+## Student
 
-@todo: How does a student submit his solution through the web app
+Student is a default role used in web application every newly registered user
+has it. As a student you have a quite limited range what to do in ReCodEx.
+Generally you can only submit your solutions of exercises in some particular
+groups. These groups should correspond to courses you attent at college.
 
-@todo: When the results are ready and what the results mean and what to
-do about them, when the user is convinced, that his solution is correct
-although the results say different
+### Join group and start solving assignments
 
-@todo: Describe the comments thread behavior (public/private comments),
-who else can see the comments, how notifications work (*not implemented
-yet*!).
+To be able to submit solutions you have to be member of the right group. Groups
+as such has hierarchy and belongs to some particular instance which you chose
+during registration. That is why if you want to join group you have to visit
+your instance link located in sidebar. After that you will be redirected
+instance detail page.
+
+In there you can see some description of intance and most importantly in "Groups
+hierarchy" box there can be found hierarchical list of all public groups in
+instance. Please note that groups with plus sign are collapsable and can be
+further extended. If you successfully located instance which you would like to
+join continue by clicking on "See group's page" link.
+
+**Note:** Some groups can be marked as private these groups are not visible in
+ hierarchy and cannot be joined by students themselves. Management of students
+ is then in the hands of supervisors.
+
+On the group detail page there multiple things which might concern you. First
+one is brief overview with information describing the group, there is list with
+supervisors and also hierarchy of subgroups. Most importantly there is
+"Student's dasboard" section. This section contains list of assignments and list
+of fellow students. If supervisors of groups allowed students to see each others
+statistics there will also be points which particular students gained.
+
+In the "Assignments" box on the group detail page there is list of assigned
+exercises which are students supposed to solve. Assignments are displayed with
+their names and deadlines. There are two deadlines, the first one means that
+till this datetime student will receive full amount of points in case of
+successful solution. Second deadline does not have to be set but if it is, then
+number of points which are gainable for successful solution within first and
+second deadline can be different.
+
+If you follow assignment link it will lead you to assignment detail page. In
+there you can found all possible details which might interest you. There are of
+course particular deadlines but also limit of submissions which you can make and
+full-range description of assignment. Description of assignment can be localized
+and you can switch between all language variants in tab like box.
+
+Further on the page you can found "Submitted solutions" box where list of
+submissions can be found with links to result details. But most importantly
+there is "Submit new solution" button on the assignment page which makes it
+possible to submit solution of the assignment.
+
+After clicking on submit button, dialog window should show up. In here you can
+upload files representing your solution, you can even add some notes to your
+supervisor if you thing they are needed. After you successfully uploaded all
+files necessary for the right execution of your solution then click on "Submit
+your solution" button and let ReCodEx do its thing.
+
+During execution ReCodEx backend might send to your browser evaluation progress
+state which will be displayed in another dialog window. When whole execution is
+finished then "See the results" button will appear and you can look at the
+results of your solution.
+
+On the results details page there are lot of information. Apart assignment
+description which is not connected to your results you can found here when the
+solution was submitted and by whom (supervisor can submit solution on your
+behalf), further there are files which were uploaded on submission and most
+importantly "Evaluation details" and "Test results".
+
+Evalation details contains overall results of your solution. There are
+information such as if solution was provided before deadlines if the evaluation
+process succesfully finished or if compilation succeeded. After that you can
+find a lot of numbers, most important one is the last one "Total score" where
+first number is your score and second one the maximum number of points.
+Interestingly the first number in total score can be higher than second one,
+that is because of "Bonus points" item above. If your solution is nice and
+supervisor will notice it he/she can assign you additional points for effort.
+
+In test results box you can find table of results from particular exercise test
+cases. In columns you can find these information:
+
+- test case overall result, yes/no option
+- test case name
+- percentage of correctness of this particular test
+- evaluation status, if test was successfully executed or failed
+- memory limit, if supervisor allowed it then percentual memory usage is
+  displayed
+- time limit, if supervisor allowed it then percentual time usage is displayed
+
+New feature of web application is "Comments and notes" box where you can
+communicate with your supervisors or just write random private notes to your
+submission. Adding note is quite simple you just write it to text field in the
+bottom of box and click on "Send" button. Note the lock image underneath, by
+click on it you can set visibility of the comment.
+
+If you think your solution is correct but ReCodEx evaluated as wrong one. You
+may consider to use comments system described above, but for now there are no
+notifications which will alert supervisors in case of new comments. So please
+use another mechanism to contact your supervisor.
