## Summary

In this article, you learn how to enable the read mode ToC (Table of Contents) feature via config.properties for the e-paper issues in your app. 

***

## Preconditions

- Have an app created in Purple Manager
- Have a publication created in Purple Manager
- Have at least one issue created and content uploaded to your publication in Purple Manager
- Have read mode enabled for your app
- Have the config.properties doc, which you also use for importing content via SFTP-Upload, by hand

***

## Description

The enablement of the feature 'Read mode ToC' for e-paper issues in your app, is done by changing a value in your config.properties. The config.properties is the same document, which you also use for the import via SFTP-Upload for your e-papers with the Purple Importer. To do so, download the config.properties on your computer, overwrite the value and re-upload the config.properties via SFTP-Upload.

### read mode ToC disabled

The propertie 'readmodeToC' is per default set to 'false', so that it looks like this:

**readmodeToC=false** 

### read mode ToC enabled

If you want to enable the feature, you have to set the value to 'true', so that it looks like that:

**readmodeToC=true** 

:::hint{type="success"}
After setting the value in the config.properties to 'true' the read mode ToC is automatically generated and displayed for every issue that is imported after the enablement.
:::

:::hint{type="info"}
If you want to apply the changes also on the issues, that have been uploaded before the change, please re-import your existing content via your ordinary import procedure, after enabling the HTML ToC.
