# How to run examples
2+
3+
First, clone repository.
4+
5+
Create `.env` file with linkedin credentials in the parent catalog (in the repository root) like this
6+
7+
```ini
8+
LINKEDIN_CLIENT_ID=111ClinetId111
9+
LINKEDIN_CLIENT_SECRET=222ClientSecret
10+
```
11+
12+
To get client and secret go to [LinkedIn Developers portal](https://developer.linkedin.com/) and create new app there.
13+
14+
After add to OAuth 2.0 Authorized Redirect URLs:
15+
```
16+
http://localhost:8901/
17+
```
18+
19+
Next, run PHP embedded server in the repository root:
20+
21+
```bash
22+
php -S localhost:8901 -t examples
23+
```
24+
25+
Navigate to http://localhost:8901/
