+Battery Indicator
+=================
+
+This is a simple battery indicator. Depending on the value of `from_acpi`
+it either uses the system command `acpi` or processes data from the `/proc`
+filesystem. To use it place the following code in your `wmiirc_local.py` file.
+Please note, that monitors in wmii are sorted
+alphabetically by their function names, so you might want to change the name as
+you see fit.
+
+The `trem` function is a helper function used to convert seconds to the format
+`hh:mm:ss`. `info_path` and `state_path` point to virtual files containing relevant
+information regarding the battery.
+
+

+Memory Usage Indicator
+======================
+
+This is a simple memory usage indicator based on information obtainable from
+the `free` system command.
+
+It was written to work with wmii-3.9 and higher. To use it you have to put it
+in your `wmiirc_local.py` file. Please note, that monitors in wmii are sorted
+alphabetically by their function names, so you might want to change the name as
+you see fit.
