+# Generic Travis CI build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want in the 'jobs'.
+# 2. If you have more than include/, src/, test/, example/, examples/, or
+#    tools/ directories, modify your Travis CI project and add the environment
+#    variable DEPINST.  For example if your build uses code in "bench/" and
+#    "fog/" directories, then set DEPINST to the following:
+#        --include bench --include fog
+# 3. If you want to enable Coverity Scan, you need to provide the environment
+#    variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
+#    your github settings.
+# 4. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the scripts will do everything else for you.

+
+* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-algorithm)
+* [Report bugs](https://github.com/boostorg/algorithm/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt).
+* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[algorithm]` tag at the beginning of the subject line.

+# Generic Appveyor build script for boostorg repositories
+# See: https://github.com/boostorg/boost-ci/
+#
+# Instructions for customizing this script for your library:
+#
+# 1. Customize the compilers and language levels you want.
+# 2. If you have more than include/, src/, test/, example/, examples/,
+#    benchmark/ or tools/ directories, set the environment variable DEPINST.
+#    For example if your build uses code in "bench/" and "fog/" directories:
+#      - DEPINST: --include bench --include fog
+# 3. Enable pull request builds in your boostorg/<library> account.
+#
+# That's it - the script will do everything else for you.
