 On the first run, setup everything (this may take some time — we're compiling
 glibc and its whole testsuite here):
 
-```

   ./setup_env.sh

 (this is not strictly necessary, but will help you debug stuff):
 
-```
+```bash
   source ./env
 ```
 
 You may then either run a single test,

 ```
 
 or run the whole testsuite
 
-```
+```bash
   ./run_all_tests.sh
