     93 ## Project Structure
     94 
     95 Inside your Fes project, you'll see the following directories and files:
     96 
     97 $$$$$$
     98 .
     99 ├── Fes.toml
    100 ├── README.md
    101 └── www
    102     └── index.lua
    103 $$$$$$
    104 
    105 Fes looks for $$.lua$$ files in the $$www/$$ directory. Each file is exposed as a route based on its file name.
    106 
    107 ## Commands
    108 
    109 All commands are run from the root of the project, from a terminal:
    110 
    111 | Command                   | Action                                           |
    112 | :------------------------ | :----------------------------------------------- |
    113 | $$fes run .$$               | Runs the project at $$.$$                          |
