 # CoingeckoClient
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/coingecko_client`. To experiment with that code, run `bin/console` for an interactive prompt.
+This is my first gem and the idea was to develop a super simple and lightweight client to connect with Coingecko API. 
+Keep in mind that this is by no means the oficial gem from Coingecko, it is a pet project that I have interest in keeping it working!
+I published it with the methods that I need for another project, but I'll keep on adding more methods to interact with the rest of the API. Any comments, sugestions, Pull Requests, feel free to contact me.

 ## Usage
 
-TODO: Write usage instructions here
+The available methods are:
+
+
+* Check if API is up:
+```
+2.7.0 :026 > CoingeckoClient::Client.ping
+ => {"gecko_says"=>"(V3) To the Moon!"} 
+```
+
+* List coins
+
+List all supported coins id, name and symbol (no pagination required)
+
+```
+2.7.0 :027 > list=CoingeckoClient::Client.coins_list
+2.7.0 :028 > list.count
+ => 7631 
+2.7.0 :029 > list.first
+ => {"id"=>"01coin", "symbol"=>"zoc", "name"=>"01coin"} 
+```
+* Supported_vs_currencies<br>
+
+Get list of supported_vs_currencies.
+```
+2.7.0 :002 > list = CoingeckoClient::Client.supported_vs_currencies
+2.7.0 :003 > list.count
+ => 55 
+2.7.0 :004 > list.first
+ => "btc" 
+```
+
+* Current price <br>
+Get the current price of any cryptocurrencies in any other supported currencies that you need.
+```
+CoingeckoClient::Client.price(<coin>,<currency>)
+```
+For example:
+```
+2.7.0 :016 > CoingeckoClient::Client.price('bitcoin','usd')
+ => 9246.4 
+```
+
+* Historical market data
+To get the historical market data(price, market cap and trade volume) of a given coin, you would use:<br>
+<sub><strong>
+Coingecko's note about this API call: Minutely data will be used for duration within 1 day, Hourly data will be used for duration between 1 day and 90 days, Daily data will be used for duration above 90 days.
+    </sub></strong>
+
+```
+CoingeckoClient::Client.coin_history(<coin>,<currency>,<number_of_days>)
+```
+For example:
+```
+CoingeckoClient::Client.coin_history('bitcoin','usd','7')
+ => {"prices"=>[[1593511281310, 9161.947854845832], ..., [1594113061000, 9247.986673179646]], market_caps"=>[[1593511281310, 168752424140.90503], ..., [...,...]], , "total_volumes"=>[[...]]}
+```
+
+* Market data from coins: <br>
+Use this to obtain all the coins market data (price, market cap, volume)
+
+```

 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
