+
+# Welcome
+
+You've landed. The next 1–2 days are about getting you off the ground:
+the shell, Git, and how things work here. Sixteen blocks, one battle,
+then you're cleared for Python.
+
+This module gives you the bare minimum tools to write code, save your
+work, and ship it. Every command you learn here will reappear, in some
+form, every day for the rest of the program.
+
+## What You'll Do
+
+- Walk the file system from a blank prompt
+- Make, move, and read files
+- Write your first shell script
+- Configure Git and make your first commits
+- Push your work to GitHub and open your first pull request
+- Pair with another cadet to close out the module
+
+## Pace
+
+Roughly 10–12 hours of focused work. Some cadets finish in a day, some
+take two. Either is fine. Do not skip blocks — the checkpoint catches
+gaps.
