 The installer writes `ti` and `ti-drive9` to `~/.ti/bin` without sudo. Add the `export PATH=...` line to your shell profile to make it persistent.
 
-The macOS/Linux installer downloads both binaries and their checksum files from CDN-fronted sources and verifies the checksums before installation.
+The shell and PowerShell installers download `ti` from GitHub Releases and `ti-drive9` from the [`drive9-fe` GitHub repository](https://github.com/mem9-ai/drive9-fe/tree/main/site/releases). Both installers and `ti update` verify the companion against `checksums.txt` from the same GitHub directory before installation.

 - Installation and update do not require sudo.
 - Installers do not edit shell profiles automatically; they print the command that prepends `~/.ti/bin` to `PATH`.
-- Installers support ti release version pinning and checksum verification. The shell installer downloads the companion and its checksums from Drive9's CloudFront-fronted release endpoint (`releases.drive9.ai/latest`); the PowerShell installer and updater use Drive9's origin release endpoint. These companion sources are unversioned; ti does not yet negotiate a companion version range.
+- Installers support ti release version pinning and checksum verification. The shell installer, PowerShell installer, and updater download the companion and `checksums.txt` from `mem9-ai/drive9-fe` on GitHub (`main/site/releases`, served by `raw.githubusercontent.com`). This companion source is unversioned; ti does not yet negotiate a companion version range.
 - `ti update --check` checks explicitly; there is no background update.
 - `ti update` is itself explicit consent and does not require `--yes`.
 - The updater stages and verifies ti and its companion before replacement.
