+about: Please follow this template when creating an issue for JuCC!
+title: ''
+labels: ''
+assignees: ''
+
+---
+
+Welcome to the issue tracker for **JuCC**! We're excited that you're interested in improving our system. Below, please **choose either a Feature Request or Bug Report** and replace the sample text below to describe the issue! Additionally, please choose the appropriate labels on the Github panel. If you wish to and are able to solve the issue, feel free to assign yourself; otherwise we will manage this later!
+
+# Feature Request
+## Summary
+Please provide a short summary of the feature you would like implemented.
+
+## Solution
+If possible, include a description of the desired solution you have in mind. Ideally, a series of steps outlining what is required and a plan to implement would be the most helpful for our developers!
+
+Feel free to suggest more or raise concerns with the existing items. When we're convinced of the list, we should make an overall project with issues for each item in the list to spread out the tasks and track progress.
+
+### Alternatives
+If you are aware of any alternatives to the solution you presented, please describe them here!
+
+___
+
+# Bug Report
+**Note**: Before filing a bug report, please make sure to check whether the bug has already been filed. If it has, please do not re-file the report, our developers are already hard at work fixing it!
+
+## Summary
+Please provide a short summary of the bug observed.
+
+## Environment
+To address the bug, especially if it environment specific, we need to know what kind of configuration you are running on. Please include the following:
+
+**OS**: Ubuntu (LTS) 20.04 or macOS 10.14+ (please specify version).
+
+**Compiler**: GCC 7.0+ or Clang 8.0+. 
+
+**CMake Profile**: `Debug`, `Release`, `FastDebug`, or `Relwithdebinfo`. If exists across all cmake profiles on a platform-compiler combo, then please say so.
+
+**CI**: If the bug has been observed in CI, please link to the CI build so that the bug can be referenced. Please make sure that if the issue has appeared on a PR branch that the PR itself is not causing the issue.
+
+## Steps to Reproduce
+Whenever possible, retrace how you came about the problem and describe so here.
+
+If you have an understanding of why the bug occurred, that would be awesome to include as well! In this case, be as descriptive as you can and provide references to lines of code in the code whenever possible!
+
+### Expected Behavior
+Fill in the behavior expected from our system, as well as the reference you used.
+
+### Actual Behavior
+Fill in the behavior you actually observed for our system.

+Welcome to the PR tracker for **JuCC**! We're excited that you're interested in improving our system.
+
+**PRs that do not follow our guidelines** will be immediately closed. In general, you should avoid creating a PR until you are reasonably confident the tests should pass, having tested locally first.
+
+Please choose the appropriate labels on the Github panel and feel free to assign yourself. Additionally, if your PR solves an open issue, please link the issue on the Github panel. Feel free to assign reviewers to your PR or we will decide who best to assign for a review.
+
+# Heading
+Please choose an appropriate heading for your PR, relevant to the changes you have made.
+
+## Description
+Please create a description of the issue your PR solves, and how you went about implementing your solution.
+
+### Remaining Tasks
+Again, you should only create PR once you are reasonably confident you are near completion. However, if there are some tasks still remaining before the PR is ready to merge, please create a checklist to track active progress.
+:pushpin: TODOs:
+- [x] ~~Stash limit in Parser for pushdown (INVALID)~~
+- [x] Add optional property support
+- [ ] Fix memory leaks
+
+## Further Work
+If your PR unlocked the potential for further improvement, please note them here and create additional issues! Do the same if you discovered bugs in the process of development.

+Here's an empty template to format yourself!
