+Complete roundtrip for caravel_user_project
+===========================================
+
+1. To start the project you need to first create an empty Git project on Github and make sure your repo is public and includes a README
+
+2. Open your Terminal. Create an empty folder to use as your Caravel workspace, and navigate to it.
+
+.. code:: bash
+
+ # Create a directory and call it anything you want
+ mkdir -p caravel_tutorial
+
+ # navigate into the directory
+ cd caravel_tutorial
+
+3. Clone caravel_user_project and setup the git environment as follows
+
+.. code:: bash
+
+ # Make sure that ``caravel_example`` matches the empty github repo name in step 1
+ git clone -b mpw-5 https://github.com/efabless/caravel_user_project caravel_example
+ cd caravel_example
+ git remote rename origin upstream
+
+ # You need to put your empty github repo URL from step 1
+ git remote add origin <your github repo URL>
+
+ # Create a new branch, you can name it anything
+ git checkout -b <my_branch>
+ git push -u origin <my_branch>
+
+4. Now that your git environment is setup, it's time to setup your local environment
+
+.. code:: bash
+
+ # to install caravel-lite into your caravel_user_project
+ # you can install full caravel (not recommended) use ``export CARAVEL_LITE=0``
+ make install
+
+ # The default for the management core is litex, to install the pico version use
+ export MCW=pico
+ # To install the management core for simulation
+ make install_mcw
+
+
+
+ # To clone the management core pico for simulation
+ git clone git@github.com:efabless/caravel_pico.git
+
+ # Install openlane for hardening your project
+ # make sure to change <directory_name> with the directory you created in step 1
+ # in this case it is caravel_tutorial
+ export OPENLANE_ROOT=~/<directory_name>/openlane # you need to export this whenever you start a new shell
+ make openlane
+
+ # Build the pdk
+ # make sure to change <directory_name> with the directory you created in step 1
+ # in this case it is caravel_tutorial
+ export PDK_ROOT=~/<directory_name>/pdks # you need to export this whenever you start a new shell
+ make pdk
+
+5. Now you can start hardening your design, for example
+
+.. code:: bash
+
+ make user_proj_example
+ make user_project_wrapper
+
+6. To run simulation on your design
+
+.. code:: bash
+
+ make simenv
+ # you can run RTL/GL simulations by using
+ export SIM=RTL
+ # OR
+ export SIM=GL
+
+ # you can then run the simulations using
+ make verify-<testbench-name>
+
+ # for example
+ make verify-io_ports
+
+7. To run the precheck locally
+
+.. code:: bash
+
+ make precheck
+ make run-precheck
+
+17. You are done! now go to www.efabless.com to submit your project!
