+# Travis Notes for Administrators
+
+Administrators: Are PRs taking > 1 hr to run through Travis? If you look at the Travis logs is it building `riscv-tools`?
+
+This is because someone committed a PR to `master` which bumped `riscv-tools` and the master cache needs to be updated.
+This is the procedure to follow to get 
+things fast again. We don't generally build on merges to master, just PRs.
+
+##
+
+1. Wait for your PR that you want to merge to go green. This will take a long time.
+2. On Travis, click `More Options -> Caches` on the upper right.
+3. Click `Delete all Repository Caches`. 
+4. Click `More Options->Settings`
+5. On the `General Settings` section, switch the `Build Branch Updates` toggle to `ON`.
+6. perform your PR's merge to master. This will cause the master cache to build `riscv-tools`.
+7. Once the merge commit goes green on Jenkins, switch the `Build Branch Updates` toggle to `OFF`.
