The guide below provides the flow for creating a perfect pull request to the Telegram X Repository. Before submitting your PR, ensure that it complies with the following principles.

Perfect PRs must be:

• Rational. Explain the changes you've made. Be explicit and describe the changes in a few short, concise sentences.
• Completed. All changes are properly tested and ready to be merged.
• Up-To-Date. Your PR is based on the latest commit of the 'main' branch.

When fixing issues, make sure that your PR is:

• Sufficient. Changes must fix the cause of an issue, not its effects.
• Separated. Different bug fixes are divided into independent PRs.
• Linked. If you fix a specific issue, add it to the title and its description to the body.
• Creating. The fix does not break anything in other interfaces or on specific devices.
• Consistent. Use the proper design relevant to the issue. If the design is missing, the PR must include at least two screenshots (before and after the changes).

When adding features, expect:

• Discussion. If you implement a feature that requires a new design for the app, be ready to receive and follow comments or edit suggestions.
• Dismissal. If the feature design you submitted is below our expectations, if it cripples the UX, or the feature-to-user impact is minor, your PR will be declined. All the features must strictly follow the Telegram X flow – matching the overall quality, stability, and the general style of the app.

Other contributions:

PR types not mentioned above can be considered as well, provided they are rational. For example, optimizations of existing features or the app build time (for this, before/after timing is mandatory). For code refactoring, the code should be clearly improved/simplified/more convenient and is expected to be free of any edge-case bugs.

Good luck and thanks for the contribution!
