 ## Usage
-By default, on the first `.censor()` call, function `.load_censor_words()` generates all possible [leetspeak](https://en.wikipedia.org/wiki/Leet) words, from [profanity_wordlist.txt](./better_profanity/profanity_wordlist.txt), to be used to compare against the input texts.  The full mapping of the library can be found in [profanity.py](./better_profanity/profanity.py#L9-L18).
+It is highly recommended to call `profanity.load_censor_words()` at initialization, to reduce the runtime for the first `profanity.censor()` call.
 
-For example, the word `handjob` would be loaded into:
+```
+from better_profanity import profanity
+
+if __name__ == "__main__":
+    profanity.load_censor_words()
+    
+    text = "You p1ec3 of sHit."
+    censored_text = profanity.censor(text)
+    print(censored_text)
+    # You **** of ****.
+```
+
+All modified spellings of words in [profanity_wordlist.txt](./better_profanity/profanity_wordlist.txt) will be generated. For example, the word `handjob` would be loaded into:
 
 ```
 'handjob', 'handj*b', 'handj0b', 'handj@b', 'h@ndjob', 'h@ndj*b', 'h@ndj0b', 'h@ndj@b',
 'h*ndjob', 'h*ndj*b', 'h*ndj0b', 'h*ndj@b', 'h4ndjob', 'h4ndj*b', 'h4ndj0b', 'h4ndj@b'
 ```
 
+The full mapping of the library can be found in [profanity.py](./better_profanity/profanity.py#L9-L18).
