+To run the python3 program
+```sh
+$ python3 Random_Name_Generator.py
+```
+The above only returns only one name.
+
+
+Add number of names if more than one name is required.
+```sh
+$ python3 Random_Name_Generator.py 5
+```
+---
+Tip:- 
+In Linux Machines you can save the files as text using output redirection
+```sh
+$ python3 Random_Name_Generator.py 10 >> Random_Names_Generator.txt
+```
