+## Comic Source List
+
+Venera can display a list of comic sources in the app.
+
+You can use the following repo url:
+```
+https://git.nyne.dev/nyne/venera-configs/raw/branch/main/index.json
+```
+The repo is maintained by the Venera team.
+
+> The link is a mirror of the original repo. To contribute your comic source, please visit the [original repo](https://github.com/venera-app/venera-configs)
+
+You should provide a repository url to let the app load the comic source list.
+The url should point to a JSON file that contains the list of comic sources.
+
+The JSON file should have the following format:
+
+```json
+[
+  {
+    "name": "Source Name",
+    "url": "https://example.com/source.js",

+Only one of `url` and `filename` should be provided.
