 - Add a new track
+    - See `soa.tracks.python` for an example of how to set up a track.
     - We assume the track is called 'mytrack' and has 2 tasks in it.
     - Go to `soa/tracks` and create a folder 'mytrack'
-    - Create a file `soa/tracks/mytrack/__init__.py` with contents
-      ```python
-      from soa.tracks.core import Track
-
-      class MyTrack(Track):
-        slug = 'mytrack'
-        title = 'My Track'
-        description = 'Absolutely mine'
-      ```
+    - Create a file `soa/tracks/mytrack/__init__.py` with contents about your track.
     - Create a file `soa/tracks/mytrack/1.md` and put the contents of your first task there.
-    - Create a file `soa/tracks/mytrack/2.md` and put the contents of your first task there.
+    - Create a file `soa/tracks/mytrack/2.md` and put the contents of your second task there.
     - You can add forms in the task markdown files to accept user answers and mark them as done. For example:
       ```md

-    - Any text inside `code` tags with class `code_checker` is used to verify the correct value for the input by the same name as the function.
-    - For example here, the value of the input with name `answer` will be passed to the function called `answer` that we have defined.
+    - The function to verify form answers is assigned to `MyTrack.tasks_meta[<taskslug>]['check']['answer']`.
     - Once you are done, run `python -m soa --test-tracks` to make sure that your changes are ok. If something fails, your markdown is probably faulty.
-        - Don't add useless spaces/new lines for the python code part.
-        - Don't add spaces at the ends of lines.
 - Add permissions to a user
     - `echo '[email protected] permission_string' | python -m soa --housekeeping add_perm`
 - Run any housekeeping function
