+# Go SoftPack Analytics
+
+This package provides a simple server that listens on a port for simple analytical information, to which it adds simple metadata and prints.
+
+## Usage
+
+The server takes the following arguments:
+
+|   Argument   |   Default   |  Description               |
+|--------------|-------------|----------------------------|
+| -p           | 1234        | The TCP port to listen on. |
+| -o           | - (stdout)  | The file to print to.      |
+
+## Output
+
+The generated file will be a TSV with the following fields:
+
+|   Field   |   Description                                                       |
+|-----------|---------------------------------------------------------------------|
+| Time      | Human readable timestamp of the format: YYYY-MM-DD HH:mm:ss         |
+| Path      | The path of the executable that was passed to the analytics server. |
+| Username  | The user the ran the executable.                                    |
+| IP Address| The IP Address on which the executable was ran.                     |
+
+## Sending Data
+
+This server can recieve information in a very simple format which consists of a username and an executable path, seperated by a null byte.
+
+An example usage is below:
+
+```bash
+{
+        (echo -e "$USER\0$0" > /dev/tcp/server-domain/1234 2> /dev/null) &
+} 2> /dev/null
+```
+
+…where server-domain is the domain name that the analytics server is running on and 1234 is the port it is listening on.
