+### TBD source directory refactoring. Should we look to put .pas and possibly other files in a src subdirectory?
+
+1 - How to write and contribute unit tests
+There aren't any unit tests. This may be added to the roadmap. Code refactoring will be needed to be able to support unit testing.
+### TBD add unit testing framework and refactor to support it to the long term roadmap
+
+1 - How to build, run, test the source code
+
+1 - How to build an executable
+
+1 - Production builds are currently created for each release by W7SST
+### TBD add automated nightly test builds and versioned release builds to the long term roadmap
+### TBD perform builds via github actions? if not then maybe GitLab, Travis or Jenkins?
