 # Documentation
 
 ## Development
+Either link or clone the webknossos repository to `webknossos-libs/docs/src/webknossos`, e.g. with `git clone --depth 1 git@github.com:scalableminds/webknossos.git webknossos-libs/docs/src/webknossos` or by creating a symlink with `ln -s ../path/to/webknossos/docs src/webknossos`
+The symlink should look somewhat like this 
+```
+webknossos-libs/docs/src$ ls -l webknossos
+webknossos -> ../../../webknossos/docs
+```
 Run `./generate.sh` to open a live-reloading server rendering the documentation.
