¶ OpenWrt project infrastructure
The OpenWrt project relies on the considerable efforts of its volunteer developers, the core documentation team, the forum moderators, and the host of people who're actively using and testing the products. The OpenWrt team has also provisioned many physical and virtual servers that "make the OpenWrt project go".

¶ Worker hardware requirements
- CPU: a good worker needs 4-8 CPU cores for phase1/images, and 8-16 CPU cores for phase2/packages. Larger machines are split into several workers using Docker.
- Memory: each worker needs a minimum of 1 GB of RAM for each CPU hardware thread, 2 GB / thread is preferred. For example, a 16 cores / 32 threads machine needs between 32 GB and 64 GB of RAM in total.
- Disk: each worker needs either 50 GB of disk space (for phase1/images) or 150 GB of disk space (for phase2/packages).

¶ Finances
- Each of the Hetzner servers costs about 50 Euros per month, for a total of 150 Euros/month.
- There is a small annual charge (20-40 Euros) for registering the domain names, etc.
- As of late 2016, two core team members are personally covering the costs of the Hetzner servers while another core team member picks up the other fees. So far, no one has stepped up to fund the new servers that will be required in the coming months.
- Other private parties generously donate their time & compute cycles, you know who you are and we thank you.
