+## Scala open source
+
+Want to start making open-source contributions to projects in the
+Scala ecosystem?
+
+Scaladex lists [projects welcoming contributions](https://index.scala-lang.org/search?q=&contributingSearch=true).
+
+Also, on GitHub, a common convention is to use the label "good first issue"
+on issues that are especially easy on-ramps to getting started in
+a particular repo:
+
+* "good first issue" tickets: https://github.com/search?q=type%3Aissue+label%3A%22good+first+issue%22+language%3AScala+state%3Aopen&type=Issues
+
+And, some repos also use a "help wanted" label if the maintainers
+especially desire contributor attention:
+
+* "help wanted" tickets: https://github.com/search?q=type%3Aissue+label%3A%22help+wanted%22+language%3AScala+state%3Aopen&type=Issues
