+# Acai Modular System
+
+## Modules
+
+Modules are the visual building blocks of Acai websites. Each module lives in `template/estandar/modulos/<module-id>/`.
+
+### File structure
+
+```
+<module-id>/
+├── index-base.tpl    # Source Twig template (EDIT THIS)
+├── index.tpl         # Compiled output (auto-generated, do NOT edit)
+├── style.css         # Module-scoped styles
+└── script.js         # Module JavaScript
+```
+
+### Twig Templates
+
+<!-- TODO: Document Twig syntax, variable access, builder vars -->
+
+### Custom Twig Filters
+
+<!-- TODO: Document custom filters available in Acai (e.g., |translate, |slugify, etc.) -->
+
+### Builder Variables
+
+<!-- TODO: Document how builder vars work, how to access them in templates -->
+
+### Calling Modules from Other Modules
+
+<!-- TODO: Document how to include/call modules from other modules or general sections -->
+
+
+## General Sections
+
+General sections are reusable layout blocks (headers, footers, sidebars) shared across pages.
+
+<!-- TODO: Document how general sections differ from modules, where they live, how to create/edit them -->
+
+
+## CSS & JavaScript
+
+### Module Styles (`style.css`)

+<!-- TODO: Document scoping rules, CSS conventions -->
+
+### Module Scripts (`script.js`)
