+---
+
+Moved catalog processor and provider disabling and priorities under own config objects.
+
+This is due to issue with some existing providers, such as GitHub, using array syntax for the provider configuration.
+
+The new config format is not backwards compatible, so users will need to update their config files. The new format
+is as follows:
+
+```yaml
+catalog:
+  providerOptions:
+    providerA:
+      disabled: false
+    providerB:
+      disabled: true
+  processorOptions:
+    processorA:
+      disabled: false
+      priority: 10
+    processorB:
+      disabled: true
+```

+### Processor configuration
+
+You can configure processors under the `catalog.processorOptions` key. You can define
+options for each processor by its name. With the processor options you can disable
+a processor or set its priority.
+
+```yaml
+catalog:
+  processorOptions:
+    processorName:
+      disabled: false # Defaults to false
+      priority: 100
+```
+
+The priority is a number defining the order in which processors are executed. The lower the number,
+the higher the priority. The default priority is `20`.
+
+## Provider configuration
+
+It's possible to also disable entity providers using the config. You can configure providers
+under the `catalog.providerOptions` key. The key is the provider name.
+
+```yaml
+catalog:
+  providerOptions:
+    providerName:
+      disabled: true
+```
