# Welcome to the 39. Chaos Communication Congress Public Wiki
**The wiki is as always work in progress – come back later to find even more content.**
You are on the splash page. From here you can navigate to various topics. There will be wiki content not linked to the slash page – you can find them by [browsing the latest wiki changes](https://events.ccc.de/congress/2025/hub/de/wiki_history).
#### TICKET EXCHANGE
This year we have created a safe way to resell your ticket. At the [**Second Hand Ticket Exchange**](https://tickets.events.ccc.de/39c3/secondhand/) you can sell your spare ticket within the last minute. For the ticket exchange we only accept credit cards.
#### GETTING TO 39C3
We collected some basic information on how to get to 39C3 on [this page](https://events.ccc.de/congress/2025/infos/travel.html). If you offer or seek a ride you can use the [[ridesharing|**Ride Sharing**]] page to find a offer a ride. Safe the environment, travel together and get to know a hcker you did not know before!
#### ACCCOMODATION
Now you got your ticket, you packed your bags and got a ride you need a place to stay. As a very basic accomodation we offer a place to sleep in a school gym. Find all information about it on [**this dedicated gym page**](https://events.ccc.de/congress/2025/infos/facilities.html#gyms). If you live in Hamburg and want to host a fellow hacker you can announce so by entering dome information on the
[[schlafplatz|**couch/sleeping place Sharing**]] page. This is another great way to get to know a hacker you have not known until now.
#### FAHRPLAN ON YOU MOBILE DEVICE
For four days 39C3 has to offer hundreds of single events. Brwosing the [Fahrplan](https://events.ccc.de/congress/2025/hub/de/schedule) on your phone can be difficult. There are some [[apps|**Fahrplan Apps**]]. Pleas ehelp fellow nerds by completing the page with information about apps you can not find on the page at the moment.
