 - Frontend, powered by _HTML_, _CSS_ & last but not least _Javascript_ _( yeah not using any UI framework )_
 - Audio-Video playing is done using HTML5 **\<video>** element, which can play _mp4_ & _webm_ video(s) generally
 ## how can I use it ?
-- Simply fork this repo & clone it in you machine
-- Make sure you've installed _Dart SDK_ & you're on _*nix_ platform
-- Because I gonna use _systemd.service_ to keep this streaming service alive in background, always, even after system restarts it'll auto start itself
-- You need to make sure, you've _~/Videos/_ directory present on your system, cause we'll read from that directory _( every 30 minutes )_, to ensure all _mp4_ & _webm_
-videos, present in aforementioned directory, are listed in movie playlist
-- Start streaming server, which will be available via port 8000
+- If you're on _Linux_, then I've already compiled **streamZ** into an executable binary _( using dart2native compiler )_, which can be simply run on any Linux Machine, cause that executable binary is one self-sufficient one _( but not yet platform-agnostic, which will change is near future )_.
+- Then download [_this_](.) compressed file, and unzip it into a suitable location on your machine.
+- You'll get a directory tree like below
 ```shell script
-$ cd bin # assuming you're already at root of project directory
-$ dart main.dart
-```
-- Consider using _Ahead Of Time_-compiled version _( at production )_, for better performance
-```shell script
-$ dart2aot main.dart main.dart.aot // compilation
-$ dartaotruntime main.dart.aot
+$ cd
+$ unzip streamZ.zip # unzipping it
+$ cd streamZ # getting into actual directory
+$ tree -h

 ```
-- If you're having a lot of traffic, consider using multiple Isolates to handle traffic efficiently
+- Now get into `./final` directory & run executable binary, which will start a media streaming server on _http://0.0.0.0:8000_
 ```shell script
-$ dartaotruntime main.dart.aot 2 // using two Isolates
-$ dartaotruntime main.dart.aot n // using n Isolates, n >= 1
+$ cd final
+$ ./streamZ # running movie steaming server
+[+]streamZ_v1.0.0 listening ( streamZ0 ) ...
+
+[+]streamZ_v1.0.0 listening ( streamZ1 ) ...
+
 ```
-- Now you can simply use this streaming service by opening `http://ip-addr-server:8000/`, on any device's browser present in LAN
-- For using service from same machine, simply use `http://localhost:8000/` from your favourite browser
-- Deploying via _systemd.service_, to be explained in a blog post, to be published soon
+- To check, open browser from same machine & type _http://localhost:8000_ into address bar, you'll get a list of all movies present under _~/Videos/_ directory, which is default video storing directory on _Linux_ running machines.
+- You can also access this streaming service by opening _http://x.x.x.x:8000/_,on any device's browser, present in LAN
+- Where `x.x.x.x` is nothing but Local IP Address of machine, running **streamZ**

+- If you want to dig deeper, simply fork this repo & clone it in you machine
+- Make sure you've installed _Dart SDK_ & you're on _*nix_ platform
+- Because I gonna use _systemd.service_ to keep this streaming service alive in background, always, even after system restarts it'll auto start itself
+- You need to make sure, you've _~/Videos/_ directory present on your system, cause we'll read from that directory _( every 30 minutes )_, to ensure all _mp4_ & _webm_ videos, present in aforementioned directory, are listed in movie playlist
+- If you're having a lot of traffic, consider using multiple Isolates to handle traffic efficiently. Just update `int count = 2;` on line 100 of `./bin/main.dart` to whatever value you intend to use, that many Isolate(s) will be created on boot, they'll distributedly handle whole traffic coming in.
+- I've also written one systemd unit file, which can be used for deploying **streamZ**, so that it'll keep running always _( autostart after failure & system boot )_
+- Consider using so, by modifying this systemd unit [file](./systemd/streamZ.service)
 ## how does it look like ?
