Create Your First Repl 

You can choose a Blank Repl template to start:

You can get a shell to run your own commands:

Lets start with htop software. It will automatically install it then run it.

~/test$ htop
htop: command not installed, but was located via Nix.
Would you like to run htop from Nix and add it to your replit.nix file? [Yn]: Y
Adding htop to replit.nix
success
/nix/store/zkjmh1llrq0ssamd5lfxyz43s09vafhr-htop-3.0.5
Detected change in environment, reloading shell...
~/test$ 

Here is how the system looks like:

Your Repl project will be running in Google Cloud and the main host will be 8 cores wtih 64G RAM. All new REPL projects will be started from one server until it reaches the limitation, then start another new host server for new projects. As metnioned in previous section, free Repl will have 0.2-0.5 CPU, 512ram and 500MB storage. Need more, pay for it. 

By the way, although Replit provides SQLite database as well, for your dynamic site, it had better to use other site's free database, such as https://freedb.tech/ , which gives you a free 50MB MySQL db with root access.
