 Gota: DataFrames, Series and Data Wrangling for Go
 ==================================================
 
+Meet us on Slack: Slack: [gophers.slack.com](https://gophers.slack.com) #go-gota ([invite](https://gophersinvite.herokuapp.com/))
+
 This is an implementation of DataFrames, Series and data wrangling
 methods for the Go programming language. The API is still in flux so

+# ROADMAP
+
+## [0.12.0]
+
+- more functionality of [Pandas](https://pandas.pydata.org/pandas-docs/stable/reference/index.html) (without copying the API)
+- more functional style of the API ([like Scala has](https://www.scala-lang.org/api/current/scala/collection/immutable/List.html))
+- deprecate API parts not fitting the functional style
+
+## [0.13.0]
+
+- maybe Go Generics are in place
+- see, how we can shift towards more typesavety (using interface{} everywhere is ugly)
