+Uploading from GitHub with Travis CI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is also possible to upload your DAPs directly from GitHub using
+`Travis CI <https://travis-ci.org/>`_ . Unfortunately you cannot do it via the ``deploy``
+statement, because DAPI is not yet supported there. But you can still do it with ``after_success``.
+Here is an example ``.travis.yml`` that will upload your DAP to DAPI on tagged commits only::
+
+  language: python # Use python here so you can install DevAssistant easily
+  python:
+  - '3.4' # Just one version is required, 3.4 is the latest
+  install:
+  - pip install devassistant 
+  - sudo apt-get install realpath # needed by the packing assistant
+  - da pkg install dap
+  script:
+  - da twk dap pack
+  - da pkg lint *.dap
+  
+  # Upload to DAPI on tagged commits from owner/dap-foo
+  after_success:
+  - if [ -n "$TRAVIS_TAG" ] && [ "$TRAVIS_PULL_REQUEST" == "false" ] &&
+       [ "$TRAVIS_REPO_SLUG" == "owner/dap-foo" ] && [ -n "$DAPI_TOKEN" ]; then
+        git config --global devassistant.dapi.token $DAPI_TOKEN;
+        da extra dap upload -d *.dap;
+    fi
+  
+  # This was generated by: travis encrypt DAPI_TOKEN=xxxxxxxxxxxxxxxxxxxx --add
