 By using these metrics, you can determine if it's possible to use long polling in a given environment.
 
+## Compile/install
+
+The simplest way to use this program is (if you have go installed) is just to use the following command:
+```
+$ go install github.com/marcsello/longPollTester@latest
+```
+
+After that's complete you can use the `longPollTester` command from the commandline:
+
+```
+$ longPollTester
+2023/09/17 21:59:43 Starting HTTP server on :8080
+```
+
+If you don't have go installed, check out the Releases page, I have uploaded a pre-compiled binary version there.
+
 ## Usage
 
 Currently two command line options supported. Use -help to get more info:
 ```
+$ longPollTester -help
+Usage of longPollTester:
   -bind string
-        Address string to bind the server to (default ":8080")
+    	Address string to bind the server to (default ":8080")
   -timeout duration
-        Time for the server to return with 204 after, don't set it to never return (for intermediate timeout tests)
+    	Time for the server to return with 204 after, don't set it to never return (for intermediate timeout tests)
 ```
 
 When you start the server, it binds to `:8080` port by default. It accepts any URL and any method. Any new connections will be printed to the console.
 When a client connects a log line will be printed to stdout, and another one when the client disconnects. All requests given a unique (incremental) id, it is printed at the beginning of each log line between square brackets.
 
 ```
-$ go run main.go -timeout=60s
+$ longPollTester -timeout=60s
