+
+- `--target`: rama principal sobre la que se taggea. Por defecto, la rama actual. Debe ser una de las
+  ramas principales configuradas.
+- `--token`: Access Token del remoto. Si se pasa, se asume que corre en un pipeline: los commits y el
+  último tag se obtienen por API del remoto y el tag se crea en el remoto (y también localmente). Si
+  no, se usa `.repository-token` y todo se resuelve localmente.
+- `--update-changelog`: genera la entrada correspondiente en `CHANGELOG.md` y la commitea antes de

+- El tag se crea sobre el último merge (first-parent) de la rama. Si ese merge ya tiene un tag, no se
+  hace nada.
+- La versión se calcula a partir de los tipos de commit (CC) del último merge. Si ningún commit
+  implica un salto de versión, se avisa y el comando termina con código de salida 1.
+- Con más de un entorno configurado, cada rama versiona por separado con el nombre del entorno como
+  sufijo (por ejemplo, `v1.2.0-prod`). Con un solo entorno no se agrega sufijo.
+- Si el merge viene del entorno anterior (por ejemplo, `dev` a `test`), no se calcula una nueva
+  versión: se promueve la del entorno anterior cambiando el sufijo (si `dev` está en `v1.2.0-dev` y
+  `test` en `v1.0.0-test`, el nuevo tag es `v1.2.0-test`), sin importar los tipos de commit. Si ese
+  tag ya existe en el destino, el comando falla. En un pipeline, el merge se detecta por la rama
+  origen del PR; localmente, porque el merge trae tags del entorno anterior que el destino no tenía.
