-
-Package ini provides INI file read and write functionality in Go.
-
-## Features
-
-- Load from multiple data sources(`[]byte`, file and `io.ReadCloser`) with overwrites.
-- Read with recursion values.
-- Read with parent-child sections.
-- Read with auto-increment key names.
-- Read with multiple-line values.
-- Read with tons of helper methods.
-- Read and convert values to Go types.
-- Read and **WRITE** comments of sections and keys.
-- Manipulate sections, keys and comments with ease.
-- Keep sections and keys in order as you parse and save.
-
-## Installation
-
-The minimum requirement of Go is **1.6**.
-
-```sh
-$ go get gopkg.in/ini.v1
-```
-
-Please add `-u` flag to update in the future.
