+# Apt & Yum Repository Maintenance
+## A maintainer's guide to managing Docker's package repos
+
+### How to clean up old experimental debs and rpms
+
+We release debs and rpms for experimental nightly, so these can build up.
+To remove old experimental debs and rpms, and _ONLY_ keep the latest, follow the
+steps below.
+
+1. Checkout docker master
+
+2. Run clean scripts
+
+```bash
+docker build --rm --force-rm -t docker-dev:master .
+docker run --rm -it --privileged \
+    -v /path/to/your/repos/dir:/volumes/repos \
+    -v $HOME/.gnupg:/root/.gnupg \
+    -e DOCKER_RELEASE_DIR=/volumes/repos \
+    docker-dev:master hack/make.sh clean-apt-repo clean-yum-repo
+```
+
+3. Re-sign the repo with your gpg key
+
+```bash
+./hack/make/sign-repos
+```
+
+4. Upload the changed repos to `s3` (if you host on s3)
+
+5. Purge the cache, PURGE the cache, PURGE THE CACHE!
+
+### How to get out of a sticky situation
+
+Sh\*t happens. We know. Below are steps to get out of any "hash-sum mismatch" or
+"gpg sig error" or the likes error that might happen to the apt repo.
+
+**NOTE:** These are apt repo specific, have had no experimence with anything similar
+happening to the yum repo in the past so you can rest easy.
+
+For each step listed below, move on to the next if the previous didn't work.
+Otherwise CELEBRATE!
+
+1. Purge the cache.
+
+2. Did you remember to sign the debs after releasing?
+
+Re-sign the repo with your gpg key:
+
+```bash
+./hack/make/sign-repos
+```
+
+Upload the changed repo to `s3` (if that is where you host)
+
+PURGE THE CACHE.
+
+3. Run Jess' magical, save all, only in case of extreme emergencies, "you are
+going to have to break this glass to get it" script.
+
+```bash
+docker build --rm --force-rm -t docker-dev:master .
+docker run --rm -it --privileged \
+    -v /path/to/your/repos/dir:/volumes/repos \
+    -v $HOME/.gnupg:/root/.gnupg \
+    -e DOCKER_RELEASE_DIR=/volumes/repos \
+    docker-dev:master hack/make.sh update-apt-repo
+```
+
+Re-sign the repo with your gpg key:
+
+```bash
+./hack/make/sign-repos
+```
+
+Upload the changed repo to `s3` (if that is where you host)
+
+PURGE THE CACHE.
