[Feature] Better docs

[NothingEverHappens]

While this library looks really cool, it's really hard to understand how to use it.

there are only 8 usages of this lib on github (half of them - this repo):
https://github.com/search?l=TypeScript&q=creator+ts-creator&type=Code

import creator from 'ts-creator'

const generatedFactoryCode = creator(`const foo = "your code here"`)

This generates a string?
I was hoping the result to be a list of ts.Statement, and I'm not sure how to convert those? Eval?

import { transformSourceFile } from 'ts-creator'

declare const file: ts.SourceFile
const factoryFile = transformSourceFile(file)

It's not clear what this does, what's factoryFile, and why does it need to take a source file?

import { transformNode } from 'ts-creator'

declare const node: ts.Expression
const factoryNode = transformNode(node)

Same as above. It promises some kind of transformation, but it's not clear how to use it.

https://ts-creator.js.org/ - The playground it cool, but it comes empty, and there are no samples.
If you look at the typescript playground it comes pre-populated with code, and has lots of samples that people can play with to better understand how things work.

I'd be happy to send a PR for some of those things, but may need some clarification first.

in fact, I have such confusion about what could I do to use this package, what the purpose of it? it seems interesting, but I don't get the point.
