Most people think the barrier to using GitHub is learning to code.
It’s not.
The real barrier is a handful of tiny, boring, “nobody ever explained this” skills that make the difference between:
bookmarking a repo and never touching it
actually running it and getting value out of it
You don’t need to become a developer.
You just need to know how to run things.
This guide covers the smallest set of skills that will unlock a huge percentage of GitHub projects for you—fast.
#1: Learn how to clone a repo
This is straightforward and easy.
Download GitHub Desktop and log in. Once there, choose File → Clone repository.
In the popup that appears, click on the URL tab on the far right. Copy and paste the URL of the repo you want to clone and choose where you want to save it on your hard drive.
GitHub will download the repo as a folder on your computer, named after the repo.
#2: Download Python and Node.js
Go to https://www.python.org/downloads/ and download Python.
When installing, be sure to check the box next to “Add Python to PATH” so it will work from the command line.
Next, go to https://nodejs.org/en/download and download Node.js.
Done.
For repos that include lots of other code packages, we will be using:
npm (Node Package Manager) for JavaScript
pip (Python’s package installer) for Python
The fastest way to know what to use
If the repo you are working in contains a package.json file, you will be using npm.
If the repo contains requirements.txt instead, you will be using pip.
These files just list the extra code the project depends on.
#3: Learn the most basic ways to use Command Prompt
If you’re a Windows user, you have options. You can use Command Prompt, PowerShell, Git Bash, or others.
These are different shells, but most basic commands (like cd) work the same across them.
You can open Command Prompt by going to the Start menu and typing cmd.
It will open a black window with a file path listed, like:
C:\Windows\System32>
Move into your project folder
Since you’ve already cloned a repo, go to where you saved it on your hard drive.
Right-click the folder and choose Copy as path.
Return to Command Prompt and type:
cd "paste-your-path-here"
Then hit Enter.
Now you are in the correct folder to run commands for that project.
Running the project
Now that you have Python and Node.js installed, you can run the repo based on what it uses.
Look in the root folder for either:
package.json → use npm
requirements.txt → use pip
For npm (JavaScript projects)
These are the most common commands you’ll see:
npm install
npm run dev
(Some projects also use npm run build, but not all.)
Running npm run dev will usually give you a local URL like:
Open that in your browser to see the project running on your computer.
For pip (Python projects)
The main commands are:
pip install -r requirements.txt
python app.py
(Replace app.py with whatever file the project uses.)
On some systems, you may need to use:
python3 app.py
What happens when you run it?
Some Python projects will print output directly in the terminal
Others will open a browser window (especially apps built with tools like Streamlit)
How to know what command to run
Open the README file.
Look for a section called:
“Installation”
“Getting Started”
Then:
👉 Copy and paste the commands exactly
Don’t overthink it.
This is the part nobody tells you:
You don’t need to understand most of the code in a GitHub repo to use it.
You just need to know how to:
get it onto your computer
install what it depends on
run the right command
That’s it.
Once you have these basics down, GitHub stops being a wall of confusing files and starts becoming a library of tools you can actually use.
And the more you do this, the easier it gets—because most repos follow the same patterns over and over again.
You don’t need to become a programmer.
You just need to stop skipping this layer.
