-# Running a example in NEXT
+# Running an Example in NEXT
 
-To run a example in NEXT, you need to *cd* to an example path
-
-You also need a python interpeter
-
-For this, lets try the ColdCollapseGalaxy example
+To run an example in **NEXT**, first navigate to the example’s directory.  
+You will also need a Python interpreter installed.
 
+As a demonstration, let’s try the **ColdCollapseGalaxy** example:
 ```bash
-cd examples
-cd ColdCollapseGalaxy
-python coldcollapse.py
-../../next coldcollapse.txt 8 0.25 0.2 vtu
+    cd examples
+    cd ColdCollapseGalaxy
+    python coldcollapse.py
+    ../../next coldcollapse.txt 8 0.25 0.2 vtu
 ```
+### Explanation of the command
 
-Explaining the flags:
-
-- ../../next = Go up 2 directories (into project root) and run executable
-
-- coldcollapse.txt = The name of the specified "scenario" / "initial condition"
-
-- 8 = Set openmp (CPU) threads to 8, if your cpu has more, you can change it
-
-- 0.25 = Timestep, how fast the simulation will run
-
-- 0.2 = Caching interval, how fast NEXT would plot caching
-
-- vtu = Caching format, there is currently vtk|vtu
+- `../../next` → Move up two directories (to the project root) and run the NEXT executable  
+- `coldcollapse.txt` → The scenario / initial condition file  
+- `8` → Number of OpenMP (CPU) threads; adjust based on your CPU  
+- `0.25` → Timestep, controls how fast the simulation advances  
+- `0.2` → Dump interval, controls how often NEXT writes output  
+- `vtu` → Output format; options are `vtk` or `vtu`  
 
-Now, you can enjoy the simulation and exit with ctrl c / q
+Now you can enjoy the simulation.  
+To exit, press **Ctrl+C** or type **q** (then Enter).
