@mnencia thanks for your contribution!

Codes looks good overall, could you help update README(sections, help command and so on)?

[mnencia]

@daixiang0, thanks for the review. I've added the documentation.

hi @mnencia / @daixiang0 , I am getting this error when running via golangci-lint

• can't run linter goanalysis_metalinter: gci: failed to parse section "Blank": section alias "Blank" not registered with parser

may I ask what am I missing?

I have the following config:

linters-settings:
  gci:
    sections:
      - Blank
    custom-order: true

You can download binary directly to try the latest version which includes this feature.
