+# commit-calendar
+
+Display a list of dates and commits from public GitHub repositories.
+You will display the list in the terminal, and you can choose to save it to a CSV file (";" separated) and display into a browser (thanks to [itty.bitty](https://itty.bitty.site))
+
+Commit Calendar is a CLI utility based on [Minicli](https://github.com/minicli/minicli).
+
+## Installation
+
+Requirements:
+- `php-cli` >= 7.3
+- Composer
+
+Installation:
+
+1. Clone this repository
+2. Run `composer install`
+
+## How to use
+
+In a terminal, in the project folder:
+
+```bash
+./commit-calendar display owner=OWNER name=NAME [number=NUMBER]
+```
+
+- OWNER: is the repository owner
+- NAME: is the repository name
+- NUMBER: the number of commits you want to extract
+
+For example: from this url https://github.com/dottxado/pico-macro-pad the OWNER is "dottxado" and the name is "pico-macro-pad", resulting in
+```bash
+./commit-calendar display owner=dottxado name=pico-macro-pad
+```
+
+While OWNER and NAME are required, and if not given they will be queried by the CLI, NUMBER has a default value of 30.
+
+## Help
+In a terminal, in the project folder:
+
+```bash
+./commit-calendar help
+```
+will display the available commands, and
+
+```bash
+./commit-calendar help display
+```
+will display the help for the display command.
