-## Dev Server
-
-To use dev server, you must have an SSL certificate since browsers enforce *https* for webcam access
-
-You can use a provided ones self-signed certificate or configure your own
-
-Self-signed test certificate was generated using:
-
-```shell
-openssl req -x509 -newkey rsa:4096 -nodes -keyout https.key -out https.crt -days 365 -subj "/C=US/ST=Florida/L=Miami/O=@vladmandic"
-```
-
-If you want to use your own certificate, edit `server/dev.js`:
-
-```js
-const options = {
- key: fs.readFileSync('server/https.key'),
- cert: fs.readFileSync('server/https.crt'),
-};
-```
-
-Once SSL certificates have been provided (defalt test certificate or your own), simply run
-
-```shell
-npm run dev
-```
-
-On first start, it will install all development dependencies required to rebuild `Human` library
-Dev version of the library runs without code minification for easier debugging while production version is fully minified
-
-By default, secure http2 web server will run on port `10031` and unsecure http server will run on port `10030` which is configurable in `server/dev.js:options.port`
