+## Issues & Pull Requests
+
+### Creating an Issue
+
+Before **creating** an Issue i.e for `features`/`bugs`/`improvements` please follow these steps:
+
+
+1. Search existing Issues before creating a new Issue (look to see if the Issue has already been created).
+1. If it doesn't exist create a new Issue giving as much context as possible (please take note and select the correct Issue type, for example `bug`, `documentation` or `feature`.
+1. If you wish to work on the Issue once it has been triaged, please include this in your Issue description.
+
+### Working on an Issue
+
+Before working on an existing Issue please follow these steps:
+
+1. Comment asking for the Issue to be assigned to you.
+1. To best position yourself for Issues assignment, we recommend that you:
+    1. Confirm that you have read the CONTRIBUTING.md.
+    1. Have a functional development environment (have built and are able to run the project).
+    1. Convey your intended approach to solving the issue.
+    1. Put each of these items in writing in one or more comments.
+1. After the Issue is assigned to you, you can start working on it.
+1. In general, **only** start working on this Issue (and open a Pull Request) when it has been assigned to you. Doing so will prevent confusion, duplicate work (some of which may go unaccepted given its duplicity), incidental stepping on toes, and the headache involved for maintainers and contributors alike as Issue assignments collide and heads bump together. 
+1. Reference the Issue in your Pull Request (for example `This PR fixes #123`). so that the corresponding Issue is automatically closed upon merge of your Pull Request.
+
+> Notes:
+>
+> - Check the `Assignees` box at the top of the page to see if the Issue has been assigned to someone else before requesting this be assigned to you. If the issue has a current Assignee, but appears to be inactive, politely inquire with the current Assignee as to whether they are still working on a solution and/or if you might collaborate with them.
+> - Only request to be assigned an Issue if you know how to work on it.
+> - If an Issue is unclear, ask questions to get more clarity before asking to have the Issue assigned to you; avoid asking "what do I do next? how do I fix this?" (see the item above this line)
+> - An Issue can be assigned to multiple people, if you all agree to collaborate on the Issue (the Pull Request can contain commits from different collaborators)
+> - Any Issues that has no activity after 2 weeks will be unassigned and re-assigned to someone else.
+
+## Reviewing Pull Requests
