+### Tool to find C symbols, functions, declarations and definitions inside source code
+
+For this purpose it's possible to use a text-based tool called [Cscope](https://en.wikipedia.org/wiki/Cscope) together with a GUI (it can be either an application or a plugin for a text editor).
+
+#### Download / Installation
+
+* Download and install cscope with `pacman -S cscope`  
+Windows users must download the Windows version of cscope from https://code.google.com/archive/p/cscope-win32/downloads since the mingw version generates broken indices and put it into the main xonotic repo directory.
+
+* Download and install a cscope GUI or a plugin for your text editor / IDE. For example for jEdit there is a plugin called [CscopeFinder](http://plugins.jedit.org/plugins/?CscopeFinder).
+
+* Copy [cscope_createindex.sh](uploads/17c725e19be8f4935c30c2506e168405/cscope_createindex.sh) into the main xonotic repo directory.  
+
+#### Usage
+
+* Run `cscope_createindex.sh` to build cscope indices for both game (QC code) and Darkplaces (C code). This step must be repeated every time you do some code changes.  
+The indices can now be used to browse code confortably with the cscope GUI of your choice.
