+There are two scripts to aid users in adding or removing domains to the whitelist or blacklist. 
+
+The scripts will first parse `whitelist.txt` or `blacklist.txt` for any changes, and if any additions or deletions are detected, it will reload dnsmasq so that they are effective immediately.
+
+Each script accepts the following parameters:
+
+<table>
+  <tbody>
+      <tr>
+         <th><code>[domain]</code></th>
+         <td>Fully qualified domain name you wish to add or remove. You can pass any number of domains.</td>
+      </tr>     
+      <tr>
+         <th><code>-d</code></th>
+         <td>Removal mode. Domains will be removed from the list, rather than added</td>
+      </tr>     
+      <tr>
+         <th><code>-nr</code></th>
+         <td>Add or removed domains, but don't reload dnsmasq</td>
+      </tr>
+      <tr>
+         <th><code>-f</code></th>
+         <td>Force dnsmasq to reload even if the script did not detect any changes to the list</td>
+      </tr>
+      <tr>
+         <th><code>-q</code></th>
+         <td>Quiet mode. Console output is minimal. Useful for calling from another script (see <code>gravity.sh</code>)</td>
+      </tr>
+   </tbody>
+</table>
+
+Domains passed are parsed by the script to ensure they are valid domains. If a domain is invalid it will be ignored.
+
+
+#####Example `whitelist.sh` usages
+
+<table>
+  <tbody>
+      <tr>
+         <th><code>whitelist.sh domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the whitelist and reload dnsmasq.</td>
+      </tr>     
+      <tr>
+         <th><code>whitelist.sh -nr domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the whitelist, but do not reload dnsmasq.</td>
+      </tr>     
+      <tr>
+         <th><code>whitelist.sh -f domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the whitelist and force dnsmasq to reload</td>
+      </tr>
+   </tbody>
+</table>
+
+To remove domains from the whitelist:
+Add `-d` as an additional argument (e.g `whitelist.sh -d domain1 [domain2...]`)
+
+#####Example `blacklist.sh` usages
+<table>
+  <tbody>
+      <tr>
+         <th><code>blacklist.sh domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the blacklist and reload dnsmasq.</td>
+      </tr>     
+      <tr>
+         <th><code>blacklist.sh -nr domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the blacklist, but do not reload dnsmasq.</td>
+      </tr>     
+      <tr>
+         <th><code>blacklist.sh -f domain1 [domain2...]</code></th>
+         <td>Attempt to add one or more domains to the blacklist and force dnsmasq to reload</td>
+      </tr>
+   </tbody>
+</table>
+
+To remove domains from the blacklist:
+Add `-d` as an additional argument (e.g `blacklist.sh -d domain1 [domain2...]`)
