 - `startup/servers.lua` creates the boot eventloop, runs autostart server files (which register handlers and return), then runs the shell and the eventloop in parallel via `parallel.waitForAny`.
 - Preserve `periphemu` guards used for CraftOS-PC emulation; see [`docs/craftos_pc_glossary.md`](docs/craftos_pc_glossary.md) for upstream emulator references.
 - TrapOS ships as packages, each described by `packages/<name>/ccpm.json` (`name`, `version`, `dependencies`, `files`, `autostart`); `packages/index.json` lists them. Source files stay in place — descriptors only reference them. To ship a new file, add it to the right package's `files` (and `autostart` if it is a server). `packages/trapos/ccpm.json` is the full OS meta-package. See [ADR-0010](docs/adrs/adr-0010-ccpm-package-manager.md).
-- `install-ccpm.lua` is the one-time wget bootstrap. It installs only `trapos-core`/`ccpm`, seeds the default `guillaumearm/cc-libs` registry on `master` (or `next` with `--beta`), and tells users to run `ccpm update` then `ccpm install trapos`.
+- `install-ccpm.lua` is the one-time wget bootstrap. It installs only `trapos-core`/`ccpm`, seeds the default `guillaumearm/cc-libs` registry as a `gitea` registry on `git.trapcloud.fr` tracking `master` (or `next` with `--beta`), and tells users to run `ccpm update` then `ccpm install trapos`. The legacy `github` registry type still resolves but is deprecated.
 - `ccpm` (in `trapos-core`) is the package manager: `apis/libccpm.lua` is the testable core (factory with injectable `http`/`stateDir`/`installRoot`), `programs/ccpm.lua` the CLI. State: `/trapos/ccpm.json` (registries), `/trapos/ccpm.lock.json` (installed packages), and `/trapos/ccpm.cache.json` (available packages from `ccpm update`). Never use the word "manifest" in ccpm — it is reserved for the OS manifest.
 - Add new servers to `startup/servers.lua` as needed.
