-The Assingment is divided into 2 sets - Tasks and Features.
-Candidates are free to implement any single or multiple task.
-Features are optional and hence are not mandatory, but implementing it would increaes their weighted in interview.
-
-Candidates must not use any 3rd party library. Assingment will not be evaluated if 3rd party library is used
-
-
-1. Go to https://exchangeratesapi.io/
-This website will provide you data regarding the exchange rate for various curriencies.
-You have to use the REST End point exposed by https://exchangeratesapi.io/ to get the required data for the assingment.
-Your task is to
-  - [T-1] Plot the graph of INR  exchange rate against USD from 1 Jan 2019 to 31 Jan 2019.
-  - [T-2] Plot the graph of INR and GBP exchange rate against USD from 1 Jan 2019 to 31 Jan 2019.
-  - [T-3] Plot the graph of INR and GBP exchange rate against USD from 1 Jan 2019 to 31 Jan 2019 and also indicate current rate for INR and GBP on graph itself.
-
-  Nice to have feature
-  - [F-1] - Make date range dyanamic so that we can select our own date range
-  - [F-2] - Make selection of currency symbol dyanamic, so we can choose any currency and graph should update accordingly.
-
-
-  - You can chosse any graph style as per your choice but it should represent data in meaningfull way.
-
-
-  [ Find the video link which describe the below propcess:  ]
-  1. You must fork this empty git repository.
-     - Github link : https://github.com/winsoft-technologies/2020-interns
-  2. Once you forked it they you clone their own copy on your machines and can start coding.
-  3. You have to do periodic commits, so that we can track the code development process.
-  4. Once you are done, you have to generate the pull request into the main github repo from where you have cloned. (https://github.com/winsoft-technologies/2020-interns)
-  5. While generating pull request make sure your title discribe what you have done....
-     For Example:
-        A candidate who have implemet only task 1 should have title
-        [T - 1] - <some short discription>
-
-        A candidate who have implemet only task 1 and 2 should have title
-        [T - 1 - 2] - <some short discription>
-
-        A candidate who have implemet only task 1 and Feature 1 should have title
-        [T - 1 - F - 1] - <some short discription>
-
-        A candidate who have implemet only task 1,2 and Feature 1,2 should have title
-        [T - 1 - 2 - F - 1-2] - <some short discription>
-  6. Only first "n" pull requested will be evaluated.
-  7. If any copy is found then both candidates will be disqulified.
-  8. Candidate attempting more task and feature will obiviously take more time than the one implemting single task,
-     hence top "n" will be shortlistied accordingly, so dont be in hurry if you fell confident try implementing more Task and Feature to make your candidature more solid.
+### ROUND 1: ASSIGNMENT (SUBMISSON IN GIT HUB)
+
+`Deadline of submission of assignment = Wednesday, 22nd July 2020 @ 12 Noon`
+
+ - No submission after 22nd July 20; 12 Noon will be considered
+ - Higher weightage will be given to candidates with early submission {the earliest, the better}
+
+#### Please find below the path to proceed for 1st ROUND of evaluation –
+
+- This is an assignment submission round.
+- The Assignment is divided into 2 sets - Tasks and Features.
+- Candidates are free to implement any single or multiple tasks.
+- Features are optional and hence are not mandatory, but implementing it would increase their weighted in
+an interview.
+- Candidate attempting more tasks and features will obviously take more time than the one implementing
+single task, hence the candidates will be shortlisted accordingly, so don't be in a hurry if you feel confident try
+implementing more Task and Feature to make your candidature more solid.
+- If any copy is found then both candidates will be *disqualified*.
+
+
+`IMPORTANT NOTE-``
+
+**Candidates must not use any 3rd party library. The assignment will not be evaluated if the 3rd party library is used**
+
+`PART 1 - ASSIGNMENT DETAILS`
+- Draw a graph which represents the performance of currencies over a period of time
+- The data to plot the graph can be found in `data.json` file in the Github repository
+`Github link : https://github.com/winsoft-technologies/2020-interns`
+
+
+
+##### Your work is to submit any one or all of the below mentioned tasks
+
+`Applicable to [T1], [T2], and [T3]: Historic data can be found using data.json file`
+-  `[T-1]` Plot the graph of INR exchange rate against EUR from 1 Jan 2019 to 31 Jan 2019
+- `[T-2]` Plot the graph of INR and GBP exchange rate against EUR from 1 Jan 2019 to 31 Jan 2019.
+- `[T-3]` Plot the graph of INR and GBP exchange rate against EUR from 1 Jan 2019 to 31 Jan 2019 and also indicate
+the current rate for INR and GBP on the graph itself. (You will get latest rates in the latest-rates.json file)
+- `[T-4]` Replace the data.json file with the data from the Rest EndPoint exposed at https://exchangeratesapi.io/
+ > - This website will provide you data regarding the exchange rate for various currencies.
+
+ > - You have to use the REST Endpoint exposed by https://exchangeratesapi.io/ to get the required data for the
+Assignment.
+
+
+#### Nice to have features-
+- `[F-1]` - Make date range dynamic so that we can select our own date range
+- `[F-2]` - Make selection of currency symbol dynamic, so we can choose any currency and the graph should
+update accordingly.You can choose any graph style as per your choice but it should represent data in a
+meaningful way.
+
+
+### PART 2- HOW TO DO IT?

+
+STEPS TO FOLLOW-
+1. You must fork this empty Git repository
+
+> Github link: https://github.com/winsoft-technologies/2020-interns
+
+2. Once you forked it then you have to clone your own copy on your machines and can start coding.
+3. You have to do periodic commits (no bulk commits), so that we can track the code development process.
+4. Once you are done, you have to generate the pull request into the main GitHub repo from where you have
+cloned. (https://github.com/winsoft-technologies/2020-interns)
+5. While generating pull requests make sure your title describes what you have done....
+
+ `For Example:`
+
+ - A candidate who has implemented only task 1 should have the title
+
+    `[T - 1] - <some short discription>`
+
+ - A candidate who has implemented only task 1 and 2 should have the title
+
+    `[T - 1 - 2] - <some short discription>`
+
+ - A candidate who has implemented only task 1 and Feature 1 should have the title
+
+    `[T - 1 - F - 1] - <some short discription>`
+
+ - A candidate who has implemented only task 1,2 and Feature 1,2 should have the title
+
+    `[T - 1 - 2 - F - 1-2] - <some short discription>`
+
+#### NOTES:
+1. Candidate sending first will get higher preference
+    > Candidate attempting more tasks and features will obviously take more time than the one implementing single task, hence the candidates will be shortlisted accordingly, so don't be in a hurry if you feel confident try implementing more Task and Feature to make your candidature more solid.
+
+2. Don't commit in bulk, do small commit so that we can see the code development process.
+
+3. `IMPORTANT`
+
+  - In pull request comment add your contact details, so that we can easily reach you
+> mention you full name, college name, email id and mobile number.
