+- [Steps for your contribution](#steps-for-your-contribution)
+
+## Simple steps for your feedback
+
+1. As eSpeak NG is open source software, you can get it working from many different sources, some of which may provide quite
+old version. Before registering new issue, test that issue can be reproduced with latest development version at
+[eSpeak NG online](https://odo.lv/Espeak) site.
+
+2. Review known [eSpeak NG issues](https://github.com/espeak-ng/espeak-ng/issues), particularly about
+[languages](https://github.com/espeak-ng/espeak-ng/labels/languages%2Fpronunciation) and add your comments
+on existing issues. If necessary add new issue as described [here](https://help.github.com/en/articles/creating-an-issue).
+
+3. Look at and subscribe to [eSpeakNG mailing list](https://groups.io/g/espeak-ng)
+to view and discuss other related topics.
+
+## Steps for your contribution
+1. Get familiar with [additive speech synthesis](https://en.wikipedia.org/wiki/Additive_synthesis).
+
+2. Create fork of [espeak-ng](https://github.com/espeak-ng/espeak-ng) repository as it is described [here](https://help.github.com/en/articles/fork-a-repo).
+
+3. [Clone](https://help.github.com/en/articles/cloning-a-repository) and set up your development environment [on your computer](building.md) , or clone it [online](https://odo.lv/EspeakGuide).
+
+4. Get familiar with [text to phoneme translation](dictionary.md) and how to [add or improve language](add_language.md).
+
+5. Get familiar with [voice files](voices.md) and [phoneme tables](phontab.md) configuration files.
+
+6. Make your improvements (i.e. additions or modifications) and check your project with `make check` command. Fix issues if necessary.
+
+7. If you contribute to an existing language, find language maintainer in language configuration file located in `espeak-ng-data/lang` folder[1](#1) and ask him to review your changes. If you can't find language maintainer, you can review list of all contributors[2](#2) and contact them. You can also volunteer to become language maintainer just by updating language configuration file.
+
+8. [Push your changes to GitHub](https://help.github.com/en/articles/pushing-commits-to-a-remote-repository) and create [pull request](https://help.github.com/en/articles/creating-a-pull-request). You can also send changed files by email to [eSpeakNG mailing list](https://groups.io/g/espeak-ng) (but then inlusion of them may take more time).
+
+9. Wait for feedback of current espeak-ng maintainers[3](#3).
+
+10. If you feel ready to take responsibility, ask existing maintainers to become promoted as a maintainer of the project.
+
+----
+
+1. You can get list of all language maintainers with following commands in your `espeak-ng` folder:
+
+```
+cd espeak-ng-data;grep -ri -A2 -B2 maintainer *
+```
+
+2. You can get list of all contributors with following commands in your `espeak-ng` folder:
+
+```
+git log --pretty="%an %ae%n%cn %ce" | sort|uniq -c|sort -nr
+```
+3. Currently eSpeak NG is maintained only by volunteers in their free time, therefore expected reaction time is one, two weeks.
