+## Usage Guide

+This is a simple browser extension that takes a json containing information on a schedule and shows it using HTML Tables. Because it is a browser extension, you can check your schedule anytime, anywhere while browsing the web.
-- Some pages within the extension popup.
+### Load Schedule
-
+The schedule can be loaded in many different ways, using the the first page of the extension. Some of the ways are as follows:
+
+- **PACO API:** This extension uses an unofficial API that fetches data directly from [https://paco.ua.pt/secvirtual](https://paco.ua.pt/secvirtual). One of the endpoints is the student's schedule. For this to work, the institutional email and password need to be provided, hence the "login" page at the beginning [[3]](#3---different-ways-to-load-the-schedule). This will fetch the schedule configuration into the extension.
+
+- **Upload directly from PACO:** While using the extension, two buttons are added to the schedule interface [[2]](#2---possibility-to-either-download-the-schedule-configuration-or-upload-it-directily-to-the-extension) at [https://paco.ua.pt/secvirtual/horarios/c_horario_aluno.asp](https://paco.ua.pt/secvirtual/horarios/c_horario_aluno.asp). If you click the Upload ⭱ button, the schedule configuration will be added to the extension.
+
+- **Drag and drop configuration file:** If you have a configuration JSON file of the schedule, you can simply drag and drop it in the "login" page at the beginning [[3]](#3---different-ways-to-load-the-schedule). A configuration file can be obtained either within the extension, on an already setup schedule, through the Download ⭳ button in the side bar [[1]](#1---some-pages-within-the-extension-popup), or through the same button within the schedule interface in [https://paco.ua.pt/secvirtual](https://paco.ua.pt/secvirtual/horarios/c_horario_aluno.asp) [[2]](#2---possibility-to-either-download-the-schedule-configuration-or-upload-it-directily-to-the-extension).
+
+- **Through the Browser Console:** A less convenient way would be to use the Browser Console and, using JavaScript, update the storage manually. To achieve this, do the following:
+ - Right click anywhere **within** the Extension and select **Inspect**
+ - When the **DevTools** window opens, click **Console** in the top navbar
+ - Write the code of [[example code]](#example-code)
+ - Press Enter. If the ouput is something like ```Promise {}```, then it worked
+
+#### Example code
+```javascript
+// pass the JSON schedule configuration to the function set()
+chrome.storage.sync.set({
+ "schedule": {
+ "Segunda": [
+ {
+ ...
+ },
+ {
+ ...
+ },
+ ...
+ ],
+ "Terça": [
+ {
+ ...
+ },
+ ...
+ ],
+ ...
+ },
+ "school_year": "2021/2022",
+ "semester": 1
+})
+```
+To know more about the format of the Schedule Configuration JSON, go to [https://github.com/digas99/paco-ua-api/blob/main/docs/README.md#hor%C3%A1rio](https://github.com/digas99/paco-ua-api/blob/main/docs/README.md#hor%C3%A1rio).
+
+### Schedule Page
+
+When a schedule is successfully loaded into the extension, it is displayed in a different page, on a table [[1]](#1---some-pages-within-the-extension-popup). Here, you can choose between a view of the entire **Week**, or simply the classes for **Today**, the day before (**Yesterday**) and the day after (**Tomorrow**). The view you choose will show up the next time you open the extension.
-- Possibility to either download the schedule configuration, or upload it directily to the extension.
+Clicking on the days of the week in the Week view will also show the classes for that one day specifically.
-
+Every view of a single day will show a lateral info container with details on the classes for that day.
+
+The lateral navbar has three buttons with actions on the schedule:
+- **Expand/Trim:** adapt the number of hours shown in the schedule, where trimming removes the hours not used for classes (holes in the schedule won't be removed)
+- **Download Schedule Configuration:** download JSON file with the configuration of the schedule
+- **Print Schedule:** take a picture of the schedule and download it
+
+### Settings
+
+There is a page that provides ways of customizing your experience with the app. The settings are the following:
+- **Schedule**
+ - **Schedule on Startup:** choose which type of schedule should show when opening the extension.
+ - **Subject Colors:** customize the colors of each subject.
+ - **Highlight Cell of Now:** Highlight the cell in the schedule that corresponds to the current time.
+ - **Limit Schedule Trim:** limit min and max hours of the trim. This values are taken from the schedule itself.
+- **Account**
+ - **Remember Email:** remember email the next time you logout.
+- **PACO**
+ - **Download and Upload buttons:** extra buttons above the schedule in the schedule page in PACO - Secretaria Virtual.
