 # Telethon
-**Telethon** is Telegram client implementation in Python. This project's _core_ is **completely based** on [TLSharp](https://github.com/sochix/TLSharp), so please, also have a look to the original project!
+**Telethon** is Telegram client implementation in Python. This project's _core_ is **completely based** on
+[TLSharp](https://github.com/sochix/TLSharp). All the files which are fully based on it will have a notice
+on the top of the file. Also don't forget to have a look to the original project.
 
-Other parts, such as the request themselves, the .tl tokenizer and code generator, or some ported C# utilities such as `BinaryWriter`, `BinaryReader`, `TCPClient` and so on, are no longer part of TLSharp itself.
+The files without the previously mentioned notice are no longer part of TLSharp itself, or have enough modifications
+to make them entirely different.
 
 ### Requirements
-This project requires the following Python modules, which can be installed by issuing `sudo -H pip install <module>` on a Linux terminal:

 ### We need your help!
-As of now, the project is fully **untested** and with many pending things to do. If you know both Python and C#, please don't think it twice and help us (me)!

 ### Code generator limitations
 The current code generator is not complete, yet adding the missing features would only over-complicate an already hard-to-read code.
-Some parts of the .tl file _should_ be omitted, because they're "built-in" in the generated code (such as writing booleans, etc.).
