+MTGA tools & set data for python. Original cardset generated with MTGJSON and scryfall,
+with initial set of  MTGA grpId's collected by Fugi & Spencatro.
+(Now we just use the data already present in your MTGA installation.)
 ## Installation
-
 `pip install mtga`
-
 or
-
 `python setup.py install`
-
 ## Usage
-
 ```python
 from mtga.set_data import all_mtga_cards
-print(all_mtga_cards.find_one("63773"))
-# <Card: 'Torrential Gearhulk' ['Blue'] KLD 63773>
+print(all_mtga_cards.find_one("Mangara"))
+# <Card: 'Mangara, the Diplomat' ['White'] M21 71809>
+print(all_mtga_cards.find_one(71809))
+# <Card: 'Mangara, the Diplomat' ['White'] M21 71809>
+print(all_mtga_cards.find_one("71809"))
+# <Card: 'Mangara, the Diplomat' ['White'] M21 71809>
 ```
-
 ## Deploying
-
 Because I always forget:
-
 ```bash
 python setup.py sdist bdist_wheel
+twine check dist/*  # check for readme issues (e.g. line endings MUST BE LF, not CRLF lol)
 twine upload dist/MTGA-<version>*
 ```
