+# Burndown Chart for GitHub Projects
+An easy to use [burndown chart](https://www.scrum.org/resources/scrum-glossary#:~:text=B-,burn-down%20chart,-%3A%C2%A0a%20chart%20which) generator for [GitHub Project Boards](https://docs.github.com/en/issues/organizing-your-work-with-project-boards/managing-project-boards/about-project-boards).

+* [Usage](#usage)
+* [Contributing](#contributing)
+* [About](#about)
+
+## Features
+* Create a **burndown chart for a GitHub Project Board**.
+* Works for **private repositories**.
+* Includes a **trend line** for the current sprint.
+* Supports custom labels for **tracking points for issues**
+
+## Assumptions
+This tool, while flexible, makes the following assumptions about your project management workflow:
+* You use one and only one [GitHub Project Board](https://docs.github.com/en/issues/organizing-your-work-with-project-boards/managing-project-boards/about-project-boards) for each of your [Sprints](https://scrumguides.org/scrum-guide.html#the-sprint)
+* You use one and only one [GitHub Milestone](https://docs.github.com/en/issues/using-labels-and-milestones-to-track-work/about-milestones) for each of your [User Stories](https://www.scrum.org/resources/blog/user-story-or-stakeholder-story)
+* You use one and only one [GitHub Issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/about-issues) for each of your [Sprint Backlog Items/Tasks](https://scrumguides.org/scrum-guide.html#sprint-backlog)
+* Each of your GitHub Issues has a [label](https://docs.github.com/en/issues/using-labels-and-milestones-to-track-work/managing-labels) indicating how many [points](https://www.scrum.org/resources/scrum-glossary#:~:text=several%20ways%20such%20as-,user%20story%20points,-or%20task%20hours.%20Work) its corresponding task is worth.
+    - Furthermore, all labels that indicate point values have the format `<prefix><int>`.
+    - However, multiple labels indicating points on the same Issue are supported.
+* A Sprint Backlog Task is considered [Done](https://www.scrum.org/resources/professional-scrum-developer-glossary#:~:text=D-,definition%20of%20done%3A,-a%20shared%20understanding) if its corresponding GitHub Issue is Closed.
+
+## Installation
+### 0. Clone this repository
+```
+git clone https://github.com/jhale1805/github-projects-burndown-chart.git
+cd github-projects-burndown-chart
+```
+### 1. Create a virtual environment
+```
+python -m venv ./venv
+```
+
+### 2. Activate the virtual environment
+
+*Linux/Mac OS*
+```
+source venv/bin/activate
+```
+*Windows (Powershell)*
+```
+.\venv\Scripts\activate
+```
+*Windows (Command Prompt)*
+```
+.\venv\Scripts\activate.bat
+```
+
+### 3. Install the dependencies
+```
+pip install -r requirements.txt
+```
+
+## Usage
+1. Create a [Personal Access Token](https://github.com/settings/tokens) with the `repo` scope.
+    - Do not share this token with anyone! It gives the bearer full control over all private repositories you have access to!
+    - This is required to pull the Project Board data from GitHub's GraphQL API.
+2. Make a copy of `src/config/secrets.json.dist` without the `.dist` ending.
+    - This allows the `.gitignore` to exclude your `secrets.json` from being accidentally committed.
+3. Fill out the `github_token` with your newly created Personal Access Token.
+4. Make a copy of `src/config/config.json.dist` without the `.dist` ending.
+    - This allows the `.gitignore` to exclude your `config.json` from being accidentally committed.
+5. Fill out all the configuration settings
+    - `repo_owner`: The username of the owner of the repo.
+        - For example, `jhale1805`
+    - `repo_name`: The name of the repo.
+        - For example, `github-projects-burndown-chart`
+    - `project_number`: The id of the project for which you want to generate a burndown chart. This is found in the URL when looking at the project board on GitHub.
+        - For example, `1` from [`https://github.com/jhale1805/github-projects-burndown-chart/projects/1`](https://github.com/jhale1805/github-projects-burndown-chart/projects/1)
+    - `sprint_start_date`: The first day of the sprint. Formatted as `YYYY-MM-DD`. 
+        - Must be entered here since GitHub Project Boards don't have an assigned start/end date.
+        - For example, `2021-10-08`
+    - `sprint_end_date`: The last day of the sprint. Formatted as `YYYY-MM-DD`.
+        - Must be entered here since GitHub Project Boards don't have an assigned start/end date.
+        - For example, `2021-10-22`
+    - `points_label`: The prefix for issue labels containing the point value of the issue. Removing this prefix must leave just an integer.
+        - For example: `Points: ` (with the space)
+6. Run `python src/main.py` to generate the burndown chart.
+    - This will pop up an interactive window containing the burndown chart, including a button for saving it as a picture.
