# Remove, Edit and Clone Knowledge
### Remove Knowledge
Sometimes you need to remove the knowledge from a system when it’s no longer needed. In the FAQ Knowledge feature, you can ***remove knowledge manually*** one by one or ***remove all knowledge based on modules***.
For example, when you need to delete some knowledge contained in the chit-chat module, you need to select the knowledge that you will delete by searching for the knowledge based on the title or question knowledge, then clicking the ***remove*** icon. Then, you will prompts to confirm the remove request, click *‘**Yes***‘ to proceed remove knowledge, or you can click ‘***No***‘ to return to the list FAQ Knowledge page.
However, if you want to delete all the knowledge contained in the chit-chat module, you can click the ***remove*** icon on the module. Then, you will prompts to confirm the remove request, click ‘***Yes***‘ to proceed remove module, or you can click ‘***No***‘ to return to the FAQ Knowledge page.
Or you can also re-save some of the knowledge you still need to another knowledge module before you actually delete that module.
### Edit Knowledge
Sometimes you need to change the data from the system when it is possible because of data changes or there's an error in data.
Go to ***Bot Settings*** and click the ***FAQ Knowledge*** menu, then select/search knowledge that you want to edit. Select the edit button '
' on the right, and edit the knowledge you want.
When you have finished, click ***'Save Knowledge'*** to save the modified knowledge.
### Clone Knowledge
If you need to create a Module with a knowledge content that is almost the same or even the same as an existing module, you can use the Clone Module feature.
This feature will duplicate the previously created Module. For example, if you have previously created the "About Bella" Module and you have a new need to create a knowledge module from a different Bot, then you can try duplicating the Module by selecting the clone button '
' on the right of the Module name.
Once clicked, you will be asked to fill in the name of the new module, and you can fill in "About Mella" and click the clone button.
The module has been duplicated successfully. Furthermore, you can add or change knowledge as needed.
