 ### Testing Architecture
@@ -223,6 +223,16 @@ Two logging modes:
 ### Running Plain2Code from Another Directory
 The tool can be run from any directory by providing an absolute or relative path to the `.plain` file. All paths (build folder, log file, templates) are resolved relative to the `.plain` file's directory, not the current working directory, unless explicitly overridden via CLI arguments.
 
+### Standard Template Library
+
+`standard_template_library/` is a git subtree sourced from the `plainlang-examples` repository. It is **not** updated automatically — you must pull changes manually when the templates change upstream:
+
+```bash
+git subtree pull --prefix=standard_template_library git@github.com:Codeplain-ai/plainlang-examples.git main --squash
+```
+
+The subtree does not track a branch pointer. The branch (`main` above) is just an argument passed at pull time — git uses the `git-subtree-split` hash embedded in the commit history to determine what's new since the last sync.
+
 ### Windows Support
 Windows users must use WSL (Windows Subsystem for Linux). The codebase has some platform-specific script handling (`.ps1` for Windows, `.sh` for Unix).
