## Quickstart

Installing UStore is a breeze, and the usage is about as simple as a Python `dict`.

```python
$ pip install ukv
$ python

from ukv import umem

db = umem.DataBase()
db.main[42] = 'Hi'
```

We have just create an in-memory embedded transactional database and added one entry in its `main` collection.
Would you prefer that data on disk?
Change one line.

```python
from ukv import rocksdb

db = rocksdb.DataBase('/som
