+
+## Funding
+
+Unlike previous years, participation costs for this year's summit are covered
+only for those invited as part of the special track on statistics (for that, we have targeted grant funding).
+
+Project maintainers, please reach out to your individual projects to determine
+whether they have funds to sponsor your attendance.
+
+## Logistics
+
+We have space for 40 participants for three days and four nights.
+This will be an invite-only event that requires upfront agreement to:
+(a) take part in one or more pre-summit planning meetings,
+(b) collaborate with fellow participants on a work plan,
+(c) attend the summit in-person, and
+(d) participate, to whatever degree possible, in several months of post-summit implementation.
+
+### Airport to hotel
+
+There is no need to get a rental car or taxi/ride-share, as the airport and the UW campus area is well-served by bus and rail.
+We recommend using Link Light Rail to get from the airport to the hotel. It takes approximately an hour and costs $3.25.
+The closest station to the hotel is "U-District" (0.3mi away), which is a new station opened in 2021 and is not to be confused with the station in Downtown called, "University St", neither with "University of Washington".
+
+### Food
+
+Coming soon
+
+### Participants
+
+Participants are recruited from the community of developers of packages
+such as NumPy, SciPy, matplotlib, xarray, pandas, scikit-image, scikit-learn,
+NetworkX, and IPython, as well as domain stacks including Astropy, Pangeo, and
+scikit-HEP.

+## About
+
+### Goals
+
+The 2025 Scientific Python Developer Summit will focus on statistics, optimization, sparse data, plotting, and dataframes.
+
+The Developer Summit provides an opportunity for core developers
+from the scientific Python ecosystem to come together to:
+
+#### 1. Improve joint infrastructure
+
+Collaborate to adopt and improve infrastructure, tools, and processes
+used across projects. This includes infrastructure already described
+in Scientific Python Ecosystem Coordination documents (SPECs), as well
+as, but not limited to, tools for documentation, testing, benchmarking,
+packaging, and Continuous Integration (CI).
+
+#### 2. Better coordination of the ecosystem
+
+A central goal of the Scientific Python project and, by implication, the summit, is to better coordinate maintenance of the different projects.
+
+#### 3. Work on shared strategic goals
+
+A strategic plan would identify core needs and future challenges of the scientific Python community.
+Rather than focusing on the technical details of one particular project or domain area, the strategic plan would discuss the challenges shared across projects and domains.
+The plan can be used by the community as supporting evidence when applying for grants.
+
+### Dates
+
+The summit is held May 11-15, 2025 in Seattle, WA.
+
+Attendees should preferably arrive the day before the summit starts, and stay for the entire duration of the summit.
+
+### Pre-Summit Planning
+
+See [planning issues](https://github.com/scientific-python/summit-2025/issues).
+
+Participants will be responsible for attending two or more one-hour video meetings (the planning meetings mentioned above) and for
+participating in a planning repository via PRs, issues—as both contributors and reviewers.
+There is no heavy top-down structure: participants themselves will organize the work that needs to be done ahead of time.
+They will decide on topics, divide the work, and schedule the meeting.
+
+### Summit Execution
+
+The goal of the summit is to be a hands-on work meeting.
+That said, there will be some free time scheduled to brainstorm new ideas, and to discuss current community projects and activities.
+
+### Post-Summit Implementation
+
+After the meeting, attendees will collaborate on their assigned tasks until completion.
+
+## Meeting notes
+
+To be posted.
