 # CoinBrowser
+CoinBrowser is a tool for Freqtrade where the program writes pairs into text file to be used with spesific exchange.
+
+Data for this program is from CoinMarkedCap API. API key is needed for downloading the json file.
+The program creates coinhistory.db database if it is missing and uses the data from exiting json file.
+The database can be updated by checking UpdateDB and will it then upgrade from existing json file.
+Typically it is good to have the database few hours older than the json file as the DB should be few hours older for some calculations.
