+# 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 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.
+    
+    Your builds will take long.
+    
+    AppVeyor only grants a single worker VM - all jobs of the matrix are
+    executed sequentially. Each job will take around 10 minutes.
+    
+    The `matrix: / exclude:` setting can be used to reduce the number of
+    jobs. Check the [AppVeyor docs](https://www.appveyor.com/docs/build-configuration/#build-matrix)
+    for more ways to reduce the build matrix size.
+	
+ 6. Push your changes and check
+    [ci.appveyor.com](https://ci.appveyor.com/) for your build results.
