+iAssign version 2.1.70
+------------------------
+
+By iMatica/iMath - free interactive tools for teaching-learning Math
+   Patricia Rodrigues <patricnet@ig.com.br>, Leônidas O. Brandão <leo@ime.usp.br>
+
+
+.: About iAssign :.
+
+This is the iAssign (Interactive Assignment) package, an iMath free system to enrich activities in Moodle. 
+It is created by Patricia Rodrigues and Leônidas de Oliveira Brandão.
+
+iAssign's goal is to increase interactivity in activities related to specific subjects (such as Geometry, Functions, Programming,...)
+in a flexible way. 
+
+In order to improve interactivity, iAssign makes use of iLM (interactive Learning Module),
+that is any interactive tool that runs under a Web browser.
+Typically an iLM is a Java applet or an HTML5 package with a few (mandatory) communication methods, all based on HTTP protocol.
+This implies that any applet can easily became an iLM and can be integrated to Moodle under iAssign package. 
+
+If the iLM offers automatic assessment functionality, iAssign is able
+to deal with it. Under such iLM, iAssign provides immediate feedback to
+the student, and the teachers can get instant information about their
+activities (including reports about the student performance).
+
+It can be added new iLM into iAssign, at any time, but (for security
+reason), only the administrator has the privilege of integrating new iLM into iAssign.
+Once integrated, an iLM can be used by anyone registered in its Moodle.
+For instance, an user with privileges of "teacher" is allowed to use
+the iAssign authoring tools to create activities with any iLM
+(like iGeom, iGraf, or iVprog, respectively to related to the subjects, Geometry, Functions and Programming).
+
+The main features of iAssign package are:
+ - The authoring tool to allow any teacher to easily prepare activities to students. Activities can be:
+   + an exercise (the student must send an answer, and if the iLM has automatic assessment, its results (right/wrong) is also registered);
+   + a test (the student does the activity, if iLM has automatic assessment, the student gets immediate feedback, but no data is recorded in Moodle's database);
+   + an example (the student can interact with the example, but nothing is recorded).
+ - Reports about students activities: 
+   + teachers can see, e.g., a survey or statistics about student's answers and can have quick access to any submited answer;
+   + the students have a survey of their activities (including their grades)
+ - Integration with general Moodle grades
+ - A filter that allows the insertion of iLM content into any (asynchronous) Moodle text.
+
+Besides, as the majority of Moodle modules, iAssign can export (as backup) one activity or a complete lesson (a set of activities).
+
+Note: This plugin is part of iAssign SET see more in https://moodle.org/plugins/browse.php?list=set&id=54
+
+.: Quick install instructions (to be used by the system administrator) :.
+
+0) Be sure you have (at least) Moodle 2.4 until Moodle 2.6 installed
+1) Be sure to have the latest language package, such as English (en), Portuguese (pt_br).
+2) Be sure to have the latest version of the module iAssign (see in https://github.com/leonidasbrandao/iAssign master)
+3) Unpack 'iAssign.2.1.x.zip' (or 'iAssign.2.1.x.tgz')
+4) Copy the 'iassign' module directory into the "mod" subdirectory of Moodle installation
+5) Under role "administrator", go to the 'Site administration' and click on 'Notifications'
+6) Have fun.
+
+
+.: What is news :.
+
+Considering the iAssign for Moodle 1.9, the new featuress in this version are:
+
+ - the teacher can produce a new interactive activity directly "on-line", using the new iLM editor (but is still possible to upload files);
+ - in a course with more than one teacher, it is now possible to use a local repository.
+ - See more in http://docs.moodle.org/en/iAssign.

+ * - v 1.5.2 2020/08/03
+ *     + Fixed 'ALTER TABLE' of 'iassign_submission.grade' from BIGINT(11) to REAL 
+ *     + New version of iHanoi 1.0.20200803
+ * - v 1.5.1 2020/05/28-30
+ *     + Avoid to update one iLM causing colision with other instance of the same iLM
+ * - v 1.4 2013/09/19
+ *     + Insert general fields for iassign statement (grade, timeavaliable, timedue, preventlate, test, max_experiment).
+ *     + Change index field 'name' in 'iassign_ilm' table to index field 'name,version'.
+ * - v 1.2 2013/08/30
