 This little script allows simple interaction between `taskwarrior` and a `jrnl` file.
 It parses the `jrnl` file and logs accomplished tasks in `taskwarrior`.

+To accomplish this it borrows a little from the [todo.txt](http://todotxt.org/) syntax --- 
 namely the idea of (A) (B) (C) prioritization and `x task done syntax` 
 (i.e. starting a line with `x ` means it represents an accomplished task).
 
+## Usage
+
+Point the file to your `jrnl` file (ideally it needs to be a single file) and 
+set the syntax which declares a `todo` entry within it.
+
+```bash
+./open-todo-txt.py -f ~/.local/share/jrnl/journal.txt -b 'todotxt'
+```
+
+The commandline above sets the script to work on a specific `jrnl` file
+and only work on entries which have exactly `todotxt` as their title.
+The settings above are also the default settings of the script.
