 ## Planned Features  
 
-- Right-hand side prompt: Implementing this is a challenge on non-`zsh` shells  
-- Configuration file  
+- **Right-hand side prompt**: Challenging to implement on non-zsh shells.   
+- **Configuration file**  
   - Choose only the components you need  
   - Change appearance  
-    - symbols and texts  
-	- colors  
-	- order and position  
-	- Etc.  
-  - User-defined components  
-    - Static symbols or strings  
-	  - Shell symbol  
-	  - Host name  
-	  - Etc.  
-    - Dynamic components by running custom commands  
-	  - Time & date  
-	  - More `git` information  
-	  - System stats  
-	  - Basically, anything you like  
+    - Symbols and text  
+	- Colors  
+	- Order and position    
+  - Custom components  
+    - Static: Shell icon, Host name, etc.  
+    - Dynamic: Time &date, system stats, or any custom commands  
 
 ## Current Limitations  
 
-- Not user-configurable, yet - any changes in the current stage require hard-coding.  
-- Exit code of the last command requires to be passed as a command-line argument.  
+- **Hard-Coded Configuration**: User customization is not available yet. 
+- **Exit Code Requirement**: Must pass the last command’s exit code as a command-line argument.

 ## Usage  
 
-The binary needs to be in your `$PATH`. Place it somewhere like `/usr/bin/`, or add the appropriate path to the `$PATH` variable.
-The configuration depends on the shell, and the file location can vary according to your distro. Please consult the documentations or forums of your shell for more accurate information.  
+Configuration varies by shell, and the file location varies by distro. Consult your shell's docs or community resources for details. Note that the exit code of the last command(usually `$?` variable) must be passed as a command-line argument.

 ## Changes since the last version
  - **Updated Output String Type:** Improved compatibility with other shells.  
  - **Revamped Indicator Symbols:** Enhanced the visual aspect of the prompt.  
- - **Removed Shell Symbol:** Determining the shell is practically not possible.  
+ - **Removed Shell Icon:** Determining the shell is practically not possible.  
  - **Conditional Component Inclusion:** A first step towards user-configuration expected in future versions.  
  - **Code Improvements:** readability and performance  
    - **Refactoring:** Modular structure for better readability and maintenance.

+## Why this project?  
+
+- **Efficiency**: Avoids repeated invocation of multiple binaries like `tr`, `grep`, `echo`, `git`, `sed`, etc., which would otherwise be used dozens of times in shell scripts just to generate a colored string.  
+- **Universality**: Eliminates the need to write separate scripts in different shell languages for various shells.  
+- **Learning Rust**: Serves as a fun and practical project to learn and apply Rust programming skills.
