+### Generate a self-signed certificate
+
+In order to run this repo in local development mode, two files must be added to the repo's root directory. The following set of commands apply to a macOS system. However, if mkcert is installed by another package manager, this can be run on any flavor of *nix.
+
+```bash
+cd ~/.ssh
+brew install mkcert # replace with another package manager for linux distro
+brew install nss # need to install certutil before running `mkcert -install` so the CA can be automatically installed in Firefox
+
+# at this point, open any https website in Firefox before running the below commands
+
+mkcert -install
+mkcert -key-file localhost_key.pem -cert-file localhost_cert.pem localhost 127.0.0.1
+cat localhost_cert.pem > localhost_fullchain.pem
+cat "$(mkcert -CAROOT)/rootCA.pem" >> localhost_fullchain.pem
+```
+
+Now, navigate to your project directory, wherever the repo was cloned to, for example cd `~/Sites/work/website` and copy the `.pem` files into the repo root. These keys are .gitignored by default.
+
+Or run the below command to copy the files to your currently `cd`’d dir automatically
+
+```bash
+cp -v ~/.ssh/localhost_cert.pem ~/.ssh/localhost_key.pem .
+```
+
+### Environment variables

+```ini

+SERVER_ENV=development
