 ## Web Search
 It's possible to search the web directly from Dashy, which might be useful if you're using Dashy as your start page. This can be done by typing your query as normal, and then pressing <kbd>⏎</kbd>. Web search options are configured under `appConfig.webSearch`.
 
-#### Setting Search Engine
+### Setting Search Engine
 Set your default search engine using the `webSearch.searchEngine` property. This defaults to DuckDuckGo. Search engine must be referenced by their key, the following providers are supported:

 You can also use a custom search engine, that isn't included in the above list (like a self-hosted instance of [Whoogle](https://github.com/benbusby/whoogle-search) or [Searx](https://searx.github.io/searx/)). Set `searchEngine: custom`, and then specify the URL (plus query params) to you're search engine under `customSearchEngine`.

-#### Setting Opening Method
+### Setting Opening Method
 In a similar way to opening apps, you can specify where you would like search results to be opened. This is done under the `openingMethod` attribute, and can be set to either  `newtab`, `sametab` or `workspace`. By default results are opened in a new tab.
 
-#### Disabling Web Search
+### Using Bangs
+An insanely useful feature of DDG is [Bangs](https://duckduckgo.com/bang), where you type a specific character combination at the start of your search query, and it will be redirected the that website, such as '!w Docker' will display the Docker wikipedia page. Dashy has a similar feature, enabling you to define your own custom bangs to redirect search results to a specific app, website or search engine.
+
+This is done under the `searchBangs` property, with a list of key value pairs. The key is what you will type, and the value is the destination, either as an identifier or a URL with query parameters.  
+
+For example:
+
+```yaml
+appConfig:
+  webSearch:
+    searchEngine: 'duckduckgo'
+    openingMethod: 'newtab'
+    searchBangs:
+      /r: reddit
+      /w: wikipedia
+      /s: https://whoogle.local/search?q=
+      /a: https://www.amazon.co.uk/s?k=
+      ':wolf': wolframalpha
+      ':so': stackoverflow
+      ':git': github
+```
+
+Note that bangs begging with `!` or `:` must be surrounded them in quotes
+
+### Disabling Web Search
 Web search can be disabled, by setting `disableWebSearch`, for example:
 
 ```yaml
