+# TLS Certificates
+
+When working locally, its important to consider the end-user of your software. To mimic this as closely as possible, you will need to setup a local TLS certificate. Luckily, doing so is pretty easy with [mkcert](https://github.com/FiloSottile/mkcert).
+
+## Getting Started
+To begin, start by [installing on your system](https://github.com/FiloSottile/mkcert#installation).
+
+Once installed, we'll quickly generate our local CA.
+
+```bash
+mkcert -install
+```
+
+Next, we'll generate a certificate and put it in the right directory for Mage2Docker.
+
+```bash
+mkcert -key-file magento2.test.key -cert-file magento2.test.pem magento2.test
+mv magento2.test.key nginx/certs/magento2.test.key && mv magento2.test.pem nginx/certs/magento2.test.pem
+```
+
+## Enabling Local Cert Mounting with Mage2Docker
+Now, simply append the `docker-compose.TLS.yml` path to your `.env` file and bring your containers up `docker-compose up`.
+
+```
+COMPOSE_FILE=docker-compose.yml:...:docker-compose.TLS.yml
+```
+
+At this point, you should have a working TLS cert covering the `magento2.test` domain!
