## Project Structure

Inside your Fes project, you'll see the following directories and files:

$$$$$$
.
├── Fes.toml
├── README.md
└── www
    └── index.lua
$$$$$$

Fes looks for $$.lua$$ files in the $$www/$$ directory. Each file is exposed as a route based on its file name.

## Commands

All commands are run from the root of the project, from a terminal:

| Command                   | Action                                           |
| :------------------------ | :----------------------------------------------- |
| $$fes run .$$             | Runs the project at $$.$$                        |

## Gemini

Fes supports many different protocols. One of which is the Gemini protocol; this
protocol has specific encryption standards which makes the providing $$key.pem$$
and a $$cert.pem$$ files. *Please* regenerate these files by running this command.
$$$$$$
openssl req -x509 -nodes -days 365 \
  -newkey rsa:2048 \
  -keyout key.pem \
  -out cert.pem \
  -subj "/C=US/ST=State/L=City/O=Local Development/OU=Localhost/CN=localhost" \
  -addext "subjectAltName=DNS:localhost,IP:127.0.0.1,IP:::1" \
  -addext "basicConstraints=CA:FALSE" \
  -addext "keyUsage=digitalSignature,keyEncipherment" \
  -addext "extendedKeyUsage=serverAuth"
