-# pancloud-nodejs
-Palo Alto Networks Application Framework NodeJS SDK
+# Palo Alto Networks Cloud NodeJS SDK
+NodeJS idiomatic SDK for the Palo Alto Networks Application Framework.
 
-## EXPERIMENTAL
+The Palo Alto Networks Cloud NodeJS SDK (or pancloud for short) was created to assist developers with programmatically interacting with the Palo Alto Networks Cortex Framework.
+
+The primary goal is to provide full, low-level API coverage for the following Application Framework services:
+
+* Logging Service
+* Directory Sync Service
+* Event Service
+
+The secondary goal is to provide coverage, in the form of helpers, for common tasks/operations. (Log/event pagination, OAuth 2.0 and token refreshing ...)
+
+# Quick Starting
+1. Install `pancloud` in your project as a dependency
+```$ npm install pancloud```
+2. Use the `autoCredentials()` function to instantiate a `Credentials` object based on your environmental variables
+    * _Option 1_: Set the variable `PAN_ACCESS_TOKEN` to retrieve a `Credentials` instance (valid to interface with a datalake as long as the access token is not expired / no auto-refresh available)
+    * _Option 2_: Set the variables `PAN_CLIENT_ID`, `PAN_CLIENT_SECRET` and `PAN_REFRESH_TOKEN` to instantiate a memory-based credentials provider and retrieve a `Credentials` object bound to the datalake for which the provided refresh token was issued (auto-refresh available)
+    * _Option 3_: Set the variable `PAN_DEVELOPER_TOKEN` to retieve a `Credentials` object that will leverage your API Explorer tenant to issue access tokens on your behalf
+3. Instantiate a `LoggingService` object using the `Credentials` object you obtained in the step 2
+4. Perform a query using the `query()` method of your `LoggingService` object.
+
+## Quick Starting Examples
+create a file named `index.js` in your project forder with the following content
+```
+const pancloud = require('pancloud');
+pancloud.autoCredentials()
+    .then(credentials => pancloud.LoggingService.factory(credentials))
+    .then(loggingService => loggingService.query({
+        query: "SELECT * FROM panw.dpi WHERE subtype='dhcp' LIMIT 1",
+        startTime: 0, // 1970
+        endTime: 2000000000, // 2033
+        maxWaitTime: 30000 // wait up to 30 seconds for the query to complete
+    }))
+    .then(jobResult => console.log(JSON.stringify(jobResult, undefined, ' ')))
+```
