These are the core modules of this desktop.
There are currently the following modules, in the order of loading:
1) error.lua    - Error handling 
2) vars.lua     - Variable definitions
3) style.lua    - ``beautiful`` theme and style definitions
4) binds.lua    - Binds
5) layout.lua   - Wibar layout
6) rules.lua    - Rules
7) signals.lua  - Signals

Some of the modules were further split into distinct components:
1) client.lua   - Additional client hook to be run when a client is created.
2) titlebar.lua - Titlebar configuration, also run when a client is created.
3) widgets/*    - Default widgets and their parameters.

Notice that Error handling and Variable definitions come before beautiful
initialization. That is normal. Those modules don't depend on any of the
above, therefore they are loaded before anything else.

Additionally, notice that Binds come before layout. That is not exactly how it
was in the default rc.lua, but it is important to load them in exactly that
order. Widgets, which are called from layout.lua, override the global bindings
table. If you load binds after the layout is loaded, the bindings are reset to
defaults.

Everything else is kept in exactly the same order as it was in the default
rc.lua

Additionally, it should be noted that all widgets in this config are entirely
independent. Simply not loading them will not load any keybindings or break
the config. Therefore, if you want to change any keybindings for the widgets,
you would want to search for them in their respective modules.
