Hi everybody! I have started writing custom Detekt rules, but I’ve run into some difficulties. Could you please tell me where I can find the documentation for PSI? I need to understand what kind of nodes are visited in the visitXXX functions and how to correctly write some rules for them.

The easiest way is to check <https://github.com/JetBrains/kotlin/blob/35d2be25b2e938ace84299948fa5d78b5b120543/compiler/psi/src/org/jetbrains/kotlin/psi/KtVisitor.java#L22|sources> of `KtVisitor`

To be more specific about my problem, I tried to find occurrences of the `SomeEnum.name` property using `visitDotQualifiedExpression`. I found them, but I need to ensure that the .name expression belongs only to an `Еnum`. I then tried to verify this using:

```val receiverKotlinTypeInfo: KotlinTypeInfo? =
  bindingContext[BindingContext.EXPRESSION_TYPE_INFO, receiverExpression]```
However, it returns null. I suppose I am doing something wrong at this stage. This is why I need more information about `BindingContext` or other related concepts.

I don't know how detect works under the hood, so I can't help here
