 # Open Software Summer School
 
-**The NIU Open Software Summer School brings together researchers, developers, and users of open-source neuroscience software for some hands-on training, community-building and hacking.**
 
-The [the 2025 event](2025/index) (known as Open Software Week) brought together 44 attendees from 12 countries to learn about open source approaches for handling large images, processing microscopy data and analysing video behavioural data. 
-The event will return, **bigger and better**, in summer 2026 at the [Sainsbury Wellcome Centre](https://maps.app.goo.gl/CzWFFjXJZwX87aMj6) 
-in London, U.K. Details are being finalised, but take a look at the details of [the 2025 event](2025/index) for an idea of what you can expect.
+We are excited to announce the second **NIU Open Software Summer School**, taking
+place in **August 2026** at the [Sainsbury Wellcome Centre](https://maps.app.goo.gl/CzWFFjXJZwX87aMj6) 
+in **London, UK**. This event will bring together researchers, developers, and users of open-source software for some hands-on training, community-building and hacking.

-Dates of the 2026 event are TBC, but we expect applications to open in early 2026.
+[The 2025 event](2025/index) (known as Open Software Week) brought together 44 attendees from 12 countries to learn 
+about open-source approaches for handling large images, processing microscopy data and analysing video behavioural data. 
+In 2026, we will return, with an expanded two-week program adding a new *Extracellular Electrophysiology* track, 
+additional satellite events, guest lectures and opportunities for researchers to present their own work. 
+
+## Schedule
+![](/_static/osw_images/OSSS_2026_schedule.png)
+
+
+There are four tracks targeted to different audiences.
+We encourage you to read each track's description and choose the one(s) that best fits your interests. More details 
+be added before registration opens.

+:::{admonition} Registration
+:class: info
+You may register for week 1, week 2 or both. However, you can only register for one track per week, i.e:
+
+- **Week 1**: either *Animals in Motion* or *Large Array Data*.
+- **Week 2**: either *BrainGlobe* or *Extracellular Electrophysiology*.
 :::
 
+## Key Dates
+
+| Date | Event |
+| --- | --- |
+| December 1st 2025 | Applications open |
+| January 31st 2026 | Applications close |
+| March 2026 | Applicants are notified of acceptance |
+| July 2026 | Optional preparatory month begins |
+| August 17-21 2026 | Week 1: *Animals in Motion* & *Large Array Data* |
+| August 24-28 2026 | Week 2: *BrainGlobe* & *Extracellular Electrophysiology* 
+
+## Preparatory month
+All four tracks require a basic knowledge of scientific Python programming. If you don't have this background, that's 
+totally fine, we will be running an asynchronous preparatory course in the month before the summer school. Training 
+materials and exercises will be shared with participants, and OSSS instructors will be available to answer any questions.
+
+**This preparatory course is mandatory for those without Python experience, and requires a minimum of four hours per week 
+commitment for four weeks prior to the summer school**
+
+
+
+## Fees
+- **Academic**: £300 per week
+- **Industry**: £600 per week
+
+### Financial Assistance
+A number of fee waivers will be available to applicants who would not otherwise be able to attend the summer school. 
+A limited number of travel stipends will also be available, but we encourage applicants to apply for 
+[independent travel funding](funding).
