+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).

+                        Dying Light is a 2015 survival horror video game developed by Techland and published by Warner Bros. Interactive Entertainment. The game's story follows undercover agent Kyle Crane who is sent to infiltrate a quarantine zone in a fictional Middle Eastern city called Harran. It features an enemy-infested, open world city with a dynamic day–night cycle, in which zombies are slow and clumsy during daytime and extremely aggressive at night. The gameplay is focused on weapons-based combat and parkour, allowing players to choose fight or flight when presented with dangers. The game features an asymmetrical multiplayer mode (originally set to be a pre-order bonus), and a four-player co-operative multiplayer mode.
+                    </p>
+                    <p>
+                        The development of the game began in early 2012, after the team completed the development of Dead Island. The game's parkour system emphasizes natural movement. To implement that, Techland had to abandon most of the story elements and construct them again from scratch. To create a story that would suit the taste of the American audience, the writing team collaborated with Dan Jolley. The story was inspired by both Heart of Darkness and The Plague. Announced in May 2013, it was released in January 2015 for Linux, PlayStation 4, Windows, and Xbox One. The game was planned to be released on PlayStation 3 and Xbox 360, but these versions were cancelled due to hardware limitations.

+                    <p>
+                        Dying Light is a survival horror video game played from a first-person perspective. The game is set in an open world environment called Harran; initially, an area named the Slums can be freely explored, later adding a second area, accessible via sewers, called Old Town. Players traverse this urban environment, which is overrun by zombies. There is an emphasis on parkour mechanics, which allow players to perform actions such as climbing ledges, leaping from edges, sliding, jumping between roofs and zip-lining. A grappling hook allows players to climb up buildings and quickly travel between places. As players explore the game's world, they can scavenge supplies and loot, which can be used to craft new weapons or sold to vendors. The player character can utilise his "survivor sense" to identify all nearby loot and use lock picks to open locked chests and locked vehicles. Players can also complete various side missions by accepting tasks issued by the non-playable characters in the game's safe zones. As players explore Harran, they can also pick up various collectibles such as notes and journals, and listen to voice mail recordings.
+                    </p>
+                    <p>
+                        Dying Light contains a dynamic day–night cycle. During the day, players can set traps, save random survivors, and make their way to airdrops. The infected are slow, apathetic, and easily visible and they can be easily avoided. Players can use environmental traps, such as spikes, electrified fences, and gas tanks, to kill the infected. At night, the infected transform to become much more dangerous. Without daylight, the senses of the infected become more acute and accurate. They can sprint after the player character, inflict more damage, and gain the ability to jump and climb buildings. For players to avoid contact, they need to use their "survivor sense" to locate and avoid the infected. If the player character is spotted, they can use distractions and traps to reduce the number of infected. Players' main defence against the infected is ultraviolet light, which slows their movement. At safehouses, players can adjust the time of day, skipping night altogether if the player does not feel ready.
