+
+Configuration
+=============
+
+You can change the limit applied to the text from Settings > Technical > User Interface > Text Limits
+
+If the limit is set to 0, no limit will be applied
+
+Usage
+=====
+
+To use it in QWeb views, you need to assign the text widget in t-options if the field does not use it by
+default, along with text_limit and the name of the limit to be applied.
+
+.. code:: xml
+
+  <span t-field="name" t-options="{'text_limit': 'Journal Limit'}" />
+
+Known issues / Roadmap
+======================
+
+For now, the limit is only applied to QWeb views, but the intention is to apply it to all views once the corresponding
+option is added.
