I left a few suggestions for improvement. Thanks for preparing that!

@baranwalayush Basically, LGTM.
But maybe, this file is a little bit huge size.
CONTRINUTING.md is an entry point for new contributors, so this file should be shortened as much as possible.
This repo, official golang github repo is a great example for you.

LGTM

@tyzerrr Thank you for the suggestion! In the case of Golang, they have a separate webpage for contribution guidelines where they are redirecting from the contributing.md page, which is not true in our case. Besides that, I believe that there is nothing overwhelming in this file and a new contributor can easily read and understand the guidelines.

Thanks for this contribution!

Hi @draeger, I have updated this PR to include the steps for running SBML Test Runner, as discussed in #107.

[Copilot]

Pull request overview

Adds a new CONTRIBUTING.md to onboard contributors, expands the SBML Test Runner setup section in INSTALL.md, switches the README "For developers" section to "For Contributors" with a link to the new file, and makes two small code adjustments: switching the default test-runner wrapper script back to the non-LSODA wrapper class, and replacing the JUnit fail(...) call in SEDMLExample with a RuntimeException (also fixing the "Simulatation" typo).

Changes:

• New CONTRIBUTING.md covering bug reports, enhancement requests, code contribution workflow, and links to INSTALL.md for setup.
• Rewrites the SBML Test Runner section of INSTALL.md into numbered steps and updates README.md to point to CONTRIBUTING.md and list it in the project structure.
• Updates sbml_test_suite_runner_wrapper.sh to invoke SBMLTestSuiteRunnerWrapper (non-LSODA) and replaces the JUnit fail(...) in SEDMLExample.java with a RuntimeException to remove the test-scope dependency from a main-source example.
