+# TA COMMENT
+
+Because we have a problem that when the students were deducted and wondered where they were deducted, then the 
+students asked ta one by one, causing difficulty in answer question. So we came up with this idea.
+
+This feature started out when we saw on github that when we reviewing the code we could tell which line of 
+code were bugs to the person that respomsible for that project. So we think this the way to solved that problem. But we can't
+do exactly like github. Then we have to change somthing to make it compatible with our projects.
+
+## Examples of use
+### how to write comment
+```python
+#>>> :start:
+
+### YOUR CODE ###
+
+#>>> :end: comment=good job
+```
+
+### how to read comment
+```python
+from ta_comment.main import ta_comment
+print(ta_comment(workpath)
+```
+
+### what you will get
+you will get comments in form of json follow this order studentId -> filename -> comment, lines
+```
+{
+   "123456789": [
+      {
+         "1.py": [
+            {
+               "comment": "good job",
+               "lines": {
+                  "15-23": "def create_ta_dir(path):\n    ta_path = os.path.join(path, \"ta\")\n    if os.path.exists(ta_path):\n        return False\n    else:\n        DirManagement().create_dir(ta_path,out=False)\n        return True\n"
+               }
+            },
+            {
+               "comment": "good job",
+               "lines": {
+                  "55-60": "def init_work_directory(path, workid) -> bool:\n    config_path = os.path.join(path, \"ta\", \"config.json\")\n    ta_path = os.path.join(path, \"ta\")\n    draft_path = os.path.join(path, \"ta\", \"draft.json\")\n"
+               }
+            }
+         ]
+      }
+ }
+```
+- we need to write down comment to student file
+- we have our own syntax (you can't change it)
+- all comment in student file will be read and send to server when we use `ta submit` (in case that you didn't use this feature on our project ignore this line)
