+# 11. How to renew the issued certs
+
+No, you don't need to renew the certs manually. All the certs will be renewed automatically every **60** days.
+
+However, you can also force to renew any cert:
+
+```
+acme.sh --renew -d example.com --force
+```
+
+or, for ECC cert:
+
+```
+acme.sh --renew -d example.com --force --ecc
+```
+
+
+# 12. How to upgrade `acme.sh`
+
+acme.sh is in constant development, so it's strongly recommended to use the latest code.
+
+You can update acme.sh to the latest code:
+
+```
+acme.sh --upgrade
+```
+
+You can also enable auto upgrade:
+
+```
+acme.sh --upgrade --auto-upgrade
+```
+
+Then **acme.sh** will be kept up to date automatically.
+
+Disable auto upgrade:
+
+```
+acme.sh --upgrade --auto-upgrade 0
+```

+# Using deploy api
+
+Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
+
+Here are the scripts to deploy the certs/key to the server/services.
+
+## 1. Deploy the certs to your cpanel host.
+
+(cpanel deploy hook is not finished yet, this is just an example.)
+
+
+
+Then you can deploy now:
+
+```sh
+export DEPLOY_CPANEL_USER=myusername
+export DEPLOY_CPANEL_PASSWORD=PASSWORD
+acme.sh --deploy -d example.com --deploy-hook cpanel
+```
+
+## 2. Deploy ssl cert on kong proxy engine based on api.
+
+Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
+Currently supports Kong-v0.10.x.
+
+```sh
+acme.sh --deploy -d ftp.example.com --deploy-hook kong
+```
+
+## 3. Deploy the cert to remote server through SSH access.
+
+(TODO)
+
+## 4. Deploy the cert to local vsftpd server.
+
+```sh
+acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
+```
+
+The default vsftpd conf file is `/etc/vsftpd.conf`,  if your vsftpd conf is not in the default location, you can specify one:
+
+```sh
+export DEPLOY_VSFTPD_CONF="/etc/vsftpd.conf"
+
+acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
+```
+
+The default command to restart vsftpd server is `service vsftpd restart`, if it doesn't work, you can specify one:
+
+```sh
+export DEPLOY_VSFTPD_RELOAD="/etc/init.d/vsftpd restart"
+
+acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
+```
+
+## 5. Deploy the cert to local exim4 server.
+
+```sh
+acme.sh --deploy -d ftp.example.com --deploy-hook exim4
+```
+
+The default exim4 conf file is `/etc/exim/exim.conf`,  if your exim4 conf is not in the default location, you can specify one:
+
+```sh
+export DEPLOY_EXIM4_CONF="/etc/exim4/exim4.conf.template"
+
+acme.sh --deploy -d ftp.example.com --deploy-hook exim4
+```
+
+The default command to restart exim4 server is `service exim4 restart`, if it doesn't work, you can specify one:
+
+```sh
+export DEPLOY_EXIM4_RELOAD="/etc/init.d/exim4 restart"
+
+acme.sh --deploy -d ftp.example.com --deploy-hook exim4
+```
+
+## 6. Deploy the cert to OSX Keychain
+
+```sh
+acme.sh --deploy -d ftp.example.com --deploy-hook keychain
+```

+
+
+## 6. Use OVH/kimsufi/soyoustart/runabove API to automatically issue cert
+
+https://github.com/Neilpang/acme.sh/wiki/How-to-use-OVH-domain-api
+
+
+## 7. Use nsupdate to automatically issue cert
+
+First, generate a key for updating the zone
+```
+b=$(dnssec-keygen -a hmac-sha512 -b 512 -n USER -K /tmp foo)
+cat > /etc/named/keys/update.key <<EOF
+key "update" {
+    algorithm hmac-sha512;
+    secret "$(awk '/^Key/{print $2}' /tmp/$b.private)";
+};
+EOF
+rm -f /tmp/$b.{private,key}
+```
+
+Include this key in your named configuration
+```
+include "/etc/named/keys/update.key";
+```
+
+Next, configure your zone to allow dynamic updates.
+
+Depending on your named version, use either
+```
+zone "example.com" {
+    type master;
+    allow-update { key "update"; };
+};
+```
+or
+```
+zone "example.com" {
+    type master;
+    update-policy {
+        grant update subdomain example.com.;
+    };
+}
+```
+
+Finally, make the DNS server and update Key available to `acme.sh`
+
+```
+export NSUPDATE_SERVER="dns.example.com"
+export NSUPDATE_KEY="/path/to/your/nsupdate.key"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_nsupdate -d example.com -d www.example.com
+```
+
+The `NSUPDATE_SERVER` and `NSUPDATE_KEY` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+
+## 8. Use LuaDNS domain API

+
+```
+export LUA_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export LUA_Email="xxxx@sss.com"
+```
+
+To issue a cert:
+```
+acme.sh --issue --dns dns_lua -d example.com -d www.example.com
+```
+
+The `LUA_Key` and `LUA_Email` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+
+## 9. Use DNSMadeEasy domain API
+
+Get your API credentials at https://cp.dnsmadeeasy.com/account/info
+
+```
+export ME_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export ME_Secret="qdfqsdfkjdskfj"
+```
+
+To issue a cert:
+```
+acme.sh --issue --dns dns_me -d example.com -d www.example.com
+```
+
+The `ME_Key` and `ME_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+
+## 10. Use Amazon Route53 domain API
+
+https://github.com/Neilpang/acme.sh/wiki/How-to-use-Amazon-Route53-API
+
+```
+export  AWS_ACCESS_KEY_ID=XXXXXXXXXX
+export  AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXX
+```
+
+To issue a cert:
+```
+acme.sh --issue --dns dns_aws -d example.com -d www.example.com
+```
+
+The `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 11. Use Aliyun domain API to automatically issue cert
+
+First you need to login to your Aliyun account to get your API key.
+[https://ak-console.aliyun.com/#/accesskey](https://ak-console.aliyun.com/#/accesskey)
+
+```
+export Ali_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export Ali_Secret="jlsdflanljkljlfdsaklkjflsa"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_ali -d example.com -d www.example.com
+```
+
+The `Ali_Key` and `Ali_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 12. Use ISPConfig 3.1 API
+
+This only works for ISPConfig 3.1 (and newer).
+
+Create a Remote User in the ISPConfig Control Panel. The Remote User must have access to at least `DNS zone functions` and `DNS txt functions`.
+
+```
+export ISPC_User="xxx"
+export ISPC_Password="xxx"
+export ISPC_Api="https://ispc.domain.tld:8080/remote/json.php"
+export ISPC_Api_Insecure=1
+```
+If you have installed ISPConfig on a different port, then alter the 8080 accordingly.
+Leaver ISPC_Api_Insecure set to 1 if you have not a valid ssl cert for your installation. Change it to 0 if you have a valid ssl cert.
+
+To issue a cert:
+```
+acme.sh --issue --dns dns_ispconfig -d example.com -d www.example.com
+```
+
+The `ISPC_User`, `ISPC_Password`, `ISPC_Api`and `ISPC_Api_Insecure` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 13. Use Alwaysdata domain API
+
+First you need to login to your Alwaysdata account to get your API Key.
+
+```sh
+export AD_API_KEY="myalwaysdataapikey"
+```
+
+Ok, let's issue a cert now:
+
+```sh
+acme.sh --issue --dns dns_ad -d example.com -d www.example.com
+```
+
+The `AD_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused
+when needed.
+
+## 14. Use Linode domain API
+
+First you need to login to your Linode account to get your API Key.
+[https://manager.linode.com/profile/api](https://manager.linode.com/profile/api)
+
+Then add an API key with label *ACME* and copy the new key.
+
+```sh
+export LINODE_API_KEY="..."
+```
+
+Due to the reload time of any changes in the DNS records, we have to use the `dnssleep` option to wait at least 15 minutes for the changes to take effect.
+
+Ok, let's issue a cert now:
+
+```sh
+acme.sh --issue --dns dns_linode --dnssleep 900 -d example.com -d www.example.com
+```
+
+The `LINODE_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 15. Use FreeDNS
+
+FreeDNS (https://freedns.afraid.org/) does not provide an API to update DNS records (other than IPv4 and IPv6
+dynamic DNS addresses).  The acme.sh plugin therefore retrieves and updates domain TXT records by logging
+into the FreeDNS website to read the HTML and posting updates as HTTP.  The plugin needs to know your
+userid and password for the FreeDNS website.
+
+```sh
+export FREEDNS_User="..."
+export FREEDNS_Password="..."
+```
+
+You need only provide this the first time you run the acme.sh client with FreeDNS validation and then again
+whenever you change your password at the FreeDNS site.  The acme.sh FreeDNS plugin does not store your userid
+or password but rather saves an authentication token returned by FreeDNS in `~/.acme.sh/account.conf` and
+reuses that when needed.
+
+Now you can issue a certificate.
+
+```sh
+acme.sh --issue --dns dns_freedns -d example.com -d www.example.com
+```
+
+Note that you cannot use acme.sh automatic DNS validation for FreeDNS public domains or for a subdomain that
+you create under a FreeDNS public domain.  You must own the top level domain in order to automatically
+validate with acme.sh at FreeDNS.
+
+## 16. Use cyon.ch
+
+You only need to set your cyon.ch login credentials.
+If you also have 2 Factor Authentication (OTP) enabled, you need to set your secret token too and have `oathtool` installed.
+
+```
+export CY_Username="your_cyon_username"
+export CY_Password="your_cyon_password"
+export CY_OTP_Secret="your_otp_secret" # Only required if using 2FA
+```
+
+To issue a cert:
+```
+acme.sh --issue --dns dns_cyon -d example.com -d www.example.com
+```
+
+The `CY_Username`, `CY_Password` and `CY_OTP_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 17. Use Domain-Offensive/Resellerinterface/Domainrobot API
+
+You will need your login credentials (Partner ID+Password) to the Resellerinterface, and export them before you run `acme.sh`:
+```
+export DO_PID="KD-1234567"
+export DO_PW="cdfkjl3n2"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_do -d example.com -d www.example.com
+```
+
+## 18. Use Gandi LiveDNS API
+
+You must enable the new Gandi LiveDNS API first and the create your api key, See: http://doc.livedns.gandi.net/
+
+```
+export GANDI_LIVEDNS_KEY="fdmlfsdklmfdkmqsdfk"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_gandi_livedns -d example.com -d www.example.com
+```
+
+## 19. Use Knot (knsupdate) DNS API to automatically issue cert
+
+First, generate a TSIG key for updating the zone.
+
+```
+keymgr tsig generate acme_key algorithm hmac-sha512 > /etc/knot/acme.key
+```
+
+Include this key in your knot configuration file.
+
+```
+include: /etc/knot/acme.key
+```
+
+Next, configure your zone to allow dynamic updates.
+
+Dynamic updates for the zone are allowed via proper ACL rule with the `update` action. For in-depth instructions, please see [Knot DNS's documentation](https://www.knot-dns.cz/documentation/).
+
+```
+acl:
+  - id: acme_acl
+    address: 192.168.1.0/24
+    key: acme_key
+    action: update
+
+zone:
+  - domain: example.com
+    file: example.com.zone
+    acl: acme_acl
+```
+
+Finally, make the DNS server and TSIG Key available to `acme.sh`
+
+```
+export KNOT_SERVER="dns.example.com"
+export KNOT_KEY=`grep \# /etc/knot/acme.key | cut -d' ' -f2`
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_knot -d example.com -d www.example.com
+```
+
+The `KNOT_SERVER` and `KNOT_KEY` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 20. Use DigitalOcean API (native)
+
+You need to obtain a read and write capable API key from your DigitalOcean account. See: https://www.digitalocean.com/help/api/
+
+```
+export DO_API_KEY="75310dc4ca779ac39a19f6355db573b49ce92ae126553ebd61ac3a3ae34834cc"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_dgon -d example.com -d www.example.com
+```
+
+## 21. Use ClouDNS.net API
+
+You need to set the HTTP API user ID and password credentials. See: https://www.cloudns.net/wiki/article/42/
+
+```
+export CLOUDNS_AUTH_ID=XXXXX
+export CLOUDNS_AUTH_PASSWORD="YYYYYYYYY"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_cloudns -d example.com -d www.example.com
+```
+
+## 22. Use Infoblox API
+
+First you need to create/obtain API credentials on your Infoblox appliance.
+
+```
+export Infoblox_Creds="username:password"
+export Infoblox_Server="ip or fqdn of infoblox appliance"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_infoblox -d example.com -d www.example.com
+```
+
+Note: This script will automatically create and delete the ephemeral txt record.
+The `Infoblox_Creds` and `Infoblox_Server` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+
+## 23. Use VSCALE API
+
+First you need to create/obtain API tokens on your [settings panel](https://vscale.io/panel/settings/tokens/).
+
+```
+VSCALE_API_KEY="sdfsdfsdfljlbjkljlkjsdfoiwje"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_vscale -d example.com -d www.example.com
+```
+
+##  24. Use Dynu API
+
+First you need to create/obtain API credentials from your Dynu account. See: https://www.dynu.com/resources/api/documentation
+
+```
+export Dynu_ClientId="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+export Dynu_Secret="yyyyyyyyyyyyyyyyyyyyyyyyy"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_dynu -d example.com -d www.example.com
+```
+
+The `Dynu_ClientId` and `Dynu_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 25. Use DNSimple API
+
+First you need to login to your DNSimple account and generate a new oauth token.
+
+https://dnsimple.com/a/{your account id}/account/access_tokens
+
+Note that this is an _account_ token and not a user token. The account token is
+needed to infer the `account_id` used in requests. A user token will not be able
+to determine the correct account to use.
+
+```
+export DNSimple_OAUTH_TOKEN="sdfsdfsdfljlbjkljlkjsdfoiwje"
+```
+
+To issue the cert just specify the `dns_dnsimple` API.
+
+```
+acme.sh --issue --dns dns_dnsimple -d example.com
+```
+
+The `DNSimple_OAUTH_TOKEN` will be saved in `~/.acme.sh/account.conf` and will
+be reused when needed.
+
+If you have any issues with this integration please report them to
+https://github.com/pho3nixf1re/acme.sh/issues.
+
+## 26. Use NS1.com API
+
+```
+export NS1_Key="fdmlfsdklmfdkmqsdfk"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_nsone -d example.com -d www.example.com
+```
+
+# Use custom API
+
+If your API is not supported yet, you can write your own DNS API.
+
+Let's assume you want to name it 'myapi':
 
 1. Create a bash script named `~/.acme.sh/dns_myapi.sh`,
-2. In the scrypt, you must have a function named `dns_myapi_add()`. Which will be called by acme.sh to add dns records.
-3. Then you can use your api to issue cert like:
+2. In the script you must have a function named `dns_myapi_add()` which will be called by acme.sh to add the DNS records.
+3. Then you can use your API to issue cert like this:
 
 ```
-acme.sh  --issue  --dns  dns_myapi  -d aa.com  -d www.aa.com
+acme.sh --issue --dns dns_myapi -d example.com -d www.example.com
 ```
 
 For more details, please check our sample script: [dns_myapi.sh](dns_myapi.sh)
