-Have a feature you want to implement into Statping!? Awesome! Follow this guide to see how you can test, compile and build Statping for production use. I recommend you use `make` with this process, it will save you time and it will auto include many customized parameters to get everything working correctly.

 # Dependencies
-Statping has a couple of required dependencies when testing and compiling the binary. The [Makefile](https://github.com/hunterlong/statping/blob/master/Makefile) will make these tasks a lot easier. Take a look at the Makefile to see what commands are ran. Run the command below to get setup right away.

 # Compiling Assets
-This Golang project uses [rice](https://github.com/GeertJohan/go.rice) to compile static assets into a single file. The file `source/rice-box.go` is never committed to the Github repo, it is automatically created on build. Statping also requires `sass` to be installed on your local OS. To compile all the static assets run the command below:

 # Testing
-Statping includes multiple ways to Test the application, you can run the `make` command, or the normal `go test` command. To see the full experience of your updates, you can even run Cypress tests which is in the `.dev/test` folder.
 
-Statping will run all tests in `cmd` folder on MySQL, Postgres, and SQLite databases. You can run `make databases` to automatically create MySQL and Postgres with Docker.

 # Build
-Statping will build on all operating systems except Windows 32-bit. I personally use [xgo](https://github.com/karalabe/xgo) to cross-compile on multiple systems using Docker. Follow the commands below to build on your local system.

+Please remember to also add the Changelog Entry to describe what you have
+changed by using[changelog-go](https://gitlab.com/l0nax/changelog-go).
 
+If your PR is related to an Issue (ie. on a bug fix or when adding a new notifier)
+don't forget adding the related GitHub Issue ID like this: `[#270](https://github.com/hunterlong/statping/issues/270)`
+Check out the example below.
+Adding _one_ changelog entry should be done in a separate Commit - not only
+because this is a good Committing practice, also because it's separated by your
+Changes.
+When you fix/ add/ ... more than one thing than please describe it a good, short
+and precise sentence. Because everyone wants a good and nice-looking `CHANGELOG.md`
+where all changes of a new Version are documented.
