 ## What does this project do?
 
-This project is a lightweight user-friendly software which filters logs. You give him a log file and filters and it displays for you the lines where your filters appear.
+This project is a lightweight user-friendly software which filters logs.
 
 **This is a re-write of my previous project** [Lyaaaaa's Logs Filter](https://github.com/Lyaaaaaaaaaaaaaaa/Lyaaaaa-s-Logs-Filter). This aims at being more portable, faster and easier to maintain. 
 
+## Functionalities 
+
+- **Efficiently search through logs** - ctrl+f isn't efficient for big files
+- **Start by casting a wide net** - By setting `Search for all filters` to off
+ you can fetch all the lines where at least one filter appears.
+- **Sharpen your search** - By setting `Search for all filters` to on you can
+ fetch the lines where all your filters appear.
+- **Disable/Enable case sensitivity**
+- **See in real time the statistics of your search** - The number of lines 
+searched and the number of lines matching your filters are displayed in the top
+right-hand corner of the application.
+
 ## Why is this project useful?
-It is more efficient and more readable for sizeable files. Ctrl+f is limited when you need a clear and readable output. Moreover, this project accepts multiple filters. Not everyone has knowledge in Linux/Windows terminal. The software comes with a simple interface usable by anyone.
