 # Mango transaction scraper
 
-### Run
+Collects and stores transactions made by the Mango program and Oracle program (used by the Mango program).
+Does so by
+* fetching new signatures from the program (getConfirmedSignaturesForAddress2)
+* using those signatures to fetch transactions (getParsedConfirmedTransaction)
+* parsing details of the transactions (looking at the token accounts and also transaction logs)
+* stores details into a postgres database
+
+## Run
+As the app requires the postgres database as a backend - it is not self contained.
+However, if the postgres db is setup:
 ```
 yarn install
 yarn start
 ```
+
+## Configuration
+Configuration is handled via environmental variables.
