-Why this is useful? Go has rules on how it can automatically select value and method receivers, which is complex and can lead to bugs.
+Go has rules on how it can automatically select value and method receivers, which is complex and can lead to bugs.
 It is also common style recommendation [Go wiki](https://github.com/golang/go/wiki/CodeReviewComments#receiver-type) and [Google Go style guide](https://google.github.io/styleguide/go/decisions#receiver-type):
 
 > Don't mix receiver types. Choose either pointers or struct types for all available methods.
 
-## Requirements
-
-```bash
-go install github.com/nikolaydubina/smrcptr@latest
-```
-
-## Features
-
-### Skipping methods from standard packages
-
-Very common methods that has to have method receivers are skipped with `-skip-std=true` by default.

-### Return Status Code
-
-When issue is detected, related info is printed and status code is non-zero.
-This is similar as other `go vet` and linters.
-This allows convenient use in CI.
-
-### Constructor
-
-It is also useful to detect if "construtor" functions that commonly start with `New...` returns value that matches used in receivers.

-$ smrcptr --constructor=true ./internal/...
