Your First Day as a Developer: Set Up Your Laptop the Safe Way

#beginners #git #career #productivity

It's your first morning. Your laptop is new, your team chat is busy, and someone says, "Get the project running today." Now what?

If you are looking at junior software developer jobs in the USA, this first-week task comes up almost everywhere, so DevGrid Staffing LLC put this short notebook together.

Check this first

Open a terminal. A terminal is a window where you type commands instead of clicking.
Check that Git is installed. Git is a tool that saves every version of your code, so you can go back if something breaks. Type:
```
git --version
```
If you see a version number, you're ready. If not, ask your team how they install tools.

Tell Git who you are. This puts your name on your work:

git config --global user.name "Your Name"
git config --global user.email "you@yourcompany.com"

Use your work email, not a personal one.

Do this next

Copy the project to your laptop. This is called "cloning." Your team will give you the link:
```
git clone <project-link>
```
Read the README first. The README is a file at the top of the project that explains what it is and how to set it up. Follow its setup steps in order, one at a time.
Run the tests before you change anything. Tests are small checks that make sure the code works. The README usually says how to run them. If they already fail before you touch anything, tell your team. That's useful news, not your mistake.
Ask where the contribution guide is. Many teams keep a file, often called CONTRIBUTING.md, or a wiki page with their rules for making changes. Read it before your first change.
When you're ready to change something, follow your team's pull request process. In short, you make your own branch (git checkout -b my-fix, or git switch -c my-fix in newer Git), save your change, and send it for review the way your team asks.

A small worked example

Say the README tells you to install the tools and then run the tests. You do both, and one step fails because a tool version is different on your laptop.

You write down the exact error message.
You check the README and the contribution guide for a fix.
If you can't find one, you post the error in the team chat and say which step you were on.

Your project is not running yet, but you've done the right thing. You didn't guess, you didn't change code to "make it work," and your team can now help you fast. Often this small problem leads to your first real fix: updating the README so the next new person doesn't get stuck.

Safe habits for week one

Change nothing until the project runs and you know which tests pass and which already fail.
Keep notes of every setup step that confused you.
Ask early. A question on day one saves hours on day three.

One thing to try today

Open any project you have, find its README, and follow the setup steps exactly as written. Write down every step that was unclear. That list is your first gift to a new team.
