 # go-censorword
-
-go-censorword is a lightweight library for detecting profanities in Go string.
-
+go-censorword is a lightweight and easy-to-use tool that allows you to detect and filter out profanity words from your text-based content. Whether you're building a social media platform, a chat app, or just want to keep your comments section clean, this package can help.
 
 ## Installation
-```
+```sh
     go get -u github.com/pcpratheesh/go-censorword
 ```
+
+for previous version
+
+```sh
+    go get -u github.com/pcpratheesh/[email protected]
+```
+
 ## Usage
 ```go
 import (
 	"github.com/pcpratheesh/go-censorword"
 )
 ```
 
+
 ## In working
-go-censorword package uses a censorWord [here](censor/censor.go) list to check the profanities. 
-Als we have provided an option to override this list of contents by using
+The go-censorword package uses a censorWord [here](censor/censor.go) list to check profanities, but also provides an option for you to override this list with your own contents. You can create a list of bad words that are not included in the original blacklist by using the **customCensorList** method.
+
 ```go
-CustomCensorList() 
+CustomCensorList([]string{}) 
 ```
-You can provide your own list to search and replace the profanities
 
-## Example
+## How to use
 ```go
-var detector = gocensorword.NewDetector().SetCensorReplaceChar("*")
-detector.CustomCensorList([]string{
-    "bad", "word","one",
-})
+// this would initialize the detector object.
+var detector = gocensorword.NewDetector(
+	gocensorword.WithCensorReplaceChar("*"),
+
+    // override the existing list of bad words with your own
+    gocensorword.WithCustomCensorList([]string{
+        "bad", "word","one",
+    }),
+)
+
+// censor the word
+actualString := "with having some bad words"
+filterString, err := detector.CensorWord(actualString)
+if err != nil {
+    panic(err)
+}
+
 ```
+
+## Option Methods
+- *WithCensorReplaceChar(string)* : This method can be used to replace the filtered word characters with asterisks (*), dashes (-) or custom characters, like the pound sign (#) or at sign (@).
+- *WithCustomCensorList([]string)* : The list of your own profanity words
+- *WithSanitizeSpecialCharacters(bool)*: To sanitize the special characters in the word
+- *WithKeepPrefixChar(bool)*: If you want to Kept the prefix Character (eg : F****)
+- *WithKeepSuffixChar(bool)*: If you want to Kept the suffix Character (eg : ****K)
+
 ## Example
 ```go
-detector := NewDetector().SetCensorReplaceChar("*")
+detector := NewDetector(
+    gocensorword.WithCensorReplaceChar("*"),
+)
 
 resultString, err := detector.CensorWord(inputString)

 In the future, we should implement the following points
 - Support for other language profanities
-- All words having repeated characters more than twice (eg : fuck -> fuuuuuck)
-- Should remove word match conditions (eg :-> fucker, fucking..etc)
+- All words having repeated characters more than twice
