+# Example
+
+Resume f8 @ 512 on Laion-HR
+
+```
+sbatch scripts/slurm/resume_512/sbatch.sh
+```
+
+# Reuse
+
+To reuse this as a template, copy `sbatch.sh` and `launcher.sh` somewhere. In
+`sbatch.sh`, adjust the lines
+
+```
+#SBATCH --job-name=stable-diffusion-512cont
+#SBATCH --nodes=24
+```
+
+and the path to your `launcher.sh` in the last line,
+
+```
+srun bash /fsx/stable-diffusion/stable-diffusion/scripts/slurm/resume_512/launcher.sh
+```
+
+In `launcher.sh`, adjust `CONFIG` and `EXTRA`. Maybe give it a test run with
+debug flags uncommented and a reduced number of nodes.
