+# web-search plugin
+
+This plugin adds aliases for searching with Google, Wiki, Bing, YouTube and other popular services.
+
+Open your `~/.zshrc` file and enable the `web-search` plugin:
+
+```zsh
+plugins=( ... web-search)
+```
+
+## Usage
+
+You can use the `web-search` plugin in these two forms:
+
+- `web_search <context> <term> [more terms if you want]`
+- `<context> <term> [more terms if you want]`
+
+For example, these two are equivalent:
+
+```zsh
+$ web_search google oh-my-zsh
+$ google oh-my-zsh
+```
+
+Available search contexts are:
+
+| Context               | URL                                             |
+| --------------------- | ----------------------------------------------- |
+| `bing`                | `https://www.bing.com/search?q=`                |
+| `google`              | `https://www.google.com/search?q=`              |
+| `brs` or `brave`      | `https://search.brave.com/search?q=`            |
+| `yahoo`               | `https://search.yahoo.com/search?p=`            |
+| `ddg` or `duckduckgo` | `https://www.duckduckgo.com/?q=`                |
+| `sp` or `startpage`   | `https://www.startpage.com/do/search?q=`        |
+| `yandex`              | `https://yandex.ru/yandsearch?text=`            |
+| `github`              | `https://github.com/search?q=`                  |
+| `baidu`               | `https://www.baidu.com/s?wd=`                   |
+| `ecosia`              | `https://www.ecosia.org/search?q=`              |
+| `goodreads`           | `https://www.goodreads.com/search?q=`           |
+| `qwant`               | `https://www.qwant.com/?q=`                     |
+| `givero`              | `https://www.givero.com/search?q=`              |
+| `stackoverflow`       | `https://stackoverflow.com/search?q=`           |
+| `wolframalpha`        | `https://wolframalpha.com/input?i=`             |
+| `archive`             | `https://web.archive.org/web/*/`                |
+| `scholar`             | `https://scholar.google.com/scholar?q=`         |
+| `ask`                 | `https://www.ask.com/web?q=`                    |
+| `youtube`             | `https://www.youtube.com/results?search_query=` |
+| `deepl`               | `https://www.deepl.com/translator#auto/auto/`   |
+| `dockerhub`           | `https://hub.docker.com/search?q=`              |
+| `npmpkg`              | `https://www.npmjs.com/search?q=`               |
+| `packagist`           | `https://packagist.org/?query=`                 |
+| `gopkg`               | `https://pkg.go.dev/search?m=package&q=`        |
+| `chatgpt`             | `https://chatgpt.com/?q=`                       |
+| `reddit`              | `https://www.reddit.com/search/?q=`             |
+| `ppai`                | `https://www.perplexity.ai/search/new?q=`       |
+
+Also there are aliases for bang-searching DuckDuckGo:
+
+| Context | Bang |
+| ------- | ---- |
+| `wiki`  | `!w` |
+| `news`  | `!n` |
+| `map`   | `!m` |
+| `image` | `!i` |
+| `ducky` | `!`  |
+
+### Custom search engines
+
+If you want to add other search contexts to the plugin, you can use the `$ZSH_WEB_SEARCH_ENGINES` variable.
+Set it before Oh My Zsh is sourced, with the following format:
+
+```zsh
+ZSH_WEB_SEARCH_ENGINES=(
+    <context> <URL>
+    <context> <URL>
+)
+```
+
+where `<context>` is the name of the search context, and `<URL>` a URL of the same type as the search contexts
+above. For example, to add `reddit`, you'd do:
+
+```zsh
+ZSH_WEB_SEARCH_ENGINES=(reddit "https://www.reddit.com/search/?q=")
+```
+
+These custom search engines will also be turned to aliases, so you can both do `web_search reddit <query>` or
+`reddit <query>`.
