-# Moodle assigment upload
+# KTU Moodle assignment upload
+
+This will automatically open up moodle and upload/update any assignment file.
+
+It works by using selenium to access the moodle website by emulating what a
+normal person would do.
+
+## Why?
+So I could use this together with ["KTU OOP Report Generator"](https://github.com/RokasPuzonas/ktu-oop-report-generator)
+and [Github Actions](https://github.com/features/actions) to automatically generate
+a report and upload it to moodle whenever I push a commit or tag.
+
+And also because I love automating everyday tasks.
+
+## Usage
+
+1. Clone repository
+```shell
+git clone https://github.com/RokasPuzonas/ktu-moodle-assignment-upload
+```
+
+2. Setup [virtualenv](https://pythonbasics.org/virtualenv)
+```shell
+python -m venv venv
+```
+
+4. Active enviroment
+```shell
+source venv/bin/activate
+```
+
+4. Install dependencies
+```shell
+pip install -r requirements.txt
+```
+
+5. Determine your assignment
+For this script to work, it needs to know to what assignment you want to upload
+the file. Luckily this is super simple to do, just open up the webpage where
+the you can view the assignment and take a look at the url.
+

+
+6. That's it, you're done!
+Now you can run the script!
+
+```shell
+./main.py <assignment-id> <filename> <upload-filename> --username <username> --password <password>
+```
+
+## Example
+
+```shell
+./main.py 1610 report.pdf IF-1-1_Bob_Bobby.pdf --username bob --password ilovecats
+```
