+# Tagging Minijail releases
+
+* Choose a new-ish, stable-ish commit (i.e. not one that implements a completely
+new feature).
+
+* Find the latest tag:
+`minijail$ git tag -l "linux-v*"`
+
+* Tag the commit with the next version number:
+`minijail$ git tag -a linux-v<N+1> <commit>`
+
+* Push the tag:
+`minijail$ git push aosp linux-v<N+1>`
+
+We will tag a new release ~monthly at the beginning of the month.
