However I don't own big servers and also don't want to run a relay from my home.

Probably, if you already use Tor from your home, and you have an external IP address, or may do port forwarding for a web server, you can easy help Tor with a middle relay, not an exit relay. This is simpler than even deploying a web mirror.

Meaning, your relay will not be banned by Google or any other companies who dislike Tor exit nodes.

Simple configuration:

# cat > /usr/local/etc/tor/torrc << EOF SocksPort 9050 Log notice file /usr/local/var/log/tor/notices.log RunAsDaemon 1 DataDirectory /usr/local/var/lib/tor ControlPort 9051 ORPort 9001 Nickname relay RelayBandwidthRate 1 MB RelayBandwidthBurst 5 MB ContactInfo anonymous anonymous@mail.com DirPort 9030 ExitPolicy reject *:* EOF

You can specify the relay bandwidth to gain optimal speed for your connection.

ExitPolicy reject *:* - set your relay as a middle in the Tor network. That way you increase the security of Tor network. In my humble opinion, this is the best way to help the Tor project, if you only have an Internet connection.

Start your relay with this configuration:
