+## Custom Documentation
+
+You can add user-defined documentation to the existing effect documentation by placing .txt files in the 'customDocs' directory. When switching effects in the UI, the plugin loads `customDocs/<effect-name>.txt` (if present) and prepends it with a separator before the original text. For example, to add documentation to the effect `ToTape7`:
+
+- Choose "Show Config Dir" from the menu to navigate to the config directory.
+- Create the file `customDocs/ToTape7.txt`.
+- Add "This is my own text" to the file and save.
+- In the plugin UI, switch away from the ToTape7 effect, then switch back. This forces the text to reload.
+
+You'll now see:
+
+```
+This is my own text
+
+#----------------------
+
+This is the original text...
+```
+
+Note:
+
+- Filename casing is important on Linux (and sometimes on Mac). Use `ToTape7.txt`, not `totape7.TXT`.
