 Telegram Desktop is not a standalone application but a part of [Telegram project][telegram], so all the decisions about the features, languages, user experience, user interface and the design are made inside Telegram team, often according to some roadmap which is not public.
 
-## Sign your work
-
-For contributions to be accepted they should be granted into the public domain. This will solve the issue if Telegram team needs to use full Telegram Desktop source code with some different license.
-
-The sign-off is a simple line at the end of the explanation for the patch. Your signature certifies that you wrote the patch and you have the right to put it in the public domain. The rules are pretty simple: if you can certify the below:
-
-```
-Telegram Desktop Developer Certificate of Origin
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole by me or is based upon
-    previous work that, to the best of my knowledge, is in the
-    public domain and I have the right to put it in the public domain.
-
-(d) I understand and agree that this project and the contribution are
-    public and that a record of the contribution (including all
-    metadata and personal information I submit with it, including my
-    sign-off) is maintained indefinitely and may be redistributed.
-
-(e) I am granting this work into the public domain.
-```
-
-Then you just add a line to every **git commit message** that states:
-
-    Signed-off-by: Random J Developer <random@developer.example.org> (github: rndjdev_github)
-
-Replacing Random Developer’s details with your name, email address and GitHub username.
-
-### Change commit message of a pushed commit
-
-If you already pushed a commit and forgot to add the signature to the commit message, follow these steps to change the message of the commit:
-
-1. Open `Git Bash` (or `Git Shell`)
-2. Enter following command to change the commit message of the most recent commit: `git commit --amend`
-3. Press <kbd>i</kbd> to get into Insert-mode
-4. Change the commit message (and add the [signature](#sign-your-work) at the and)
-5. After editing the message, press <kbd>ESC</kbd> to get out of the Insert-mode
-6. Write `:wq` and press <kbd>Enter</kbd> to save the new message or write `:q!` to discard your changes
-7. Enter `git push --force` to push the commit with the new commit message to the remote repository
