+## To automatically deploy pdfs to GitHub release
+* We will generate a GitHub OAuth key so Travis can push to your releases, with the important difference (compared to just gettting it via GitHub settings) that it's encryped so you can push it safely.
+* (Windows) [Download ruby](https://rubyinstaller.org/downloads/) and at at end of the installation make sure to install MSYS including development kit.
+* Run `gem install travis --no-rdoc --no-ri` to install the Travis Command-line Tool.
+* Remove the `deploy` section in the `.travis.yml` or use `--force` in the next command.
+* Replace everything below your encryped api key with
+```
+  file:
+  - ./_build/nameofmytexfile.pdf
+  skip_cleanup: true
+  on:
+    tags: true
+    branch: master
+```
+* If you are ready to release, just tag and push.
