# Transitioning from our previous GitHub Site.

After 8 years of development and 5 years in Open Source, we began in May, 2019 the important migration from a stand-alone GitHub site to being a member of the [Apache Software Foundation](https://apache.org) community.

While we undergo this migration, we beg your patience. 

As the repositories under GitHub.io/DataSketches migrate they will disapear from the the GitHub.com/DataSketches organization page. Please refer to this list be directed to the new locations. 

View all of our Apache DataSketches repository components as a [list](https://github.com/apache?utf8=%E2%9C%93&q=datasketches)

**Note** The following names in **BOLD** are of the old github.com/datasketches/ organization repositories.
