+# AppVeyor Scripts for EPICS Modules
+
+## Features
+
+ - Use different compilers (Visual Studio, MinGW)
+ - Use different VS versions (2008, 2010, 2012, 2013, 2015, 2017, 2019)
+ - Compile for Windows 32bit and 64bit
+ - Create static libraries or DLLs (plus the matching executables)
+ - Create optimized or debug builds
+
+## How to Use these Scripts
+
+ 1. Get an account on [AppVeyor](https://www.appveyor.com/), connect
+    it to your GitHub account and activate your support module's
+    repository. For more details, please see below and refer to the
+    [AppVeyor documentation](https://www.appveyor.com/docs/).
+
+ 2. Add the ci-scripts respository as a Git Submodule
+    (see [README](../README.md) one level above).
+
+ 3. Add settings files defining which dependencies in which versions
+    you want to build against
+    (see [README](../README.md) one level above).
+
+ 4. Create an AppVeyor configuration by copying one of the examples into
+    the root directory of your module.
+    ```
+    $ cp .ci/appveyor/.appveyor.yml.example-full .appveyor.yml
+    ```
+
+ 5. Edit the `.appveyor.yml` configuration to include the jobs you want
+    AppVeyor to run.
+
+    AppVeyor automatically creates a build matrix with the following axes:
+    1. `configuration:` \
+    Select static or dynamic (DLL) as well as regular or debug builds.
+    2. `platform:` \
+    Select 32bit or 64bit processor architecture.
+    3. `environment: / matrix:` \
+    List of environment variable settings. Each list element (starting with
+    a dash) is one step on the axis of the build matrix. \
+    Set `CMP` to select the compiler: `mingw` for the native
+    [MinGW](http://mingw-w64.org/) GNU compiler, `vs2008` ...`vs2019` 
+    (options listed above) for the Microsoft Visual Studio compilers.
+
+    Your builds will take long. \
+    AppVeyor only grants a single worker VM - all jobs of the matrix are
+    executed sequentially. Each job will take between 6 and 15 minutes,
+    plus testing time.
+
+    The `matrix: / exclude:` setting can be used to reduce the number of
+    jobs. Check the [AppVeyor docs][appveyor.doc.matrix]
+    for more ways to reduce the build matrix size.
+    E.g., you can opt for not creating matrix axes for `configuration:`
+    and`platform:` by moving these configurations into the job lines
+    under `environment: / matrix:`.
+
+ 6. Push your changes and check
+    [ci.appveyor.com](https://ci.appveyor.com/) for your build results.
+
+## GitHub / AppVeyor Integration and Authentication
+
+### Security
+Enabling Two-Factor-Authentication (2FA) is always a good idea, for all 
+your web based services, including GitHub and AppVeyor. \
+Get an app for your phone (Authy works fine for me, but there are plenty),
+and your phone will generate one-time passwords to verify your identity
+to the service if required (e.g., when logging in from a new device).
+
+### Authentication
+You can use different ways and services to authenticate when you log into
+your AppVeyor account. The easiest way - at least when you're using the
+service with repositories on GitHub - is to use GitHub authentication.
+
+### GitHub Integration
+AppVeyor offers two ways to integrate with GitHub: through a GitHub
+application or through an OAuth application. GitHub applications are using
+the newer API, allow easier fine-grained access rights tuning and are
+preferred.
+
+The differences are mostly visible when you work with repositories under
+organizational GitHub accounts: Using OAuth, AppVeyor always has the full
+rights of your personal GitHub account.
+GitHub applications on the other hand have separate instances and
+configuration for every organizational account you are using on GitHub.
+
+### Enabling Builds for your Repository
+On the 'Projects' tab of your AppVeyor web interface, create a new project.
+If the repository is not listed on the project creation page,
+verify the Integration settings. Most of the relevant configuration
+is taken from GitHub and has to be set up there.
+
+### AppVeyor Account Sharing
+You can always invite other AppVeyor users to have access to an AppVeyor
+account, forming a team. Such additional shared accounts are a way to make
+the AppVeyor limits (e.g., one parallel builder per account) more manageable.
+
+## Known Issues
+
+#### Build Worker Images
+The AppVeyor documentation on build worker images doesn't seem to fully
+describe the way things are handled internally.
+
+The tested and suggested reproducible way of defining the build worker image
+is shown in the example configuration files:
+
+ - Set the default image using the `image:` tag.
+ - Override the image for specific jobs by setting the
+   `APPVEYOR_BUILD_WORKER_IMAGE` environment variable.

+## Caches
+
+Travis keeps the caches separate for different jobs. As soon as the job
+description (in the `.travis.yml` configuration file) or its environment
+settings change (adding a space character is enough), the cache is different
+and will be rebuilt when the job runs.
+
+This also means that changing a value inside a setup file will _not_
+invalidate the cache - in that case you will have to manually delete the cache
+through the Travis web interface. (Or add a space character in the job
+configuration.)
+
+Caches are automatically removed after approx. four weeks.
+Your jobs will have to rebuild them once in a while.
