+# Real Time API (RTAPI) Latency Testing Tool
+
+This tool measures the latency response of a series of API endpoints and creates a PDF report with an HDR histogram of all API endpoints.
+
+## How to use
+
+`rtapi` takes either a JSON file or a JSON string containing endpoint data and query parameters (optional), queries each endpoint using the query parameters (or default query values if no parameters have been specified), and outputs a PDF report containing all the endpoint query results plotted in an HDR histogram.
+
+```
+$ ./rtapi -h
+NAME:
+    Real time API latency analyzer - Create a PDF report and HDR histogram of Your APIs
+
+USAGE:
+    rtapi [global options] command [command options] [arguments...]
+
+VERSION:
+    v0.0.1
+
+COMMANDS:
+    help, h  Shows a list of commands or help for one command
+
+GLOBAL OPTIONS:
+    --file value, -f value    Select a JSON file to load
+    --data value, -d value    Pass API parameters directly as a JSON string
+    --output value, -o value  PDF report file name
+    --help, -h                show help (default: false)
+    --version, -v             print the version (default: false)
+```
+
+## Sample JSON
+
+```json
+[
+  {
+    "target": {
+      "url": "https://www.example.com",
+      "method": "POST",
+      "body": "{\"id\":\"0\"}",
+      "header": {
+        "Content-Type": [
+          "application/json"
+        ]
+      }
+    },
+    "query_parameters": {
+      "threads": 2,
+      "max_threads": 2,
+      "connections": 12,
+      "duration": 10,
+      "request_rate": 500
+    }
+  }
+]
+```
+
+## Default Query Values
+
+The default query parameters closely follow the default query parameters found in [`wrk2`](https://github.com/giltene/wrk2).
+
+```
+"threads": 2
+"max_threads": 2
