+`traceroute` command is a command in Linux that prints the route a network packet takes from its source (e.g. your computer) to the destination host (e.g., roadmap.sh). It is quite valuable in investigating slow network connections as it can help us spot the slow leg of the network packet journey through the internet.

\ No newline at end of file
+# Promises
+
+A promise is commonly defined as a proxy for a value that will eventually become available
+Asynchronous functions use promise behind the scens, so understanding how promises work is fundamental to understanding how "async" and "await" works.
+Once a promise has been called, it will start in a pending state. This means that the calling function continues executing, while the promise is pending until it resolves, giving the calling function whatever data was being requested.
+
+Creating a Promise:
+The Promise API exposes a Promise constructor, which you initialize using newPromise().
+
+Using resolve() and reject(), we can communicate back to the caller what the resulting Promise state was, and what to do with it.

+# Contribution
+
+First of all thank you for considering to contribute. Please look at the details below:
+
+* [New Roadmaps](#new-roadmaps)
+* [Existing Roadmaps](#existing-roadmaps)
+* [Adding Content](#adding-content)
+* [Guidelines](#guidelines)
+
+## New Roadmaps
+
+For new roadmaps, submit a roadmap by providing [a textual roadmap similar to this roadmap](https://gist.github.com/kamranahmedse/98758d2c73799b3a6ce17385e4c548a5) in an issue.
+
+## Existing Roadmaps
+
+For the existing roadmaps, please follow the details listed for the nature of contribution:
+
+* **Fixing Typos** — Make your changes in the [roadmap JSON file](https://github.com/kamranahmedse/developer-roadmap/tree/master/public/project)
+* **Adding or Removing Nodes** — Please open an issue with your suggestion.
+
+**Note:** Please note that our goal is not to have the biggest list of items. Our goal is to list items or skills most relevant today.
+
+## Adding Content
+
+Adding Content to Nodes — Add your content in [the content directory inside the relevant roadmap](https://github.com/kamranahmedse/developer-roadmap/tree/master/content/roadmaps).
+
+Please note that the markdown has a specific format. Please follow the sample format for markdown as given here.
+
+* Title of the file to represent the node item.
+* Add a brief summary describing the roadmap node (preferably less than 200 characters)
+* Use `ResourceGroupTitle` tag for the resources heading
+
+ ```html
+ Free Content
+ ```
+
+* Use `BadgeLink` tag for the resource links with below guidelines
+
+ ```html

+ React Website

+ Understanding React's UI Rendering Process

+
+## Guidelines
+
+- Adding everything available out there is not the goal!
+ The roadmaps represent the skillset most valuable today, i.e., if you were to enter any of the listed fields today, what would you learn?! There might be things that are of-course being used today but prioritize the things that are most in demand today, e.g., agreed that lots of people are using angular.js today but you wouldn't want to learn that instead of React, Angular, or Vue. Use your critical thinking to filter out non-essential stuff. Give honest arguments for why the resource should be included.
+- Do not add things you have not evaluated personally!
+ Use your critical thinking to filter out non-essential stuff. Give honest arguments for why the resource should be included. Have you read this book? Can you give a short article?
+- One item per Pull Request
+ There may be a discussion related to an item you want to add. Adding just a single item per pull request makes it much easier for everyone involved.
+- Write meaningful commit messages
+- Look at the existing issues/pull requests before opening new ones

-## The Goal
-
-* For the roadmaps, we encourage you to discuss and contribute by adding new roadmaps. For the existing ones, please note that our goal is not to have the biggest list of items. Our goal is to list items or skills most relevant today.
-* For the resources, please note that they are *highly opinionated* and *curated*. Your opinion on the value of any resource may not match the opinion of the curator.
