+
+- [Requirements](https://github.com/alanEG/Gosna#Requirements)
+- [Installation](https://github.com/alanEG/Gosna#installation)
+- [Configuration file](https://github.com/alanEG/Gosna#configuration-file)
+- [Example usage](https://github.com/alanEG/Gosna#example-usage)
+    - [Normal_Usage](https://github.com/alanEG/Gosna#normal-Usage)
+    - [Dynamic_Usage](https://github.com/alanEG/Gosna#dynamic-Usage)
+
+## Requirements 
+
+   - [diff2html-cli](https://github.com/rtfpessoa/diff2html-cli)
+   - [js-beautify](https://www.npmjs.com/package/js-beautify)
+
+## Installation
+
+- [Download](https://github.com/alaneg/gosna/releases/latest) a prebuilt binary from [releases page](https://github.com/alaneg/gosna/releases/latest), unpack and run!
+
+  _or_
+- If you have recent go compiler installed: `go install github.com/alanEG/Gosna` (the same command works for updating)
+
+  _or_
+- `git clone https://github.com/alaneg/gosna ; cd gosna ; go build`
+
+Gosna depends on Go go1.18.1 or greater.
+
+
+## Configuration file
+
+Gosna doesn't work if you don't setup config file for save the urls and file names and other config   
+
+There are three ways the Gosna tool take config file from them 
+
+1 - `gosna_config` env
+
+2 - `~/.gosna_config.json`
+
+3 - `-config` option
+
+The defualt config file will be 
+
+```json
+{
+  "Config": {
+    "Is_first": false,
+    "Directory_work": "~/work/",
+    "Directory_result": "~/result/",
+    "Channel_use": "None",
+    "Channel": {
+      "Slack": null,
+      "Mail": {
+        "Tls": true,
+        "From": null,
+        "To": null,
+        "Host": null,
+        "Port": null,
+        "Email": null,
+        "Password": null
+      }
+    }
+  },
+  "Target": []
+}
+```
+
+`Is_first` Don't edit this will edit by the tool 
+
+`Directory_work` Edit this for the directory the tool will add the content of urls in it 
+
+`Directory_result` Edit this for the directory the tool will save html result in it 
+
+`Channel_use` Edit this for the channel the tool will use if it found change or use `None` if you need print the result in stdout channel available `[slack,mail]`
+
+- `channel`
+
+  - `Slack` slack webhook
+
+  - `Mail` Mail config
+
+## Example usage
+
+The usage examples below show just the simplest tasks you can accomplish using `gosna -h`. 
+
+```
+Enter Valid run type [check,add]
+Usage: ./change [options]
+   -run          Run type [add,check]
+   -timeout      Requests timeout (default 5)
+   -thread       Requests thread
+   -header       Requests header
+   -dynamic      Check dynamic (default false)
+   -config       Config file   (default ~/.gosna_config.json)
+   -no-color     Disable color
+```
+
+### Normal Usage
+
+There are two run type 
+- add
+- check 
+
+##### Example: `add` 
+Add for add the url to check it later 
+
+`cat url.txt | gosna -run add`
+
+Gosna will gets the url content then format it 
+
+Then save the content in directory work file 
+
+And add it to config file in Target json object  
+
+
+##### Example: `check`
+Chcek for check the url if there change 
+
+`gosna -run check`
+
+Gosna will gets the urls from config file then get the new content 
+
+And save it in the work directory then diff the new content with new conten
+
+### Dynamic Usage
+
+Here simply how check dynamic works when add
+
+1 - Send 5 request and save them responses in `tmp` directory
+
+2 - Get the the dynamic lines from the responses in the `tmp` directory   
+
+3 - Save the bigest response length 
+
+4 - Remove the dynamic lines from the file saved 
+
+5 - Add `true` in object is `Target[n].Status` for knowing the tool it is dynamic url 
+
+Here simply how check dynamic works when Check
+
+1 - Check the url is dynamic or not by `Target[n].Status`
+
+2 - Send request and remove the dynamic lines then save it in the file in work directory 
+
+3 - Diff the old content with new contnet 
+
+
+##### Example
+`cat urls.txt | gosna -run add -dynamic`
+
+##### Note
+Some time Dynamic option not working well 
+
+Let's imagen we need to monitor the `https://www.youtube.com/`
+
+Because the it printing diffrent line number in each request 
+
+The tool will printed this url in each check
