-Python interface into my life
+Python interface into my life.
 
+This package deals with abstracting away various data sources and providing nice Python interface for them, also lets you define covenience functions.
+
+This might not necessarily be convenient for you to use, perhaps it's more of a concept of how you can organize and access your personal data.
+But it works for me so hopefully that would help you if you're struggling!
 
 # Setting up
+First you need to tell the package where to look for your data and external repositories, which is done though a python file named `my_configuration.py`, e.g.:
+```
+class paths:
+    class stexport:
+        repo       = /path/repos/stackexchange_export_repo
+        export_dir = /path/to/backups/stackexchange
+
+    class ghexport:
+        repo       = /path/repos/github_export_repo
+        export_dir = /path/to/backups/github
+```
+
+and pass the filename to the package:
+
 ```
 cp with_my.example with_my
 
-# edit path to your private configuration now:
+# specify path to your my_configuration.py:
 vim with_my
 ```
-TODO add instructions to try it?
 
 
 # Usage example
+If you run your script with `with_my` wrapper, you'd have `my` in `PYTHONPATH` which gives you access to your data from within the script.
+
+
 ```
 with_my python3 -c 'import my.books.kobo as kobo; print(kobo.get_todos())' 
 ```
+
+Also read/run [demo.py](demo.py) for a full demonstration of setting up Hypothesis.
