+# Sketch Testing Itself
+
+NOTE: This is an idea the Sketch developers are developing. We don't know if it works yet!
+
+Sketch can test itself, but it can be a bit tricky, especially when Sketch
+depends on Docker:
+
+# Manual Steps
+
+```
+# Create a throwaway SSH key
+ssh-keygen -t ed25519 -f ~/.ssh/sketch_test_key -P ""
+
+# Create a VM for Sketch to run Docker in
+limactl start --name=dockerhost --cpus=$(nproc) --memory=8 --plain --set='.ssh.localPort=2222' template://ubuntu
+
+# Add the key to the VM
+ssh -F "/Users/philip/.lima/dockerhost/ssh.config" lima-dockerhost tee -a .ssh/authorized_keys < /Users/philip/.ssh/sketch_test_key.pub
+```
+
+# What to tell Sketch
+
+* Mount your key with "-mount $HOME/.ssh/sketch_test_key:/sketch_test_key"
+* Configure DOCKER_HOST to host.docker.internal:2222 with the key above.
