Creating a Contest on HackerRank is an easy process which is divided in 2 steps.

Create a Challenge
Create a Contest.

#1. Create a Challenge
##Opening create challenge window


Go to the top right corner, click your username and select Administration
or Click = > Manage Challenges


Click Manage Challenges Tab
or Click = > Manage Challenges


Click the green button "New Challenge" in the top right section.


##Making a New Challenge

Now we have the challenge creator window.
Which has the following sections
####Challenge Name
This is the name that will appear for the challenge.

Enter the challenge name, for the challenge you want to create.
####Description
A brief intro to the problem statement. Where you briefly define the what the challenge is. HackerRank recommends to write something in this section.
####Problem Statement
Here the actual problem statement is written. Make sure you write in markdown Markdown Editor

A good problem statement contains

Description of the problem
Any further Clarifications or Notes, that you feel a person may overlook, or wrongly assume. (Optional)
Input format
Output format
Constraints
Sample Input
Sample Output
Explanation of the sample (minimum 2)

Click Save Once you finish writing the problem statement. This will enable more configuration options that we'll see now.
##Tips on Markdown syntax:

Use Capital Letters to denote Variable names.
Use double space at the end of line to give line breaks.
Use **text** for Bold effect
Use _text_ for Italics effect
Use Italics for all Variable names and things to highlight.
Use back ticks (`) for something that has to be exactly printed in output. E.g. Print YES or NO.
Use 4 spaces before each line in Sample Input and Sample Output. This acts as a <pre> tag in HTML.
Use &le; &ge; for less than equal or greater than equal in constraints.
Use <sub> and <sup> For subscript and super script. Avoid ^ for super script.
Don't forget to escape the wild characters *, | , _ etc.

A sample problem statement goes like this
This is an introductory challenge. The purpose of this challenge is to give you a working I/O template in your preferred language. It includes scanning 2 integers from `STDIN`, calling a function, returning a value, and printing it to `STDOUT`.    

Your task is to scan two numbers from `STDIN`, and print the sum A+B on `STDOUT`. 

**Note**: The code has been saved in a template, which you can submit if you want. 

**Input Format**  
Given _A_ and _B_ on two different lines.  

**Output Format**  
An integer that denotes Sum _(A + B)_ 

**Constraints**  
1 &le; _A_, _B_ &le; 1000

**Sample Input**

    2
    3

**Sample Output**

    5


##Tips on LaTeX syntax

Latex is available on HackerRank challenge editor and can be used by wrapping the text with $\text{Hello World!}$ for inline latex and $$\text{Hello World!}$$ for new line.
All the general latex tags are applicable, some examples below can be tried on HackerRank editor. You can find any latex guide on google and it'll work.

%Determinants  
$$
  \left| {\begin{array}{cc|c|c}
   A_{1,1} & A_{1,2} & \cdots & A_{1,N}\\\
   A_{2,1} & A_{2,2} & \cdots & A_{2,N} \\\
   \vdots & \vdots & \ddots & \vdots \\\
   A_{M,1} & A_{M,2} & \cdots & A_{M,N} \\\
  \end{array} } \right |
$$


% System of Equations 
$$\begin{align*}
g'(E) &= \sum_{k=1}^E g\left(\left\lfloor E/k \right\rfloor\right) \\\
g'(E) &= \sum_{k=1}^E \sum_{i=1}^{\lfloor E/k \rfloor} \nabla g(i) \\\
g'(E) &= \sum_{k\cdot i \le E} \nabla g(i)
\end{align*}$$  


Configuring a Challenge

###Test Cases

Click the tab test cases and for each test cases manually fill up input and output fields or upload input/output files for each test case. Give a score to your test case and save.
Or You can create a zip locally containing two folders input and output and having the files named as input00.txt , output00.txt and so on. And upload the zip.
Add at least 10-15 test cases to evaluate a problem.

Make sure you write 2-3 very simple(few lines) test cases and tick the sample checkbox ahead of them. These sample cases run when the user clicks Compile and Test. These have 0 or very low score compared to other test cases.
Make sure the sample test case given in the statement is added in the testcases and marked as sample.
Tip:- Add variety of test cases, few very basic and rest of them of tougher difficulty. Use weightage wisely
Click Save and move on to Languages
###Language

Here you can

Enable/Disable a language.
Set Time Limit.
Set Memory Limit.
Set Template

Note If you are not sure of what you are doing Please do not change the default values.
A quick guide to problem setting will help here
Click Save
Custom Checker

This is an advanced feature and is used only when the output returned from the code is to be further processed instead of plain matching against the expected output.
HackerRank recommends using Python for Custom Checker. A default template/guide for custom checker can be availed on request by sending an email to hackers [at] hackerrank [dot] com
###Flags
These are some checks which you can do once the challenge is ready.


Solved Score.
For 1 player game and challenges with custom checkers, this threshold will be used to determine solved or not. This flag is useful for various of statistics although it will not affect any score or leaderboard.


Precision Check
For 1 float per line output you can enable a precision check. A value of 0.01 would mean +/- 0.01 error tolerance.


Disable Compile and Test
Disables the Compile and Test button in the challenge.


Disable Custom Testcase
Disables the custom testcase window for users to try their own inputs.


Disable Submission Processing

Disables the real time submission processing. (Submissions then need to be processed at the end of contest.)


Disable Submission
Disables the submission on Challenge


Public Testcase
Test Case become public once the contest is over.


Public Solution
One can access all solutions of other participants from the Leaderboard once the contest is over.


Restricted Forum
Only the admins and staff can post on forums.


Click Save and your problem is created.
which can be accessed from Manage Contest
###Editorial

Use this field to write the editorial and this will be enabled when the contest is over.

Weight is the score of the problem

Binary enables binary scoring, by default users get partial scoring depending on the number of test cases they clear and the weighted average of the test cases.

Dynamic This enables the scoring to be based on number of summations
