 By default mta-sts-daemon allows its multiple instances to share same port (on Linux/FreeBSD/Windows). Therefore, restart or upgrade of daemon can be performed seamlessly. Set of unit files for systemd in [contrib/](contrib/) directory implements "reload" by mean of running backup instance when main instance is getting restarted.

 ## MTA-STS Daemon configuration
 
-See [configuration man page](https://github.com/Snawoot/postfix-mta-sts-resolver/blob/master/man/mta-sts-daemon.yml.5.adoc) and [config\_examples/](https://github.com/Snawoot/postfix-mta-sts-resolver/tree/master/config_examples) directory. Default config location is: `/etc/mta-sts-daemon.yml`, but it can be overriden with command line option `-c FILE`.

 ### Systems without Python 3.5+
 
-Some people may find convenient to install latest python from source into `/opt` directory. This way you can have separate python installation not interferring with system packages by any means. Download latest python source from [python.org](https://www.python.org/), unpack and run in unpacked source directory:

 ### Building virtualenv
 
-Run `make` in project directory in order to build virtualenv. As result of it, new directory `venv` shall appear. `venv` contains interpreter and all required dependencies, i.e. encloses package with depencencies in separate environment. It is possible to specify alternative path where virtualenv directory shall be placed. Specify VENV variable for `make` command. Example:
