+## Before requesting a new feature
 
-# Current state:
+* A lot of features are not enabled by default. Please try `fastfetch --list-modules` and `fastfetch -c all.jsonc` to see if it has been supported
+* Fastfetch supports `Command` module, which can be used to grab output from a custom shell script. Please check if it fits your needs
 
-# Wanted state:
+```jsonc
+// ~/.config/fastfetch/fastfetch.jsonc
+{
+    "modules": [
+        {
+            "type": "command",
+            "text": "/path/to/your/script",
+            "key": "Feature Title"
+        }
+    ]
+}
+```
