+## Community
+
+### How is OSO supported?
+
+Open Source Observer is a public good.
+All of our code is [open source](https://github.com/opensource-observer/oso/)
+All of our data sets and models are [open data](../integrate/overview/index.mdx).
+All of our infrastructure is [open](https://dagster.opensource.observer/locations) too.
+If we are going to transform funding for public goods,
+we need to live by an open source ethos.
+We are supported by grants from our generous partners, which pay for
+the platform development, running the data pipeline regularly,
+and community incentives for data and insights.
+If you want to support us, please reach out at
+[[email protected]](mailto:[email protected]).
+
+### I'm brand new. How do I get started?
+
+Join our [Discord](https://www.opensource.observer/discord).
+This is where we hang out most of the time and usually the best place
+to introduce yourself and ask questions.
+If you know what you're looking for, our docs are the best place
+to search for the answer.
+We do also occasionally host public
+[data challenges](../contribute/challenges/index.md)
+if you're looking for more structure.

+
+## Data
+
+### How can we analyze different open source ecosystems?
+
+Our ambition with OSO is to transform how we measure impact
+across _any_ open source ecosystem.
+However, you'll notice that most of our existing data
+is skewed towards certain ecosystems that we work with closely.
+In order to instruct the indexer to also analyze your project,
+you must add your project to
+[oss-directory](https://github.com/opensource-observer/oss-directory/).
+We have detailed instructions on how to do that
+[here](../contribute/project-data.md).
+
+### How often do you index / refresh your data?
+
+Our data pipeline currently is set to run weekly (on Sundays).
+Our existing setup involves large jobs that take days to complete.
+We are working on optimizing our performance and cost structure
+so that we can run this more frequently.
+
+---
+
+## Product
+
+### How can I request a new feature?
+
+We live and breathe in our
+[GitHub issues](https://github.com/opensource-observer/oso/issues/).
+In order to help us triage, please search to see if an existing issue
+already exists for your request before filing a new issue.
+You can monitor our progress on our
+[project board](https://github.com/orgs/opensource-observer/projects/3/views/10).
+
+### How is OSO different from XYZ tool?
+
+What distinguishes OSO is the power of our community,
+where every part of our stack is supported by a diverse network of contributors, including:
+
+- data indexers who provide various raw data sources
+- data modelers who help us refine our metrics and data models
+- data engineers who keep the pipeline running smoothly
+- data integrations that share OSO metrics and insights across various applications
+
+Together, we are building a rich dependency tree of open data sets,
+which you can see on our
+[Dagster dashboard](https://dagster.opensource.observer/assets).
+Every data asset is maintained by a dedicated contributor and refreshed regularly.
+Each contributor has their own upstream dependencies and downstream dependents.
+New contributors can build on any existing data asset, including hundreds
+of incredible intermediate models, from user reputation models to retention/churn models.
+We are building the biggest data network with the best open source community.
