-The `--offline` flag tells the CLI to use the templates, commands, and scripts bundled inside the wheel instead of downloading from GitHub.

-> **Deprecation notice:** Starting with v0.6.0, `specify init` will use bundled assets by default and the `--offline` flag will be removed. The GitHub download path will be retired because bundled assets eliminate the need for network access, avoid proxy/firewall issues, and guarantee that templates always match the installed CLI version. No action will be needed — `specify init` will simply work without network access out of the box.

+
+#### Example: Using a private GitHub-hosted catalog
+
+```bash
+# Authenticate with a token (gh CLI, PAT, or GITHUB_TOKEN in CI)
+export GITHUB_TOKEN=$(gh auth token)
+
+# Search a private catalog added via `specify preset catalog add`
+specify preset search my-template
+
+# Install from a private catalog
+specify preset add my-template
+```
+
+The token is attached automatically to requests targeting GitHub domains. Non-GitHub catalog URLs are always fetched without credentials.
