 # DataForSEO SERP API Python Client
 
+A simple Python client example to send requests and get results from [DataForSEO SERP API](https://dataforseo.com/apis/serp-api).  
+
 ## Setup
 
+1. Clone this repo:  
+
+    $ git clone git@gitlab.com:databulle/dataforseo-serp-api-python-client.git  
+    $ cd dataforseo-serp-api-python-client  
+
+2. (Optional) Setup a new [pyenv](https://github.com/pyenv/pyenv) virtual environment:  
+
+    $ pyenv virtualenv 3.7.0 dataforseo  
+    $ pyenv local dataforseo  
+
+3. Get your credentials from DataForSEO:  
+
+Go to [the API dashboard](https://app.dataforseo.com/api-dashboard) and get your `API Login` and `API Password`.  
+
+4. Create you `config.ini` file:  
+
+Copy the sample config file:  
+
+    $ cp config.sample.ini config.ini  
+
+Edit the new file and fill in your login and password  
+
+5. That's all!  
+
+### Sandbox  
+
+If you want to test the API, you can simply edit the `client.py` file and replace on line 7:  
+
+    domain = "api.dataforseo.com"  
+
+With:  
+
+    domain = "sandbox.dataforseo.com"  
+
+The sandbox API lets you post as many requests as necessary to try your setup, and can send you dummy data.  
+Remember to switch it back when things get real ;)  
+
+
 ## Usage
 
 ### 1. Post tasks
 
 ### 2. See if tasks are ready
 
+This step is not required, but will show you how many of your requests have been processed and are available for download.  
+Simply run:  
+
+    $ python tasks_ready.py  
+
+
+
 ### 3. Get results
