+# Getting Started
+
+This page describes common use cases for creating redirect rules in the Redirect Web app.
+
+(You can also learn the details of rule settings on the [Redirect Rule](./redirect-rule.md) page.)
+
+
+## Case 1: Open another website
+
+Suppose you're addicted to Twitter, and you decide to meditate in Insight Timer whenever you accidentally open Twitter. Let's create a rule for that!
+
+### Step 1. Set up "Redirect From"
+
+First, you should set up the **Redirect From** section in the **Edit Rule** screen in the app. The targets are URLs starting with `https://twitter.com/`.
+
+In this case, you can specify the following pattern with the **[Wildcard](redirect-rule?id=wildcard)** mode:
+
+```
+https://twitter.com/*
+```
+
+In the Wildcard mode, `*` means it matches anything (= zero or more characters).
+
+However, hold on. `twitter.com` was renamed to `x.com`. You can simply replace `twitter.com` with `x.com` but no one knows when the new owner will change his mind again to roll it back. Therefore, let's target both `twitter.com` and `x.com`.
+
+To do that, switch from Wildcard to [Regular Expression](redirect-rule?id=regular-expression), and set this as the pattern:
+
+```
+https://(twitter|x).com/.*
+```
+
+* `(twitter|x)`: it targets both `twitter` and `x`. (`|` is called *a pipe*.)
+* `.*`: It's the same as Wildcard's `*`. More specifically, `.` means *any character* and `*` means *anything before this symbol repeated any number of times*, resulting in it matches anything.
+
+It's a bit complicated, but once you get used to it, it will be a super powerful tool. We recommend using [RegExr](https://regexr.com) as a playground to analyze how your Regular Expression pattern works.
+
+> [!NOTE]
+> In Regular Expressions, `.` in `(twitter|x).com` is also treated as *any character*. Therefore, `(twitter|x).com/.*` also matches, for example, `twitter1com/` or `x_com/`.
+> 
+> To avoid it, you can change it to `(twitter|x)\.com/.*`. `\` is used to escape a special character.
+>
+> However, there are no such URLs in the general internet environment. Therefore, you can leave `.` as a special character if you prefer. Your rule is for your own use, so implement it as you see fit.
+
+### Step 2: Set up "Redirect To"
+
+Simply specify the URL as follows:
+
+```
+https://insighttimer.com/saraauster/guided-meditations/calm
+```
+
+Now, Redirect Web brings you to the meditation when you access Twitter!
+
+**[⬇️ Download the Rule](assets/reduce-twitter-addiction.redirectweb ':ignore')**
+
+
+## Case 2: Add Query Parameters from URL
+
+Let's say there is a website called `example.com` that shows a mobile layout by default, but you prefer their desktop layout. Fortunately, the website supports a `layout` query parameter to specify which layout the website displays. Let's create a rule that adds `layout=desktop` automatically.
+
+Perhaps you think you could define it as follows:
+
+* **Redirect From**: `https://example.com/.*` (Regular Expression)
+* **Redirect To**: `$0?layout=desktop`
+
+`$0` references the target URL. If you try to access `example.com/hello`, you're redirected to `example.com/hello?layout=desktop`. This feature is called *substitution*.
+
+> [!TIP]
+> Substitution is also available for the Wildcard mode since it's internally converted to Regular Expression.
+
+However, there are a few problems with these settings.
+
+### Problem 1: Infinite loop
+
+The current setting creates an infinite redirect loop since `https://example.com/.*` also targets `https://example.com/hello?layout=desktop`.
+
+In this case, you can specify an excluded URL pattern that allows you to access without redirection, like this with Regular Expression:
+
+```
+.*[&?]layout=[^&]*.*
+```
+
+* `.*`: Matches anything
+* `[&?]`: Matches either `&` or `?`
+* `[^&]`: Matches *any character except `&`
+
+### Problem 2: Target Already Has Existing Parameters
+
+If the target URL already has other query parameters like `example.com/hello?theme=dark`, the destination will be `example.com/hello?theme=dark?layout=desktop`. You can only join the parameters with `&`. `?` is only allowed at the beginning of the parameters. So it's not treated as a valid parameter.
+
+In this case, change the settings like this:
+
+* **Redirect From**: `(https://example.com/[^?]*)(\?(.*))?`
+* **Redirect To**: `$1?layout=desktop&$3`
+
+Let's take a look step by step.
+
+* `(https://example.com/[^?]*)`: Matches the part until the previous character of `?`.
+    * `[^?]` matches *any character except `?`.
+    * This is wrapped with `()` so you can reference it with `$1` later.
+* `(\?(.*))?`: Matches a string start with `?`, which means query parameters.
+    * This also matches empty string by the `?` quantifier at the end of the pattern, which *matches zero or one time*.
+    * The outer `()` and the inner `()` can be referenced with `$2` and `$3` later.
+
+[RegExr](https://regexr.com) may help you understand the details.
+
+> [!NOTE]
+> RegExr shows an error when you don't escape `/` with `\`. Although you can escape it, it's not required since Redirect Web uses a different engine by Apple that doesn't require escaping.
+
+This is not a perfect solution, as it redirects `example.com/hello` to `example.com/hello?layout=desktop&`, which includes an unnecessary `&` at the end of the URL. It's not a big deal in general, but if you wish to remove it, you can use **Capture Group Processing**.
+
+In conclusion, this is the final output:
+
+* **Redirect From**: `(https://example.com/[^?]*)((\?(.*))?)` (Regular Expression)
+* **Redirect To**: `$1?layout=desktop$3`
+* **Excluded URL Pattern**: `.*[&?]layout=[^&]*.*` (Regular Expression)
+* **Capture Group Processing**:
+    * **Group**: `$3`
+    * **Process**: Replace Occurrences
+        * **Target**: `\?(.*)`
+        * **Replacement**: `&$1`
+
+**[⬇️ Download the Rule](assets/add-parameters.redirectweb ':ignore')**
+
+This is merely an example. You can also create multiple rules to handle each problem. It can be much simpler.
+
+
+## Case 3: Remove Query Parameters from URL
+
+This time, let's say you find out a query parameter `source=twitter` that the website uses to track you, and you decide to remove it to anonymize yourself.
+
+The rule would look like this:
+
+* **Redirect From**: `(https://example.com/[^?]*)(.*[&?])(source=[^&]*)(.*)` (Regular Expression)
+* **Redirect To**: `$1$2$4`
+
+**[⬇️ Download the Rule](assets/remove-parameters.redirectweb ':ignore')**
+
+The destination may include unnecessary characters such as `?` at the end, `&&`, and `?&`. Although they don't cause any problems in general, check the rule you can download from the following link if you wish to remove them:
