 ## How to build
 
 ### Getting the source codes
 
 Download the latest source codes by
 
-	$ git clone https://github.com/j-otsuki/SpM.git spm.src
+    $ git clone https://github.com/j-otsuki/SpM.git spm.src
 
-Then, the source codes are downloaded in the directory ``spm.src``.

 ### Using Cmake
 
-Build with cmake command is done in a separate directory, e.g. ``spm.build``.

-* ``samples/boson``  # sample for bosonic spectrum
+* `samples/fermion`  # sample for fermionic spectrum (data in the article)
+* `samples/boson`  # sample for bosonic spectrum
 
 A script file, `run.sh`, is provided to run through the program.
 Enter into the directory `samples/fermion`, and execute the script by
 
     $ ./run.sh
 
-You may need to change the path to ``SpM.out`` in the script.
-If succeeded, results including graphs in eps format are created in ``output`` directory.
