 The latest stable version of AtChem2 can be downloaded from the [Releases page](https://github.com/AtChem/AtChem2/releases). After installing the required dependencies using the scripts in the `tools/install/` directory, copy the file `tools/install/Makefile.skel` to the _Main Directory_ and rename it `Makefile`. Set the variables `CVODELIB`, `OPENLIBMDIR` and `FRUITDIR` in `Makefile` to the paths of CVODE, openlibm and (if installed) FRUIT. To compile the model using the example chemical mechanism, execute the command:
 
 ```
-./build/build_atchem2.sh ./mcm/mechanism_test.fac
+./build/build_atchem2.sh ./model/mechanism.fac
 ```
 
 The build script converts the chemical mechanism from the FACSIMILE format (`mechanism_test.fac`) to a Fortran-compatible format, and generates the shared library `mechanism.so` in the `model/configuration/` directory. After the build process is completed, an executable file called `atchem2` is created in the _Main Directory_.
