+# Hooks
+
+This plugin uses the following hooks (defined since Chamilo LMS 1.10.0):
+
+* HookAdminBlock
+* HookWSRegistration
+* HookNotificationContent
+* HookNotificationTitle
+
+
+# Web services
+
+This plugin also enables new webservices that can be used from registration.soap.php
+
+* HookAdvancedSubscription..WSSessionListInCategory
+* HookAdvancedSubscription..WSSessionGetDetailsByUser
+* HookAdvancedSubscription..WSListSessionsDetailsByCategory
+
+See `/plugin/advanced_subscription/src/HookAdvancedSubscription.php` to check Web services inputs and outputs
+
+# How does this plugin works?
+
+After install, fill the required parameters (described above)
+Use web services to communicate course session inscription from external website
+This allows students to search course sessions and subscribe if they match
+the requirements.
+
+The normal process is:
+* Student searches course session
+* Student reads session info depending student data
+* Student requests to be subscribed
+* A confirmation email is sent to student
+* An authorization email is sent to student's superior (STUDENT BOSS role) or admins (when there is no superior) who will accept or reject the student request
+* When the superior accepts or rejects, an email will be sent to the student and superior (or admin), respectively
+* To complete the subscription, the request must be validated and accepted by an admin

+AI Helper plugin
+======
+
+Version 1.1
+
+> This plugin is meant to be later integrated into Chamilo (in a major version
+release).
+
+The AI helper plugin integrates into parts of the platform that seem the most useful to teachers/trainers or learners. 
+Because available Artificial Intelligence (to use the broad term) now allows us to ask for meaningful texts to be generated, we can use those systems to pre-generate content, then let the teacher/trainer review the content before publication.
+
+Currently, this plugin is only integrated into:
+
+ - exercises: in the Aiken import form, scrolling down
+ - learnpaths: option to create one with openai
+
+### OpenAI/ChatGPT
+
+The plugin, created in early 2023, currently only supports OpenAI's ChatGPT API.
+Create an account at https://platform.openai.com/signup (if you already have an API account, go 
+to https://platform.openai.com/login), then generate a secret key at https://platform.openai.com/account/api-keys 
+or click on "Personal" -> "View API keys".
+Click the "Create new secret key" button, copy the key and use it to fill the "API key" field on the 
+plugin configuration page.
+
+# Changelog
+
+## v1.1
+
+Added tracking for requests and differential settings to enable only in exercises, only in learning paths, or both.
+
+To update from v1.0, execute the following queries manually.
+```sql
+CREATE TABLE plugin_ai_helper_requests (
+id int(11) NOT NULL AUTO_INCREMENT,
+user_id int(11) NOT NULL,
+tool_name varchar(255) COLLATE utf8_unicode_ci NOT NULL,
+requested_at datetime DEFAULT NULL,
+request_text varchar(255) COLLATE utf8_unicode_ci NOT NULL,
+prompt_tokens int(11) NOT NULL,
+completion_tokens int(11) NOT NULL,
+total_tokens int(11) NOT NULL,
+PRIMARY KEY (id)
+) DEFAULT CHARACTER SET utf8 COLLATE `utf8_unicode_ci` ENGINE = InnoDB;
+```
+If you got this update through Git, you will also need to run `composer install` to update the autoload mechanism.

+# Azure Active Directory Changelog
+
+## 2.4 - 2024-08-28
+
+* Added a new user extra field to save the unique Azure ID (internal UID).
+This requires manually doing the following changes to your database if you are upgrading from v2.3
+```sql
+INSERT INTO extra_field (extra_field_type, field_type, variable, display_text, default_value, field_order, visible_to_self, visible_to_others, changeable, filter, created_at) VALUES (1, 1, 'azure_uid', 'Azure UID (internal ID)', '', 1, null, null, null, null, '2024-08-28 00:00:00');
+```
+* Added a new option to set the order to verify the existing user in Chamilo
+```sql
+INSERT INTO settings_current (variable, subkey, type, category, selected_value, title, comment, scope, subkeytext, access_url, access_url_changeable, access_url_locked) VALUES ('azure_active_directory_existing_user_verification_order', 'azure_active_directory', 'setting', 'Plugins', '', 'azure_active_directory', '', '', '', 1, 1, 0);
+```
+* Added a new option to update user info during the login proccess.
+```sql
+INSERT INTO settings_current (variable, subkey, type, category, selected_value, title, comment, scope, subkeytext, access_url, access_url_changeable, access_url_locked) VALUES ('azure_active_directory_update_users', 'azure_active_directory', 'setting', 'Plugins', '', 'azure_active_directory', '', '', '', 1, 1, 0);
+```
+* Added new scripts to syncronize users and groups with users and usergroups (classes). And an option to deactivate accounts in Chamilo that do not exist in Azure.
+```sql
+INSERT INTO settings_current (variable, subkey, type, category, selected_value, title, comment, scope, subkeytext, access_url, access_url_changeable, access_url_locked) VALUES ('azure_active_directory_tenant_id', 'azure_active_directory', 'setting', 'Plugins', '', 'azure_active_directory', '', '', '', 1, 1, 0);

+```
+
+## 2.3 - 2021-03-30
+
+* Added admin, session admin and teacher groups. This requires adding the following fields to your database if 
+  upgrading from a previous version of the plugin manually:
+```
+INSERT INTO settings_current (variable, subkey, type, category, selected_value, title, comment, scope, subkeytext, access_url, access_url_changeable, access_url_locked) VALUES ('azure_active_directory_group_id_admin', 'azure_active_directory', 'setting', 'Plugins', '', 'azure_active_directory', '', null, null, 1, 1, 0);

+# The Azure Active Directory Plugin
+
+This plugin allows users to authenticate (with OAuth2) through Microsoft's Azure Active Directory.
+This will modify the login form to either substitute the default login form or add another option to connect through
+Azure.
+An option allows you to automatically provision/create users in Chamilo from their account on Azure if they don't exist
+in Chamilo yet.
+
+This plugin adds two extra fields for users:
+
+* `organisationemail`, the email registered in Azure Active Directory for each user (under _Email_ in the _Contact info_ section).
+* `azure_id`, to save the internal ID for each user in Azure (which is also the prefix before the _@_ sign in the _User Principal Name_).
+
+### Prerequisites
+This plugin will *not* work if you do not use HTTPS. 
+Make sure your portal is in HTTPS before you configure this plugin.
+
+### To configure Azure Active Directory
+* Create and configure an application in your Azure panel (Azure Active Directory -> Applications registration -> New registration)).
+* In the _Authentication_ section, set an _Reply URL_ (or _Redirect URIs_) of `https://{CHAMILO_URL}/plugin/azure_active_directory/src/callback.php`.
+* In the _Front-channel logout URL_, use `https://{CHAMILO_URL}/index.php?logout=logout`.
+* Leave the rest of the _Authentication_ section unchanged.
+* In _Certificates & secrets_, create a secret string (or application password). Keep the _Value_ field at hand. If you don't copy it somewhere at this point, it will later be hidden, so take a copy, seriously!
+* Make sure you actually have users.
+
+### To configure this plugin
+* _Enable_: You can enable the plugin once everything is configured correctly. Disabling it will return to the normal Chamilo login procedure.
+* _Application ID_: Enter the _Application (client) ID_ assigned to your app when you created it in your Azure Active Directory interface, under _App registrations_.
+* _Application secret_: Enter the client secret _value_ created in _Certificate & secrets_ above.
+* _Block name_: (Optional) The name to show above the login button.
+* _Force logout button_: (Optional) Add a button to force logout from Azure.
+* _Management login_: (Optional) Disable the chamilo login and enable an alternative login page for users.   
+   You will need copy the `/plugin/azure_active_directory/layout/login_form.tpl` file to `/main/template/overrides/layout/` directory.
+* _Name for the management login_: A name for the manager login. By default, it is set to "Management Login".
+* _Automated provisioning_: Enable if you want users to be created automatically in Chamilo (as students) when they don't exist yet.
+* Assign a region in which the login option will appear. Preferably `login_bottom`.
+
+### Enable through the normal login form
+You can configure the external login procedure to work with the classic Chamilo form login.
+To do it, make sure users have _azure_ in their auth_source field, then add this line in `configuration.php` file
+```php
+$extAuthSource["azure"]["login"] = $_configuration['root_sys']."main/auth/external_login/login.azure.php";
+```
+
+### Dependencies
+> This plugin uses the [`thenetworg/oauth2-azure`](https://github.com/TheNetworg/oauth2-azure) package.
