 tar xf v8.0.0.tar.gz
+```
+
+Then, NAMD can be built with the following options:
+

 cd charm-8.0.0
 ./build charm++ multicore-linux-x86_64 --with-production
-cd multicore-linux-x86_64/tests/charm++/megatest
-make -j 4
-./megatest +p4 
 cd ../../../../..
 
 ./config Linux-x86_64-g++ --charm-arch multicore-linux-x86_64
 
 cd Linux-x86_64-g++
-make -j 4
+make
+```
