+#######################################################
+
+This directory contains the files that you will use to build and run
+the CS:APP Bomb Lab. The Bomb Lab teaches students principles of
+machine-level programs, as well as general debugger and reverse
+engineering skills.
+
+***********
+1. Overview
+***********
+
+----
+1.1. Binary Bombs
+----
+A "binary bomb" is a Linux executable C program that consists of six
+"phases." Each phase expects the student to enter a particular string
+on stdin.  If the student enters the expected string, then that phase
+is "defused."  Otherwise the bomb "explodes" by printing "BOOM!!!".
+The goal for the students is to defuse as many phases as possible.
+
+----
+1.2. Solving Binary Bombs
+----
+In order to defuse the bomb, students must use a debugger, typically
+gdb or ddd, to disassemble the binary and single-step through the
+machine code in each phase. The idea is to understand what each
+assembly statement does, and then use this knowledge to infer the
+defusing string.  Students earn points for defusing phases, and they
+lose points (configurable by the instructor, but typically 1/2 point)
+for each explosion. Thus, they quickly learn to set breakpoints before
+each phase and the function that explodes the bomb. It's a great
+lesson and forces them to learn to use a debugger.
+
+
+*******************
+1. Bomb Terminology
+*******************
+
+LabID: Each instance (offering) of the lab is identified by a unique
+name, e.g., "f12" or "s13", that the instructor chooses. Explosion and
+diffusions from bombs whose LabIDs are different from the current
+LabID are ignored. The LabID must not have any spaces.
+
+BombID: Each bomb in a given instance of the lab has a unique
+non-negative integer called the "bombID."
+
+Notifying Bomb: A bomb can be compiled with a NOTIFY option that
+causes the bomb to send a message each time the student explodes or
+defuses a phase. Such bombs are called "notifying bombs." 
+
+Quiet Bomb: If compiled with the NONOTIFY option, then the bomb
+doesn't send any messages when it explodes or is defused. Such bombs
+are called "quiet bombs."
+
+We will also find it helpful to distinguish between custom and
+generic bombs:
+
+Custom Bomb: A "custom bomb" has a BombID > 0, is associated with a
+particular student, and can be either notifying or quiet. Custom
+notifying bombs are constrained to run on a specific set of Linux
+hosts determined by the instructor. On the other hand, custom quiet
+bombs can run on any Linux host.
+
+Generic Bomb: A "generic bomb" has a BombID = 0, isn't associated with
+any particular student, is quiet, and hence can run on any host.

+# CMU 15-213: Bomb Lab
+
+You are given a pre-built binary bomb. It has six phases. Each phase expects a specific input line; if any line is wrong the bomb explodes. Your job is to reverse engineer the binary and write the correct six lines to a file called `solution.txt`.
+
+The binary and supporting materials are in the starter directory:
+
+- `bomb`: the ELF64 binary bomb
+- `bomb.c`: the main driver (does not reveal the phase internals)
+- `README.bomb`: background about the lab
+
+## Task
+
+1. Work inside `/workspace`.
+2. Recover the correct input for each of the six phases of the bomb.
+3. Write the six inputs in order, one per line, to `solution.txt`.
+4. Do not modify the starter artifacts (`bomb`, `bomb.c`, `README.bomb`).
+
+The grading script will run `./bomb solution.txt` and expects the bomb to report success without ever printing `BOOM!!!`.
+
+## Useful commands
+
+- `strings bomb` to scan embedded text
+- `objdump -d bomb | less` to disassemble
+- `gdb ./bomb` to step through phases (set breakpoints on `phase_1`…`phase_6`)
+- `./bomb` to run interactively during testing
+
+## What is evaluated
+
+- `solution.txt` exists and has at least six lines
+- Starter files are unchanged
+- `./bomb solution.txt` completes without exploding and prints "Congratulations! You've defused the bomb!"
+
+Secret phases are not required. Focus only on phases 1–6.
