 The only static-file server you'll ever need!
 
 ### Features:
-- Logging
-- Basic-Auth _(optional)_
+- Logging - [`winston`](https://www.npmjs.com/package/winston)
+- Basic-Auth - [`basic-auth`](https://www.npmjs.com/package/basic-auth)
 - Custom 404 page
 - Optimum Compression - [`compression`](https://www.npmjs.com/package/compression)
 - Security checks / headers - [`helmet`](https://www.npmjs.com/package/helmet)
 - Opbeat error-reporting - [docs](https://opbeat.com/docs/articles/get-started-with-express/)
+- Whitelist IP Addresses - [`express-ip-access-control`](https://www.npmjs.com/package/express-ip-access-control)
+- Directory Listing - [`serve-index`](https://www.npmjs.com/package/serve-index)
 
-### Usage / Configuration
+### Usage
 ```bash
-tstatic <directory>
+  tstatic <dir> [options]
+    
+  -h --help     Show this screen.
+  --version     Show version.
+  -p <port> --port=<port>  Port to listen on.
+  -b <auth> --basic-auth=<auth>   Enable basic-auth.
+  -i <ips> --ips=<ips>  Allowed IP addresses.
+  -l --list-dir  List Directory.
+  --opbeat  Enable Opbeat.
+  -o --open  Open in browser after start.
+ 
 ```
-`directory` is where your static files are.
+`dir` is where your static files are.
 
-404 errors will return with `<directory>/.404.html`, with status code 404. If this file doesnt exist, plain error page will be shown.
+404 errors will return with `<dir>/.404.html`, with status code 404. If this file doesnt exist, the default error page will be shown.
 
 
-#### Environment
-Make sure to set `NODE_ENV` to `production`!
+### Configuration
 
-`PORT`: The port you want the server to listen on. Default: `5000`.
+##### `port`
+The port for the server to listen on. Currently supports plain HTTP only
 
-`BASIC_AUTH_USERNAME` / `BASIC_AUTH_PASSWORD`: Credentials for built-in basic auth
+##### `basic-auth`
+Enable basic-auth for all paths. Currently only supports single credentals.  
 
-Opbeat middleware is configured using documented variables [here](https://opbeat.com/docs/articles/opbeat-for-nodejs-api/#appid). _Requires production `NODE_ENV`!_
+Format:`-b username:password`
 
+##### `ips`
+IP addresses that are allowed to connect to the server.
+
+Format: `-i 192.168.1.100,192.168.1.101`
+
+##### `list-dir`
+Enables directory listing. Allow browseing
+
+##### `opbeat`
+Enable opbeat error reporting. `--opbeat` only enables this, configuration is done using [environment varables](https://opbeat.com/docs/articles/get-started-with-express/#appId).
+
+##### `open`
+Open the server in the browser one started. It will open in your default browser, and use url `http://0.0.0.0:<port>`.
