+You `don't have to be root` then, although `it is recommended`.

-Which does 3 jobs:
-* create and copy `le.sh` to your home dir:  `~/.le`
-All the certs will be placed in this folder.
-* create alias : `le.sh=~/.le/le.sh` and `le=~/.le/le.sh`. 
-* create everyday cron job to check and renew the cert if needed.
+Advanced Installation:  https://github.com/Neilpang/acme.sh/wiki/How-to-install

-After install, you must close current terminal and reopen again to make the alias take effect.
+The installer will perform 3 actions:
+
+1. Create and copy `acme.sh` to your home dir (`$HOME`):  `~/.acme.sh/`.
+All certs will be placed in this folder.
+2. Create alias for: `acme.sh=~/.acme.sh/acme.sh`. 
+3. Create everyday cron job to check and renew the cert if needed.
+
+Cron entry example:
+
+```bash
+0 0 * * * "/home/user/.acme.sh"/acme.sh --cron --home "/home/user/.acme.sh" > /dev/null
+```
+

+```
 
-# Just issue a cert:
-Example 1:
-Only one domain:
-```
-le issue   /home/wwwroot/aa.com    aa.com 
+# 2. Just issue a cert:
+
+**Example 1:** Single domain.
+
+```bash

+```bash
+acme.sh --issue -d example.com -d www.example.com -d cp.example.com -w /home/wwwroot/example.com 
 ```

-First argument `/home/wwwroot/aa.com` is the web root folder, You must have `write` access to this folder.
+The parameter `/home/wwwroot/example.com` is the web root folder. You **MUST** have `write access` to this folder.

-Second argument "aa.com" is the main domain you want to issue cert for.
+Second argument **"example.com"** is the main domain you want to issue cert for.
+You must have at least a domain there.

-Third argument is the additional domain list you want to use. Comma separated list,  which is Optional.
+You must point and bind all the domains to the same webroot dir: `/home/wwwroot/example.com`.

-You must point and bind all the domains to the same webroot dir:`/home/wwwroot/aa.com`
+Generate/issued certs will be placed in `~/.acme.sh/example.com/`

-The cert will be placed in `~/.le/aa.com/`
+The issued cert will be renewed every **60** days automatically.

-The issued cert will be renewed every 80 days automatically.
+More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert

-# Install issued cert to apache/nginx etc.
-```
-le installcert  aa.com /path/to/certfile/in/apache/nginx  /path/to/keyfile/in/apache/nginx  /path/to/ca/certfile/apache/nginx   "service apache2|nginx reload"
+
+# 3. Install the issued cert to apache/nginx etc.
+
+After you issue a cert, you probably want to install/copy the cert to your nginx/apache or other servers you may be using.
+
+```bash
+acme.sh --installcert -d example.com \
+--certpath /path/to/certfile/in/apache/nginx  \
+--keypath  /path/to/keyfile/in/apache/nginx  \
+--capath   /path/to/ca/certfile/apache/nginx   \
+--fullchainpath path/to/fullchain/certfile/apache/nginx \
+--reloadcmd  "service apache2|nginx reload"
 ```

-Install the issued cert/key to the production apache or nginx path.
+Only the domain is required, all the other parameters are optional.

-The cert will be renewed every 80 days by default (which is configurable), Once the cert is renewed, the apache/nginx will be automatically reloaded by the command: `service apache2 reload` or `service nginx reload`
+Install/copy the issued cert/key to the production apache or nginx path.

+The cert will be `renewed every **60** days by default` (which is configurable). Once the cert is renewed, the apache/nginx will be automatically reloaded by the command: `service apache2 reload` or `service nginx reload`.

-# Use Standalone server to issue cert (requires you be root/sudoer, or you have permission to listen tcp 80 port):
-Same usage as all above,  just give `no` as the webroot.
-The tcp `80` port must be free to listen, otherwise you will be prompted to free the `80` port and try again.
+# 4. Use Standalone server to issue cert

-```
-le issue    no    aa.com    www.aa.com,cp.aa.com
+**(requires you be root/sudoer, or you have permission to listen tcp 80 port)**
+
+The tcp `80` port **MUST** be free to listen, otherwise you will be prompted to free the `80` port and try again.
+
+```bash
+acme.sh --issue --standalone -d example.com -d www.example.com -d cp.example.com
 ```

-# Use Apache mode (requires you be root/sudoer, since it is required to interact with apache server):
-If you are running a web server, apache or nginx, it is recommended to use the Webroot mode.
-Particularly,  if you are running an apache server, you can use apache mode instead. Which doesn't write any file to your web root folder.
+More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert

-Just set string "apache" to the first argument, it will use apache plugin automatically.
+# 5. Use Standalone tls server to issue cert

-```
-le  issue  apache  aa.com   www.aa.com,user.aa.com
-```
-All the other arguments are the same with previous.
+**(requires you be root/sudoer, or you have permission to listen tcp 443 port)**

+acme.sh supports `tls-sni-01` validation.

-# Use DNS mode:
-Support the latest dns-01 challenge.
+The tcp `443` port **MUST** be free to listen, otherwise you will be prompted to free the `443` port and try again.

-```
-le  issue   dns   aa.com  www.aa.com,user.aa.com
+```bash
+acme.sh --issue --tls -d example.com -d www.example.com -d cp.example.com
 ```

-You will get the output like bellow:
+More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
+
+# 6. Use Apache mode
+
+**(requires you be root/sudoer, since it is required to interact with apache server)**
+
+If you are running a web server, apache or nginx, it is recommended to use the `Webroot mode`.
+
+Particularly, if you are running an apache server, you should use apache mode instead. This mode doesn't write any files to your web root folder.
+
+Just set string "apache" as the second argument, it will force use of apache plugin automatically.
+
+```
+acme.sh --issue --apache -d example.com -d www.example.com -d user.example.com
+```
+
+More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
+
+# 7. Use DNS mode:
+
+Support the `dns-01` challenge.
+
+```bash
+acme.sh --issue --dns -d example.com -d www.example.com -d user.example.com
+```
+
+You should get the output like below:
+
 ```
 Add the following txt record:
-Domain:_acme-challenge.aa.com
+Domain:_acme-challenge.example.com
 Txt value:9ihDbjYfTExAYeDs4DBUeuTo18KBzwvTEjUnSwd32-c

 Add the following txt record:
-Domain:_acme-challenge.www.aa.com
+Domain:_acme-challenge.www.example.com
 Txt value:9ihDbjxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
-```

 Please add those txt records to the domains. Waiting for the dns to take effect.

-Then just retry with 'renew' command:
-
 ```
-le renew  aa.com
+
+Then just rerun with `renew` argument:
+
+```bash
+acme.sh --renew -d example.com
 ```

 Ok, it's finished.

+# 9. Issue ECC certificate:
+
+`Let's Encrypt` now can issue **ECDSA** certificates.

-# Issue ECC certificate:
-LetsEncrypt now can issue ECDSA certificate.
 And we also support it.

 Just set the `length` parameter with a prefix `ec-`.
+
 For example:

-Single domain:
-```
-le issue  /home/wwwroot/aa.com    aa.com   no      ec-256
+### Single domain ECC cerfiticate:
+
+```bash
+acme.sh --issue -w /home/wwwroot/example.com -d example.com --keylength  ec-256
 ```

-SAN multiple domains:
-```
-le issue  /home/wwwroot/aa.com    aa.com   www.aa.com,cp.aa.com    ec-256
+SAN multi domain ECC certificate:
+
+```bash
+acme.sh --issue -w /home/wwwroot/example.com -d example.com -d www.example.com --keylength  ec-256
 ```

 Please look at the last parameter above.

 Valid values are:

-1. ec-256 (prime256v1,  "ECDSA P-256")
-2. ec-384 (secp384r1,   "ECDSA P-384")
-3. ec-521 (secp521r1,   "ECDSA P-521", which is not supported by letsencrypt yet.)
+1. **ec-256 (prime256v1, "ECDSA P-256")**
+2. **ec-384 (secp384r1,  "ECDSA P-384")**
+3. **ec-521 (secp521r1,  "ECDSA P-521", which is not supported by Let's Encrypt yet.)**


+# 10. How to renew the cert

-#Under the Hood
+No, you don't need to renew the certs manually.  All the certs will be renewed automatically every **60** days.

-Speak ACME language with bash directly to Let's encrypt.
+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
+```
+
+# 11. How to upgrade `acme.sh`
+acme.sh is in developing, it's strongly recommended to use the latest code.
+
+You can update acme.sh to the latest code:
+```
+acme.sh --upgrade
+```
+
+You can enable auto upgrade:
+```
+acme.sh  --upgrade  --auto-upgrade
+```
+Then **acme.sh** will keep up to date automatically.
+
+Disable auto upgrade:
+```
+acme.sh  --upgrade  --auto-upgrade 0
+```
+
+# 12. Issue a cert from an existing CSR
+
+https://github.com/Neilpang/acme.sh/wiki/Issue-a-cert-from-existing-CSR
+
+
+# Under the Hood
+
+Speak ACME language using shell, directly to "Let's Encrypt".

+https://developer.godaddy.com/keys/
+
+Please Create a Production key, instead of a Test key.
+
+
+```
+export GD_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+
+export GD_Secret="asdfsdafdsfdsfdsfdsfdsafd"
+
+```
+
+Ok, let's issue cert now:
+```
+acme.sh   --issue   --dns dns_gd   -d example.com  -d www.example.com
+```
+
+The `GD_Key` and `GD_Secret`  will be saved in `~/.acme.sh/account.conf`, when next time you use cloudflare api, it will reuse this key.
+
+## Use PowerDNS embedded api to automatically issue cert
+
+We support PowerDNS embedded API integration.
+
+First you need to enable api and set your api-token in PowerDNS configuration.
+
+https://doc.powerdns.com/md/httpapi/README/
+
+```
+export PDNS_Url="http://ns.example.com:8081"
+export PDNS_ServerId="localhost"
+export PDNS_Token="0123456789ABCDEF"
+export PDNS_Ttl=60
+
+```
+
+Ok, let's issue cert now:
+```
+acme.sh   --issue   --dns dns_pdns   -d example.com  -d www.example.com
+```
+
+The `PDNS_Url`, `PDNS_ServerId`, `PDNS_Token` and `PDNS_Ttl` will be saved in `~/.acme.sh/account.conf`.
