 By default the `gfortran` executable is assumed to be found in the path. In order to use a different one or if it can't be found in the path you can point the extension to use a custom one with the `fortran.gfortranExecutable` setting.
+
 ```
 {
     "fortran.gfortranExecutable": '/usr/local/bin/gfortran-4.7',
 }
 ```
+
 If you want to pass extra options to the `gfortran` executable or override the default one, you can use the setting `fortran.linterExtraArgs`. By default `-Wall` is the only option.
+
 ```
 {
     "fortran.linterExtraArgs": ['-Wall'],
 }
 ```
 
+You can configure what kind of symbols will appear in the symbol list by using
+
+```
+{
+    "fortran.symbols": [ "function", "subroutine"]
+}
+```
+
+The available options are
+
+* "function"
+* "subroutine"
+* "variable"
+* "module" (not supported yet)
+* "program" (not supported yet)
+
+and by default only functions and subroutines are shown

 ## Error swiggles
+
 To trigger code validations you must save the file first.
 
 ## Requirements
+
 For the linter to work you need to have `gfortran` on your path, or wherever you configure it to be.
+
 ## Issues
+
 Please report any issues and feature request on the github repo [here](https://github.com/krvajalmiguelangel/vscode-fortran-support/issues/new)
+
 ## Notice
+
 The syntax highlight support was imported from [TextMate bundle](https://github.com/textmate/fortran.tmbundle)
 
 The idea of using gfortran cames from this awesome [fortran plugin](https://github.com/315234/SublimeFortran) for Sublime Text.
