+### Hashing episode in python
+
+```python
+show = 'Rick and morty'.lower()
+season = 3
+for ep in range(1,10):
+	itemConcat = '.'.join([show, str(season), str(ep)])
+	hash_object = hashlib.sha1(str.encode(itemConcat))
+	hex_dig = hash_object.hexdigest()
+	print('%s : %s' % (hex_dig, itemConcat))
+```
+
+## What information should a hash index contain?
+For a show item, we would hash the name of the show, season number and episode number. What information do we want to keep about a item?
+
+#### Show episode
+ - The full name of the file.
+ - What show
+ - Season
+ - Episode
+ - [Name of episode]
+
+#### Movie
+ - The full name of the file
+ - Movie name
+ - Year
+
+#### Subtitles
+ - The full name of the file
+ - Language
+ - SDH?
+
+To move the item we just need the hash, and append all the other information. 
+
+## Scan vs Convert <a name='scan-vs-convert'></a>
+We are thinking there should be two main blobs. There should be one for the run cycle, when the new information is found, and one for the elements that have been handled. 
+
+Wait! This would mean that we need to move the information.

+## Looking up names for episodes
+The tmdb api [link](https://github.com/dbr/tvdb_api) can get extended information about a episode number. 
+
+```python
+import tvdb_api
+t = tvdb_api.Tvdb()
+episode = t['Rick and morty'][3][4] # get season 1, episode 3 of show
+print(episode['episodename']) # Print episode name
+```
+
+A large stall in the system would be to do a http call to the tvdb api to get the episode name every time we run seasoned. What we could do is when we find a episode from a series we can look for and cache all episode names that are that season for the series. 
+
+This can be saved in the blob in the hash location for the episode. This means we can make a hash table insertion without having the episode yet.
