 # maps
 
-golang maps
+###maps
-可对map根据key进行排序
+可根据map的key按照有序排序的map包
+
+###使用:
+- go get -u github.com/cowardmrx/maps
+```go
+// Set
+maps := NewMaps()
+maps.Set("key1", "123123")
+
+// Exist
+maps.Exist("key1")
+
+// Get
+maps.Get("key")
+
+// Delete
+maps.Delete("key1","key2")
+
+// GetMapsKeys return a []string
+maps.Keys() 
+
+// GetMapsValues return a []interface
+maps.Values()
+
+// GetMapsOriginMap get this maps origin data return a map[string]interface
+maps.OriginMap()
+
+// SortKey sort this maps by keys
+maps.SortKey()
+
+// other example ./maps_test.go
