+# How to contribute
+
+I'm really glad you're reading this, if you are willing to contribute to this project in some form.
+This is a quite small project with relatively low complexity so conventions are not as strict as they might be elsewhere. I am keen to learn whether and how this thing was useful to you, where you had problems and what you think could be improved.
+
+Here are some important resources:
+
+  * This [Blogpost](https://www.commander1024.de/wordpress/2020/03/fotos-mit-daten-zu-radioaktiver-strahlung-taggen) tells you about intention and scope for this tool (in German).
+  * For questions and suggestions, you can [E-Mail](mailto:commander@commander1024.de) me directly.
+  * Bugs? [Gitlab](https://git.commander1024.de/Commander1024/radiation-tager/issues) is where to report them.
+
+## Submitting changes
+
+Please send a [Pull Request to radiation_tagger](https://git.commander1024.de/Commander1024/radiation-tager/pulls) in the develop branch with a clear list of what you've done (read more about [pull requests](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request)). Please follow our coding conventions (below) and make sure all of your commits are atomic (one feature per commit).
+Keep in mind that I am a bloody beginner and probably make more mistakes than you, so I am always open for improvements.
+
+Always write a clear log message for your commits. One-line messages are fine for small changes, but bigger changes should look like this:
+
+    $ git commit -m "A brief summary of the commit
+    > 
+    > A paragraph describing what changed and its impact."
+
+## Coding conventions
+
+Start reading the code and you'll get the hang of it. We optimize for readability:
+
+  * We indent using 4 spaces (soft tabs).
+  * We use "describing" variables with underscores like 'position_list'.
+  * Classes and functions go to functions.py to keep the main program small and easy to understand.
+  * We generally follow the Python 3 coding style guidelines.
+  * This is open source software. Consider the people who will read your code, and make it look nice for them. It's sort of like driving a car: Perhaps you love doing donuts when you're alone, but with passengers the goal is to make the ride as smooth as possible.
+
+Thanks,
+Commander1024

+### Setting up a virtual environment using pipenv
+
+If you prefer to use more updated versions of the dependencies or you do not want to use Python dependencies into your system, I prepared a pipenv virtual environment for you.
+
+Using `pipenv install` all dependencies will be installed automatically. With `pipenv shell` you can source the venv.
+
+For py3exivv2 to work / compile the following dependencies must be installed - preferably from your system's package manager:
+
+  * [exiv2](http://www.exiv2.org/) and it's development package. Exiv2 is a Cross-platform C++ library and a command line utility to manage image metadata.
+  * [boost](https://www.boost.org/) and it's development package. Boost provides free peer-reviewed portable C++ source libraries.
