+## What does this API do ?
+This api as of now provides a function which takes in a lits of 'LABELS' of prometheus
+and returns the corresponding result_sets in a list.
+
+For eg:
+If the labels is
+
+```
+LABELS = ['irate(collectd_cpufreq{exported_instance="otconap7",cpufreq="1"}[2m])']
+```
+
+The return is:
+
+```
+[{'metric': {'cpufreq': '1',
+ 'endpoint': 'collectd-prometheus',
+ 'exported_instance': 'otconap7',
+ 'instance': '172.25.103.1:9103',
+ 'job': 'collectd',
+ 'namespace': 'edge1',
+ 'pod': 'plundering-liger-collectd-wz7xg',
+ 'service': 'collectd'},
+ 'value': [1559177169.415, '119727200']}]
+```
+
+## How to use this API ?
+
+```
+1. Copy the directory 'promql_api' to your working directory.
+```
+
+```
+2. Import the API function: query
+from promql_api.prom_ql_api import query
+```
+
+```
+3. have a global or local variable as 'LABELS'
+LABELS = ['irate(collectd_cpufreq{exported_instance="otconap7",cpufreq="1"}[2m])']
+```
+
+```
+4. Store the result set in a list:
+list_of_result_sets = query(LABELS)
+```
+
+## Troubleshooting tips
+
+* Check the sample file - sample_promql_query.py in the repo ( sample-apps/m3db_promql)
+* Make sure the file "__init__.py" is present in promql_api directory after you copy the directory.
+* Make sure environment variables like "DATA_ENDPOINT" are correctly set.
+* Logs are generated in the directory where the query function is called.
+* sample log file - promql_api.log
