-## Related packages
+## Development

-These repos are independent and reusable modules, but are tightly integrated into Lotus to make up a fully featured Filecoin implementation:
+The main branches under development at the moment are:
+* [`master`](https://github.com/filecoin-project/lotus): current testnet.
+* [`next`](https://github.com/filecoin-project/lotus/tree/next): working branch with chain-breaking changes.
+* [`ntwk-calibration`](https://github.com/filecoin-project/lotus/tree/ntwk-calibration): devnet running one of `next` commits.

+### Tracker
+
+All work is tracked via issues. An attempt at keeping an up-to-date view on remaining work towards Mainnet launch can be seen at the [lotus github project board](https://github.com/orgs/filecoin-project/projects/8). The issues labeled with `incentives` are there to identify the issues needed for Space Race launch.
+
+### Packages
+
+The lotus Filecoin implementation unfolds into the following packages:
+
+- [This repo](https://github.com/filecoin-project/lotus)
 - [go-fil-markets](https://github.com/filecoin-project/go-fil-markets) which has its own [kanban work tracker available here](https://app.zenhub.com/workspaces/markets-shared-components-5daa144a7046a60001c6e253/board)

-## Contribute
-
-Lotus is a universally open project and welcomes contributions of all kinds: code, docs, and more. However, before making a contribution, we ask you to heed these recommendations:
-
-1. If the proposal entails a protocol change, please first submit a [Filecoin Improvement Proposal](https://github.com/filecoin-project/FIPs).
-2. If the change is complex and requires prior discussion, [open an issue](github.com/filecoin-project/lotus/issues) or a [discussion](https://github.com/filecoin-project/lotus/discussions) to request feedback before you start working on a pull request. This is to avoid disappointment and sunk costs, in case the change is not actually needed or accepted.
-3. Please refrain from submitting PRs to adapt existing code to subjective preferences. The changeset should contain functional or technical improvements/enhancements, bug fixes, new features, or some other clear material contribution. Simple stylistic changes are likely to be rejected in order to reduce code churn.
-
-When implementing a change:
-
-1. Adhere to the standard Go formatting guidelines, e.g. [Effective Go](https://golang.org/doc/effective_go.html). Run `go fmt`.
-2. Stick to the idioms and patterns used in the codebase. Familiar-looking code has a higher chance of being accepted than eerie code. Pay attention to commonly used variable and parameter names, avoidance of naked returns, error handling patterns, etc.
-3. Comments: follow the advice on the [Commentary](https://golang.org/doc/effective_go.html#commentary) section of Effective Go.
-4. Minimize code churn. Modify only what is strictly necessary. Well-encapsulated changesets will get a quicker response from maintainers.
-5. Lint your code with [`golangci-lint`](https://golangci-lint.run) (CI will reject your PR if unlinted).
-6. Add tests.
-7. Title the PR in a meaningful way and describe the rationale and the thought process in the PR description.
-8. Write clean, thoughtful, and detailed [commit messages](https://chris.beams.io/posts/git-commit/). This is even more important than the PR description, because commit messages are stored _inside_ the Git history. One good rule is: if you are happy posting the commit message as the PR description, then it's a good commit message.
