+# Stacks: Atomic Services using Docker Compose

+
+### Get a Stack (from source with Git)
+```sh
+STACK=ai
+git clone -n --depth=1 --filter=tree:0 https://gitea.jafner.tools/Jafner/Jafner.net.git /tmp/repo
+cd /tmp/repo
+git sparse-checkout set --no-cone homelab/stacks/$STACK
+git checkout
+mv homelab/stacks/$STACK $HOME/stacks/$STACK
+rm -rf /tmp/repo
+```
+
+This will clone the stack from the repo into a tmp directory, extract the stack to `~/stacks/$STACK`, and then delete the temp clone.
