DX improvements

[mostafa]

I think these need to be changed or added:

• [ ] Add contributing guide and mention the best practices like the changes in #89 and many others
• [ ] Add issue and PR template
• [ ] Add security issue reporting guide
• [ ] Add CLA? (not sure if it is necessary)
• [x] #152
  • Manually added to the release files.
• [x] #155
• [x] #78
• [ ] #43
• [ ] Add better docs:
  • Partially addressed in #89 by updating README and the JS API docs.
• [ ] Automatically create the release description
