Continued incremental improvements to the initial code base. Additional activity shown below. The primary method of discussion has been moved to Discord.
Additional work:

Current Plans
Next steps include:

- Allow the use of SqlMerkleState with-in existing transactions
- Re-evaluate threading model for batch scheduling and execution
- Setup a documentation site to help explain/advocate the project

| > Setup a documentation site to help explain/advocate the project I can highly recommend ReadTheDocs and it's GitHub integrations. We use it on Cactus and I've seen it used by many other HL projects as well. I don't know if you already picked something for this or not, but just in case you are still looking, here it is.

| The answers to the diversity questions don't really provide the info that is sought for. Following the statement that the maintainers haven't changed, it would be better to list them along with their affiliations than have the reader dig this information out. And the same for the contributors. Thanks.

| Peter, glad to hear ReadTheDocs has been a good experience. We have a jekyll template that Grid and Sawtooth are using and that's similarly been a good experience. Posted by amundson at May 25, 2022 14:55 |
| Arnaud, thanks for the feedback. We can link the the project's maintainers file in the future so its easier to find; I see some projects are doing that in the maintainers section and it makes sense. Posted by amundson at May 25, 2022 15:00 |
