All modules share some common options, like `enable` and `disable`.
When `enable` is `true` this will enable the module for all supported languages,
if you want to disable the module for some languages you can pass a list to the `disable` option.
For more fine-grained control, `condition` takes a function and whenever it returns
`false` the module is disabled for that buffer.
The `condition` function is called once when a module starts in a buffer and
received the language and the buffer number as arguments.

Options that define or accept a keymap use the same format you use to define
keymaps in Neovim, so you can write keymaps as `gd`, `<space>a`, `<leader>a`
`<C-a>` (control + a), `<A-n>` (alt + n), `<CR>` (enter), etc.
