+Usage
+---------
+The discogs package provides a client for accessing the Discogs API. 
+First of all import library and init client variable. According to discogs api documentation you [must provide your user-agent](https://www.discogs.com/developers/#page:home,header:home-general-information). 
+```go
+  package main
+    
+  import (
+    "github.com/irlndts/go-discogs"
+  )
+ ```
+ ```go
+ client := discogs.NewClient().UserAgent("TestDiscogsClient/0.0.1 +example.com")
+``` 
+
+#### Releases
+```go
+  params := &discogs.ReleaseParams{Release_id: "8138518"}
+  release, _, err := d.Release.Release(params)
+  
+  fmt.Println(fmt.Println(release.Artists[0].Name, " - ", release.Title)) // St. Petersburg Ska-Jazz Review  -  Elephant Riddim
+```
+
+#### Artists
+```go
+  params := &discogs.LabelParams{Label_id: "890477", Page: 2, Per_page: 3}
+  label, _, err := d.Label.Releases(params)
+
+  for _, release := range label.Releases {
+    fmt.Println(release.Title)
+  }
+
+  /*
+    Someday / I Hate Everything About You
+    Spy Potion
+    Surf Attack From Russia
+  */
+```
+
+etc. 
+More examples - soon
