The following changes have been added to this PR:
•	Fix minor grammatical errors.
•	Capitalize terms such as Commands, Modules and such, as the context is specific to the lib.
•	Wrap methods and properties in code blocks.

The docs page currently has several issues that remains to be fixed.

1. 
```md
>[!WARNING]
>This article is out of date and has not been rewritten yet.
Information is not guaranteed to be accurate.
```

The docs doesn't necessarily seem "out of date" as the warning claims. The basics seem pretty relevant to the latest version of the lib.

2.
>“To manually load a module, invoke [CommandService.AddModuleAsync], by passing in the generic type of your module and optionally, a dependency map.”

The latter part of the sentence seems off. Where should the user pass the dependency map to? It seems to suggest that `AddModuleAsync` has an argument to pass the dependency to. If it is referring to `AddModuleAsync(Type type)`, then I feel like it should be clarified here - or perhaps change the wording of the sentence.

3.
>“First, you need to create an @System.IServiceProvider You may create your own IServiceProvider if you wish.” 

Any mention of @System.IServiceProvider is currently broken on the docs.

4.
>“Submodules are Modules that reside within another one. Typically, submodules are used to create nested groups (although not required to create nested groups).”

Clarification on the part after "although?"

5.
>“Finally, pass the map into the LoadAssembly method. Your modules will automatically be loaded with this dependency map.”

Where is this `LoadAssembly` method?

6.
```md
>[!NOTE]
>Preconditions can be applied to Modules, Groups, or Commands.
```

The docs should mention `ParameterPreconditionAttribute`'s existence.
