+# Dates & Periods
+
+The module is shipped with a ``date`` module for manipulating time periods and 
+converting dates between different formats. Th  *period* function can be use 
+to create ``Period`` instanc.::
+
+```{code-cell} ipython3
+import ccy
+p = ccy.period("1m")
+p
+```
+
+```{code-cell} ipython3
+p += "2w"
+p
+```

+p += "3m"
+p
+```

+
+## Getting Started
+
+* installation
+```bash
+pip install ccy
+```
+* display currencies
+
+```{code-cell} ipython3
+import ccy
+import pandas as pd
+df = pd.DataFrame(ccy.dump_currency_table())
+df.head(80)
+```
+
+## Main Usage
+
+```{code-cell} ipython3
+import ccy
+eur = ccy.currency("aud")
+eur.printinfo()
+```
+
+a currency object has the following properties:
+* *code*: the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) three letters codee.
+* *twoletterscode*: two letter crg.
+* *default_country*: the default [ISO 3166-1 alpha_2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) country code for the currency.
+* *isonumber*: the ISO 4217 number.
+* *name*: the name of the currency.
+* *order*: default ordering in currency pairs (more of this below).
+* *rounding*: number of decimal places
+
++++
+
+## Currency Crosses
+
+
+You can create currency pairs by using the ``currency_pair`` functn::
+
+```{code-cell} ipython3
+c = ccy.currency_pair("eurusd")
+c
+```
+
+```{code-cell} ipython3
+c.mkt()
+```
+
+```{code-cell} ipython3
+c = ccy.currency_pair("chfusd")
+c
+```
+
+```{code-cell} ipython3
+c.mkt()  # market convention pair
+```
+
+## cross & crossover
+
+Some shortcuts:
+
+```{code-cell} ipython3
+ccy.cross("aud")
+```
+
+```{code-cell} ipython3
+ccy.crossover('eur')
+```
+
+```{code-cell} ipython3
+ccy.crossover('chf')
+```
+
+```{code-cell} ipython3
+ccy.crossover('aud')
+```
+
+Note, the Swiss franc cross is represented as 'USD/CHF', while the Aussie Dollar and Euro crosses are represented with the USD as denominator. This is the market convention which is handled by the order property of a currency object.
+
++++
+
+## Eurozone
+
+The euro area, commonly called the eurozone (EZ), is a currency union of 20 member states of the European Union (EU) that have adopted the euro (€) as their primary currency and sole legal tender, and have thus fully implemented EMU policies.
+
+```{code-cell} ipython3
+ccy.eurozone
+```
+
+```{code-cell} ipython3
+ccy.print_eurozone()
+```
