+# Forward Domain (Beta)
+
+This services forwards domains using 301 HTTP redirects.
+
+Possible scenarios:
+
++ Forward non-www to www URLs or inversely
++ Forward old URLs to new URLs
+
+Why using this service?
+
++ No coding required
++ No hosting required
++ No registration required
++ Completely anonymous
++ Completely free
+
+How it is possible?
+
++ Point your domain to us using CNAME or A/AAAA records
++ Tell us where to forward using TXT records
++ We handle HTTPS certificates for you
+
+## Get Started
+
+To forward from `www.old.com` to `old.com`, add these records to your DNS:
+
+```
+old.com   IN    CNAME   r.forwarddomain.net
+old.com   IN    TXT     forward-domain=https://new.net/*
+old.com   IN    TXT     forward-domain-cert-maintainer=<your email address>
+```
+
+> IMPORTANT: replace `<your email address>` with your email address!
+
+Because CNAME can't be used in apex domains, you can use A/AAAA records.<br>
+To forward from `old.com` to `new.net`, add these records to your DNS:
+
+```
+old.com   IN    A       206.189.61.89
+old.com   IN    AAAA    2a03:b0c0:3:d0::13a8:c001
+old.com   IN    TXT     forward-domain=https://new.net/*
+old.com   IN    TXT     forward-domain-cert-maintainer=<your email address>
+```
+
+> BETA service notice: IP addresses can change anytime (with notice).
+
+## FAQ
+
+### Why email address?
+
+This is required in order to sign HTTPS certificates.<br>
+You can omit it but HTTPS redirects will not work.
+
+### Is it really free?
+
+Forwarding domains should be easy to setup.<br>
+I use this internally for [domcloud.io](https://domcloud.io).<br>
+
+### How can I check redirects will work?
+
+This service uses Google's [Public DNS Resolver](https://dns.google).<br>
+Once first accessed, values will be cached for a day.<br>
+For right now there's no way to flush the cache sorry.
+
+### Why it loads slowly?
+
+It only slow at first time because it has to sign HTTPS certificates.
+
+### How can I support this service?
+
+Star our repo and spread the word, please :)
