 ## Prebuilt OGS-6 Docker images
 
-There are docker images provided on [Docker Hub](https://hub.docker.com/u/ogs6/) which include everything necessary to build OGS-6.
+There are docker images provided on [Docker Hub](https://hub.docker.com/u/ogs6/) which include everything necessary to build OGS-6. They are intended to be used by Jenkins. Do not use them for development as you will run into permission issues (when mounting your source code into the container: in the container you are the `jenkins` user which has other `uid` and `gid`).
 
-There are images for `gcc` and `clang`.
-
-E.g. to start developing OGS:
-
-```bash
-docker pull ogs6/gcc
-docker run --rm -t -i -v /path/to/ogs/source/on/host:/tmp/ogs ogs6/gcc
-```
+Use [Singularity container]({{< relref "singularity.pandoc" >}}) for development instead.
 
-You are now in the Docker container the ogs source code from your host computer mounted at `/usr/src/ogs`. Now you can build and run OGS:
-
-```bash
-cd /tmp
-mkdir build; cd build
-cmake ../ogs
-make ogs
-./bin/ogs
-```
+There are images for `gcc` and `clang`.
