-# cs4241-FinalProject
-
-For your final project, you'll implement a course project that exhibits your mastery of the course materials. 
-Similar to A4, this project gives you an opportunity to be creative and to pursue individual research and learning.
-
-## General description
-
-Your project should consist of a complete Web application, exhibiting facets of the three main sections of the course material:
-
-- Static Web page content and design. You should have a project that is accessible, easily navigable, and features significant content.
-- Dynamic behavior implemented with JavaScript.
-- Server-side programming *using Node.js*. Typically this will take the form of some sort of persistent data, authentication, and possibly server-side computation.
-
-Additionally, you should incorporate features that you independently research, design, and implement for your project.
-
-## Project ideation
-
-Excellent projects serve someone/some group; for this assignment you need to define your users and stakeholders. I encourage you to identify projects that will have impact, either artistically, politically, or in terms of productivity. Consider creating something useful for a cause or hobby you care about.
-
-## Logistics
-
-### Team size
-Students are encouraged to work in teams of 2-5 students for the project. This will allow you to build a good project without expending an excessive amount of effort. While I would expect a team of four or five students to produce a project with more features, I expect a every team's work to exhibit all of the required facets described above.
-
-### Deliverables
-
-__Proposal:__ 
-Provide an outline of your project direction and the names of the team members. 
-The outline should have enough detail so that staff can determine if it meets the minimum expectations, or if it goes too far to be reasonable by the deadline.
-This file must be named proposal.md so we can find it.
-Submit a PR to turn it in by Monday, September 30th, before class
-
-There are no other scheduled checkpoints for your project. 
-You must be done in time to present before the final project demo day (October 10th). 
-
-#### Turning in Your Outline / Project
-
-**NOTE: code is due before the project presentation day due to the end of term / grading schedule constraints**
-Submit a second PR on the final project repo to turn in your app and code.
-
-Deploy your app, in the form of a webpage, to Glitch/Heroku/Digital Ocean or some other service.
-Folks on the same team do not need to post the same webpage, but must instead clearly state who is on the team in their proposal.
-
-The README for your second pull request doesn’t need to be a formal report, but it should contain:
-
-1. A brief description of what you created, and a link to the project itself.
-2. Any additional instructions that might be needed to fully use your project (login information etc.)
-3. An outline of the technologies you used and how you used them.
-4. What challenges you faced in completing the project.
-5. What each group member was responsible for designing / developing.
-
-Think of 1,3, and 4 in particular in a similar vein to the design / tech achievements for A1—A4… make a case for why what you did was challenging and why your implementation deserves a grade of 100%.
-
-## Final Presentation
-
-Presentations will occur during the final day of class in *Riley Commons*.
-
-## FAQs
-
-- **Can I use XYZ framework?** You can use any web-based frameworks or tools available, but for your server programming you need to use node.js.
+https://glitch.com/~fp-jamevor-tpatterson
+Justin Amevor
+Tyrone Patterson
+Doughboyz Catering
+
+The goal of this application is for customers to order foods form the app. Customers can place an order and also use the 
+visualizer to see what there order would look like with different condiments. 
+
+To fully use the site you should login by first signing up by making a username and password.
+
+**Important:** The account linked to the text confirmation portion of the application only has 7 more texts it is able to send before the account locks
+and it won't be able to send them anymore. So use them wisely.
+
+Technologies Used:
+Three.js-Justin
+javascript-Tyrone 
+Jquerry/DataTables-Justin
+Bootstrap-Justin
+lowDB-Tyrone 
+TextMagic Rest Client-Tyrone
+NodeMailer-Tyrone
+
+The entire project was somewhat challenging. Justin struggled with backend development and Tyronne struggled with front end development.
+Luckily we helped each other with our weak areas but getting data to store in the database was especially challenging.  
+
+This project deserves a 100 because we not only spent hours working on the implmentation of the technologies, we asked various 
+stakeholders features that they would like to have in a ordering application. From their feedback we established using Twello 
+to send confirmations to users phones or emails would be a desirable feature. This project also made the application a bit smoother
+adding more Bootstrap, cleaning up backend code, and adding more funcinality to the ordering page. This application can fully be used
+to take orders from customers by storing them in a succinct database. The work and effort shown in this project is over 20 hours of 
+programming in the last weeks.
