+Configuration
+---
+
+A very small amount of configuration is possible by creating a file called `leech.json` in the project directory. Currently you can define login information for sites that support it.
+
+Example:
+
+```
+{
+    "logins": {
+        "QuestionableQuesting": ["username", "password"]
+    }
+}
+```
