[[https://www.mediawiki.org/wiki/Extension:ContentTranslation|ContentTranslation extension]] should be converted to use manifest version 2 in its extension.json file.
In extension manifest version 1, documentation was made like this:
```lang=json
"config": {
"@ContentTranslationTargetNamespace": "Target namespace to publish articles. Values can be valid namespace ids. Example: 0 for Main, 2 for User namespace",
"ContentTranslationTargetNamespace": 0,
}
```
This documentation can now be done with "description" and "value" fields available in `manifest_version: 2` like this:
```lang=json
"config": {
"ContentTranslationTargetNamespace": {
"description": "Target namespace to publish articles. Values can be valid namespace ids. Example: 0 for Main, 2 for User namespace",
"ContentTranslationTargetNamespace": 0, "value": 0,
}
},
```
The maintenance script [[https://www.mediawiki.org/wiki/Manual:UpdateExtensionJsonSchema.php|maintenance/updateExtensionJsonSchema.php]] semi-automates this conversion and is recommended to be used
