+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <kamranahmed.se@gmail.com>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+

But how does the client know that this is the point where first response download completes and the content for next response starts, you may ask! Well, to solve this, there must be `Content-Length` header present which clients can use to identify where the response ends and it can start waiting for the next response.

Well in that case, you really can't benefit from persistent connections, could you?! In order to solve this `HTTP/1.1` introduced chunked encoding. In such cases server may omit content-Length in favor of chunked encoding (more to it in a moment). However, if none of them are available, then the connection must be closed at the end of request.

+# Threads and Concurrency
+
+A thread is an execution context in which the instructions to the CPU can be scheduled and executed independently of the parent process. Concurrency is the concept of multiple threads in a shared memory space being computed simultaneously (or intermittently executed in succession to provide that illusion). Concurrency allows multiple processes to execute at once and can apply to programming languages as well as operating systems.

-# Become a Frontend Developer
-Before I go ahead and list down the resources, please know that the roadmap and the list below is exhaustive and you don't need to know it all from the get go. For frontend development, all you need to get started with is learn some basic HTML, CSS and JavaScript and start working on projects; everything else you will learn along the way. 
-
-## Internet and how it works?
-
-Get the basic understanding of internet, browsers, networks and other relevant knowledge.

-
-## Learn HTML
-HTML provides the skeleton of a webpage. Learn the basics of HTML; learn the basic tags, learn how to write semantic HTML, understand basic SEO, learn how to divide your pages into sections that will help you style them. 
-
-Please know that I have put multiple links for each resource. While you may pick something new while going through each, you don't need to go through all of them - if you feel like you have understood the concepts and are just repeating what you learnt, you may skip the resource and move to exercises section.

-
-## Style your pages with CSS
-With the help of HTML, you create structure for your pages. CSS allows you to style your pages and make them pretty. If you take the analogy of human body, the skeleton would be the HTML, skin would be the CSS and muscles that help us move would be JavaScript - we will learn more about JavaScript in the coming sections.

-## Version Control Systems and Git
-
-Version control systems allow you to track changes to your codebase/files over time. They allow you to go back to some previous version of the codebase without any issues. Also, they help in collaborating with people working on the same code – if you’ve ever collaborated with other people on a project, you might already know the frustration of copying and merging the changes from someone else into your codebase; version control systems allow you to get rid of this issue.
-
-In this section, you will learn what version control systems are and understand how to use Git which is the de facto VCS.

+# Version Control Systems
+
+Version control systems allow you to track changes to your codebase/files over time. They allow you to go back to some previous version of the codebase without any issues. Also, they help in collaborating with people working on the same code – if you’ve ever collaborated with other people on a project, you might already know the frustration of copying and merging the changes from someone else into your codebase; version control systems allow you to get rid of this issue.
