+# Contribution Guideline
+
+First of all: I am thankful for any contribution this project gets.
+
+## Creating Issues
+
+You found a bug, you miss some feature in the project or have an idea how to
+improve the code? Then [create a GitHub issue](https://github.com/progsource/maddy/issues/new).
+
+## Creating Pull-Requests
+
+* Use a branch other than master.
+* Add yourself to the `AUTHORS` file.
+* Try to stick with the code style the files are having right now.
+* Write in your commit messages what/why you did something. Often times a one-liner might be enough, but if you want to write more, make an empty line in between like:
+  ```
+  Short description
+
+  More and longer text for the commit message with some more information.
+  That can go over multiple lines.
+  ```
+  Do not include Github issue ticket numbers inside commit messages.
+* Explain for what your PR is for - like providing a use-case or something similar.
+* Update documentation of the Markdown syntax if anything changed there. (`docs/definitions.md`)
+* Add a changelog entry at "Upcoming" inside of `CHANGELOG.md`
+* Make sure, that the tests are successful.

 fitting my needs. So I simply wrote my own one.
 
 ## Markdown syntax
 
 The supported syntax can be found in the [definitions docs](docs/definitions.md).
 
+## How to add maddy to your cmake project
+
+You can use [FetchContent](https://cmake.org/cmake/help/latest/module/FetchContent.html)
+which was introduced in CMake 3.11.
+
+This way you can add
+
+```cmake
+include(FetchContent)
+
+FetchContent_Declare(
+  maddy
+  URL https://github.com/progsource/maddy/.../maddy-src.zip
+)
+FetchContent_MakeAvailable(maddy)

+add_executable(my_exe)
+target_link_libraries(my_exe PUBLIC maddy)
+```
+
+to your CMake file to make it work. Check the
+[release](https://github.com/progsource/maddy/releases) for the full
+zip-file-url.
+
+The zip only contains a `CMakeLists.txt`, the `include` folder and the `LICENSE`
+file.

+## LaTeX(MathJax) block support
+
+To turn on the LaTeX support - which basically is only a
+[MathJax](https://www.mathjax.org/) support and makes sure, that formulas aren't
+internally checked for other parsers - it has to be enabled in config:
+
+```cpp
+std::shared_ptr<maddy::ParserConfig> config = std::make_shared<maddy::ParserConfig>();
+config->enabledParsers |= maddy::types::LATEX_BLOCK_PARSER;
+
+std::shared_ptr<maddy::Parser> parser = std::make_shared<maddy::Parser>(config);
+std::string htmlOutput = parser->Parse(markdownInput);
+```
+
+After this you can do the following in Markdown:

+```
+$$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$
+```
+
+Which results in
