+
+## Parts
+### Avatar
+`avatar` can be used to get the avatar of the user.  
+If the user doesn't have an avatar this is just 
+```html
+<h1>domain.shakecities/</h1>
+```
+If the user does have an avatar this is
+
+```html
+<img src='avatar-url' width='200vw' height='200vw' style='border-radius: 50%;margin-right: 5px;'>
+```
+
+### HNSChat
+If the user has a HNSChat name set this will return
+```html
+<a href='https://hns.chat/#message:username' target='_blank'>
+    <img src='hns_icon' width='20px' height='20px' style='margin-right: 5px;'>
+    username/
+</a>
+```
+
+### Location
+If the user has a location set this will return
+```html
+<img src='location_icon' width='20px' height='30px' style='margin-right: 5px;'>
+location
+```
+
+### Email
+If the user has a email set this will return
+```html
+<a href='mailto:email@example'>
+    <img src='email_icon' width='30px' height='20px' style='margin-right: 5px;margin-left:-10px;'>
+    email@example
+</a>
+```
+
+### Footer (footer)
+This is the Shakecities footer. It will always be the same "Powered by Shakecities"
+
+
+## Text Placeholders
+### Main domain (main_domain)
+`main_domain` can be used to get the main domain of the site e.g. shakecities.com
+
+### Data (data)
+`data` can be used to get the data of the site.  
+This is the main body
+
+
+
+## Crypto Address Placeholders
+### Icons
+These are the icons for the crypto addresses.  
+There are 2 versions of each icon. One with a contrast to the foreground colour and one without.
+
+These return the path to the image of the icon (eg. `assets/img/HNS.png`)
+
+They are as follows:
+- hns_icon
+- hns_icon_invert
+- btc_icon
+- btc_icon_invert
+- eth_icon
+- eth_icon_invert
+
+### Full parts
+These are the full parts for the crypto addresses.  
+They return both the icon and the address.
+
+For example `hns` returns
+```html
+<img src='hns_icon' width='20px' height='20px' style='margin-right: 5px;'>hs1...
+```
+
+The list of full parts are:
+- hns
+- btc
+- eth
+- hns_invert
+- btc_invert
+- eth_invert
+
+
+### Address only
+
+These are plain text addresses without the icon.  
+Eg. `hns_address` returns
+```html
+hs1...
+```
+
+They are as follows:
+- hns_address
+- btc_address
+- eth_address
+
+
