-  - go get github.com/willf/bitset
-  - go get github.com/mschoch/smat
+Dependencies are fetched automatically by giving the `-t` flag to `go get`.

 Note that the smat library requires Go 1.6 or better.

+In general, it should not generally be considered safe to access

+provide synchronization. Typically this is done by using channels to pass

 ### Compatibility with Java RoaringBitmap library
 
-You can read bitmaps in Go (resp. Java) that have been serialized in Java (resp. Go)
-with the caveat that the Go library does not yet support run containers. So if you plan
-to read bitmaps serialized from Java in Go, you might want to call ``removeRunCompression``
-prior to serializing your Java instances. This is a temporary limitation: we plan to
-add support for run containers to the Go library.
