 # Developer Guidelines
 
 ## First Steps
 
 1. Read the API high-level/overview information at:
    - [`libgraphtheory`](libgraphtheory)
-   - [`stc`](src)
+   - [`src`](src)
 2. Compile:
    - have a look at the `CMake` output!
 3. Run Tests and Run Application:
    - `make tests`
 
 ## API Documentation
 
 The Rocs API is reasonable good documentation in most parts of Rocs,
 especially in the RocsCore library. You can either
-[create the doxygen files by hand](http://techbase.kde.org/Development/Tools/apidox)
-or use the nightly updated references at https://api.kde.org.

 Rocs is a Graph Theory IDE for everybody interested in designing and analyzing
 graph algorithms (e.g., lecturers, students, researchers). For all these users,
 Rocs provides an easy to use visual data structure editor and a powerful
 scripting engine to execute algorithms.
 
 [Rocs at KDE.org](https://www.kde.org/applications/education/rocs).
 
 ## Features
 
-- Canvas for Graph Drawing
-- IDE for Graph related Programming, using Javascript as it's main language,
-  plus the graph library
-- Data Structures are extensible from the scripting interface, so you can do
-  anything you want.
