+### Local development example
+
+Here we setup to use our local build of the `juggler` library.
+First set some environment variables.
+```
+export JUGGLER_INSTALL_PREFIX=$HOME/stow/juggler
+export JUGGLER_DETECTOR=athena   # athena is the default
+export BEAMLINE_CONFIG=ip6       # ip6 is the default
+```
+
+
+```
+git@eicweb.phy.anl.gov:EIC/benchmarks/reconstruction_benchmarks.git && cd reconstruction_benchmarks
+git clone https://eicweb.phy.anl.gov/EIC/benchmarks/common_bench.git setup
+source setup/bin/env.sh && ./setup/bin/install_common.sh
+source .local/bin/env.sh && build_detector.sh
