+# ISPConfig CLI
+Command line for ISPConfig remote user REST API using either smart functions or raw methods.
+
+## Getting Started
+This tool can be used and packaged stand alone, without ISPConfig itself. It is designed to have as few dependencies as possible.
+
+The script has two main modes: smart functions and raw methods.
+
+Raw methods simply wrap your JSON to the arbitrary method name you've given. As such, it works with any method, and makes properly formatted requests with curl. It is a handy tool for custom requests, testing, advanced scripting and integration work.
+
+Functions in turn are combinations of methods and checks that act more like an intelligent tool and does not require the user to understand JSON. This is handy for manual interaction or for scripting.
+
+> **Note:**
+Consider using -q for scripting, this will suppress everything but results and errors on the output.
+
+### Example function usage:
+    ispconfig-cli -f "dns_a_add example.com. www 192.168.0.2"
+
+    DNS zone example.com. has id 1.
+    DNS A www exists with id 228, updating...
+    Updated records: 1
+
+### Example method usage:
+    ispconfig-cli -m login -j credentials.json
+
+    {"code":"ok","message":"","response":"dc39619b0ac9694cb85e93d8b3ac8258"}
+
+> **Note:**
+The whole function has to be quoted as one due to how bash manages the command line arguments.
+
+### Config file
+The script uses an optional config file, allowing commands as short as above.
+
+These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for 
+notes on how to deploy the project on a live system.
+
+## Dependencies
