1 | ## Lesson-9
2 |
3 | Creating our firebase database and adding the firebase library into our code. Add google sign in and authentication into our application.
4 |
5 | # How to fork and clone
6 |
7 | One quick note about cloning this project. If you wish to make commits and push the code up after cloning this repo, you should fork the project first. In order to own your own copy of this repository, you have to fork it so you get your own copy on your own profile!
8 |
9 | You can see the fork button in the top right corner of every GitHub project; click it and a copy of the project will be added to your GitHub profile under the same name as the original project.
10 |
11 | 
12 |
13 | After forking the project, simply clone it the way you would from the new forked project in your own GitHub repository and you can commit and push to it freely!
14 |
15 |
16 | # After you fork and clone:
17 |
18 | ## Install dependencies
19 |
20 | In your terminal after you clone your project down, remember to run either `yarn` or `npm install` to build all the dependencies in the project.
21 |
22 | ## Set your firebase config
23 |
24 | Remember to replace the `config` variable in your `firebase.utils.js` with your own config object from the firebase dashboard! Navigate to the project settings and scroll down to the config code. Copy the object in the code and replace the variable in your cloned code.
