+# CSE 3666 - Fall 2023
+
+This repo is for CSE 3666 in Fall 2023. We will use multiple platforms this semester.
+
+*   HuskyCT. Most of the course materials, including syllabus, schedule,
+    lecture slides, and homework assignments, will be posted in HuskyCT. We
+    will also use it for online quizzes.
+
+    Here is [the Blackboard help center for students](https://help.blackboard.com/Learn/Student)
+
+*   Gradescope. We will use Gradescope to grade most of the lab assignments and some homework questions.
+    The submission links will be created in HuskyCT. 
+
+    Here are the instructions for [submitting an assignment on
+    Gradescope](https://help.gradescope.com/article/ccbpppziu9-student-submit-work).
+
+*   This repo. Lab assignments will be posted here. The submission portals/links are in HuskyCT.
+
+*   iClicker. For lecture participations.
+
+*   Discord server. For online discussions. 
+
+*   [CSE 3666 supplementary materials in a public repo](https://github.com/zhijieshi/cse3666/tree/master)
+
+Your submitted work in lab, homework, quiz, exam, etc. should be clean and
+tidy. Always write good, concise comments in code.  
+
+When grading coding questions manually, we check the correctness but also the
+**quality**. For example, RISC-V idioms should be recognized and written
+properly. Some idioms are listed on [this
+page.](https://github.com/zhijieshi/cse3666/blob/master/rv-examples/risc-v-idioms.md)
+In addition, good code should be easy to read.
+
+## File storage
+
+**Important:** Save your files to cloud storage like OneDrive. Local 
+storage on lab computers or UConn AnyWare Desktop may be purged. 
+
+As of January 2023, UITS has enabled OneDrive on UConn Anyware Desktop. The
+File Explorer has a link (OneDrive - University of Connecticut) to the user's
+OneDrive folder. In PowerShell, the folder "OneDrive - University of Connecticut" is
+in the user's home directory. The files can also be accessed with the Web interace
+through [email.uconn.edu](https://email.uconn.edu/).
