# Modify Families
Smart Browser utilizes modification files to create a description of how families will have to be modified.
The process has two steps:
1. Modification file creation
2. [Running the described modifications](/design-data-management-and-exchange/smart-browser/run-modifications.md)
{% hint style="info" %}
Changes to families will apply only after the **'Run Modifications'** command has been applied.
{% endhint %}
### Creating Modification task
Select one or multiple (Ctrl + left-click) families in your library that you want to modify. Right-click the selection, and choose the option '**Modify Families**'.
You will be prompted to enter the modification name.
After entering the modification name, you need to enter additional information that will be accessible later:
1\) The person doing the modification
2\) A short description of the modification
3\) Notes. Any additional information regarding the planned modifications.
{% hint style="info" %}
Smart Browser will later automatically fill the Notes with the information about the changes to be made.
{% endhint %}
Once the modification task file is created, it may be closed and opened at any time to continue filling or to review theb modification tasks. To open an already-created modification file, click '**Modify Families**' and select the required modification file.
To add more families to a previously-created modification file, select the required families and in the right-click menu, select 'Add Families to be Modified'. Then select to which modification file you would like to add those families.
**Family Modifications**
In the right-click menu, you can modify selected values or parameters. After the modification task is created, either the cell or the cell value will change color according to the Legend View.
