 # JustBetter OptimizeFlatTables
 
-This module checks the product attributes with backend type `varchar` used in the flat table and determines the length of the column. Instead of taking the default value of `255`.
+In Magento 2 when you want to index many text fields to the flat tables you could run into the `Syntax error or access violation: 1118 Row size too large (> 8126). Changing some columns to TEXT or BLOB may help.` error.
 
-If you have a lot of product attributes used in the flat table it could result in problems with the "Row Size being too large".
+The reason being every field taking up length for 255 characters while this is often not used.
+
+This module aims to reduce the chance of this happening by checking the product attributes with backend type `varchar` used in the flat table, and determine the actual length of the column. Instead of taking the default value of `255`.
+
+## Installation
+
+Run
+
+```shell
+composer require justbetter/magento2-optimizeflattable
+```
+
+After enabling the module your problems indexing to the flat tables should be resolved!
