+## `texforge init`

+Interactive wizard. Auto-detects the context:
+
+- If a `.tex` file with `\documentclass` is found in the current directory — migrates the existing project (asks for title and author, generates `project.toml`)
+- Otherwise — guides creation of a new project (asks for name and template)
+
+```bash
+# Existing LaTeX project
+cd mi-tesis-existente/
+texforge init
+
+# Empty directory
+mkdir mi-nuevo-doc && cd mi-nuevo-doc
+texforge init
