> Past Project Reference <[Enhance visualized RISC-V simulation](https://hackmd.io/@sysprog/H1hH_y_Syx)>

## Project Preparation
### Create Final Project Folder and Create New Git

mkdir Final_Project
cd Final_Project

After `Final_Project` folder is created, we can add `README.md` file inside the folder and have a initial commit in `main` branch.

git add .
git commit -m "Initial Commit"
git branch -M main

### Merge Ares Project
Here is [Ares](https://github.com/ldlaur/ares.git) project on Github and we can merge it into the git of our final project.
We can type following comments:

git subtree add --prefix=ares https://github.com/ldlaur/ares.git master --squash

> Explaination of this comment:
> 1. **subtree:** It can help us easily merge projects which already had git.
> 2. **--prefix=ares:** It can help us create a folder named `ares` and put the git folder inside it. <font color="red">**[The folder we want to create needs to be empty, otherwise it won't work.]**</font>
> 3. **https ~:** The directory or url we want to download from.
> 4. **master:** The branch we want to download from.
> 5. **--squash:** This identifier will only show the latest commit or the commit we assign. If we don't use this identifier, it will merge all the commits together.

> The detail of `git subtree` can see the document -> [Git Subtree](https://git-memo.readthedocs.io/en/latest/subtree.html).
> Or the note from Bosh Kuo -> [Git Subtree：多專案整合的實用技巧](https://notes.boshkuo.com/docs/DevTools/Git/git-subtree).

Ares is a web which can dynamically show the RV32I instruction between the memory.
The original web of Ares -> [Ares Web](https://ares-sim.github.io/).

### Merge emulsiV Project
Here is [emulsiV](https://github.com/ESEO-Tech/emulsiV) project on Github and we can merge it into the git of out final project.
We can type following comments:

git subtree add --prefix=ares https://github.com/ESEO-Tech/emulsiV master --squash

### Push it to Our Github 1141_CA_Fianl_Project

git remote add origin https://github.com/ianrwan/1141_CA_Final_Project.git
git push -u origin main

**Github of our final project -> [1141_CA_Final_Project](https://github.com/ianrwan/1141_CA_Final_Project.git).**
