+# 💉 Introduction to ReVanced Patcher
+
+To create patches for Android apps, it is recommended to know the basic concept of ReVanced Patcher.
+
+## 📙 How it works
+
+ReVanced Patcher is a library that allows modifying Android apps by applying patches.
+It is built on top of [Smali](https://github.com/google/smali) for bytecode manipulation and [Androlib (Apktool)](https://github.com/iBotPeaches/Apktool)
+for resource decoding and encoding.
+
+ReVanced Patcher receives a list of patches and applies them to a given APK file.
+It then returns the modified components of the APK file, such as modified dex files and resources,
+that can be repackaged into a new APK file.
+
+ReVanced Patcher has a simple API that allows you to load patches from RVP (JAR or DEX container) files
+and apply them to an APK file. Later on, you will learn how to create patches.
+
+```kt
+val patches = loadPatchesFromJar(setOf(File("revanced-patches.rvp")))
+
+val patcherResult = Patcher(PatcherConfig(apkFile = File("some.apk"))).use { patcher ->
+    // Here you can access metadata about the APK file through patcher.context.packageMetadata
+    // such as package name, version code, version name, etc.
+
+    // Add patches.
+    patcher += patches
+
+    // Execute the patches.
+    runBlocking {
+        patcher().collect { patchResult ->
+            if (patchResult.exception != null)
+                logger.info { "\"${patchResult.patch}\" failed:\n${patchResult.exception}" }
+            else
+                logger.info { "\"${patchResult.patch}\" succeeded" }
+        }
+    }
+
+    // Compile and save the patched APK file components.
+    patcher.get()
+}
+
+// The result of the patcher contains the modified components of the APK file that can be repackaged into a new APK file.
+val dexFiles = patcherResult.dexFiles
+val resources = patcherResult.resources
+```
+
+## ⏭️ What's next
+
+The next page teaches the fundamentals of ReVanced Patches.

+# 👶 Setting up a development environment
+
+To start developing patches with ReVanced Patcher, you must prepare a development environment.
+
+## 📝 Prerequisites
+
+- A Java IDE with Kotlin support, such as [IntelliJ IDEA](https://www.jetbrains.com/idea/)
+- Knowledge of Java, [Kotlin](https://kotlinlang.org), and [Dalvik bytecode](https://source.android.com/docs/core/runtime/dalvik-bytecode)
+- Android reverse engineering skills and tools such as [jadx](https://github.com/skylot/jadx)
+
+## 🏃 Prepare the environment
+
+Throughout the documentation, [ReVanced Patches](https://github.com/revanced/revanced-patches) will be used as an example project.
+
+> [!NOTE]
+> To start a fresh project, 
+> you can use the [ReVanced Patches template](https://github.com/revanced/revanced-patches-template).
+
+1. Clone the repository
+
+   ```bash
+   git clone https://github.com/revanced/revanced-patches && cd revanced-patches
+   ```
+
+2. Build the project
+
+   ```bash
+   ./gradlew build
+   ```
+
+> [!NOTE]
+> If the build fails due to authentication, you may need to authenticate to GitHub Packages.
+> Create a PAT with the scope `read:packages` [here](https://github.com/settings/tokens/new?scopes=read:packages&description=ReVanced) and add your token to ~/.gradle/gradle.properties.
+>
+> Example `gradle.properties` file:
+>
+> ```properties
+> gpr.user = user
+> gpr.key = key
+> ```
+
+3. Open the project in your IDE
+
+> [!TIP]
+> It is a good idea to set up a complete development environment for ReVanced, so that you can also test your patches
+> by following the [ReVanced documentation](https://github.com/ReVanced/revanced-documentation).

+# 🔎 Fingerprinting
+
+In the context of ReVanced, a fingerprint is a partial description of a method.
+It is used to uniquely match a method by its characteristics.
+Fingerprinting is used to match methods with a limited amount of known information.
+Methods with obfuscated names that change with each update are primary candidates for fingerprinting.
+The goal of fingerprinting is to uniquely identify a method by capturing various attributes, such as the return type,
+access flags, an opcode pattern, strings, and more.
+
+## ⛳️ Example fingerprint
+
+An example fingerprint is shown below:
+
+```kt
+
+package app.revanced.patches.ads.fingerprints
+
+fingerprint {
+    accessFlags(AccessFlags.PUBLIC, AccessFlags.FINAL)
+    returns("Z")
+    parameters("Z")
+    opcodes(Opcode.RETURN)
+    strings("pro")
+    custom { (method, classDef) -> classDef == "Lcom/some/app/ads/AdsLoader;" }
+}
+```
+
+## 🔎 Reconstructing the original code from the example fingerprint from above
+
+The following code is reconstructed from the fingerprint to understand how a fingerprint is created.
+
+The fingerprint contains the following information:
+
+- Method signature:
+
+  ```kt
+  accessFlags(AccessFlags.PUBLIC, AccessFlags.FINAL)
+  returns("Z")
+  parameters("Z")
+  ```
+
+- Method implementation:
+
+  ```kt
+  opcodes(Opcode.RETURN)
+  strings("pro")
+  ```
+
+- Package and class name:
+
+  ```kt
+  custom { (method, classDef) -> classDef == "Lcom/some/app/ads/AdsLoader;" }
+  ```
+
+With this information, the original code can be reconstructed:
+
+```java
+package com.some.app.ads;
+
+<accessFlags>
+
+class AdsLoader {
+    public final boolean <methodName>(boolean <parameter>)
+
+    {
+        // ...
+
+        var userStatus = "pro";
+
+        // ...
+
+        return <returnValue >;
+    }
+}
+```
+
+Using that fingerprint, this method can be matched uniquely from all other methods.
+
+> [!TIP]
+> A fingerprint should contain information about a method likely to remain the same across updates.
+> A method's name is not included in the fingerprint because it will likely change with each update in an obfuscated
+> app.
+> In contrast, the return type, access flags, parameters, patterns of opcodes, and strings are likely to remain the
+> same.
+
+## 🔨 How to use fingerprints
+
+After declaring a fingerprint, it can be used in a patch to find the method it matches to:
+
+```kt
+val fingerprint = fingerprint {
+    // ...
+}
+
+val patch = bytecodePatch {
+    execute {
+        fingerprint.method
+    }
+}
+```
+
+The fingerprint won't be matched again, if it has already been matched once, for performance reasons.
+This makes it useful, to share fingerprints between multiple patches,
+and let the first executing patch match the fingerprint:
+
+```kt
+// Either of these two patches will match the fingerprint first and the other patch can reuse the match:
+val mainActivityPatch1 = bytecodePatch {
+    execute {
+        mainActivityOnCreateFingerprint.method
+    }
+}
+
+val mainActivityPatch2 = bytecodePatch {
+    execute {
+        mainActivityOnCreateFingerprint.method
+    }
+}
+```
+
+> [!WARNING]
+> If the fingerprint can not be matched to any method,
+> accessing certain properties of the fingerprint will raise an exception.
+> Instead, the `orNull` properties can be used to return `null` if no match is found.
+
+> [!TIP]
+> If a fingerprint has an opcode pattern, you can use the `fuzzyPatternScanThreshhold` parameter of the `opcode`
+> function to fuzzy match the pattern.  
+> `null` can be used as a wildcard to match any opcode:
+>
+> ```kt
+> fingerprint(fuzzyPatternScanThreshhold = 2) {
+>   opcodes(
+>     Opcode.ICONST_0,
+>     null,
+>     Opcode.ICONST_1,
+>     Opcode.IRETURN,
+>    )
+>}
+> ```
+
+The following properties can be accessed in a fingerprint:
+
+- `originalClassDef`: The original class definition the fingerprint matches to.
+- `originalClassDefOrNull`: The original class definition the fingerprint matches to.
+- `originalMethod`: The original method the fingerprint matches to.
+- `originalMethodOrNull`: The original method the fingerprint matches to.
+- `classDef`: The class the fingerprint matches to.
+- `classDefOrNull`: The class the fingerprint matches to.
+- `method`: The method the fingerprint matches to. If no match is found, an exception is raised.
+- `methodOrNull`: The method the fingerprint matches to.
+
+The difference between the `original` and non-`original` properties is that the `original` properties return the
+original class or method definition, while the non-`original` properties return a mutable copy of the class or method.
+The mutable copies can be modified. They are lazy properties, so they are only computed
+and only then will effectively replace the `original` method or class definition when accessed.
+
+> [!TIP]
+> If only read-only access to the class or method is needed,
+> the `originalClassDef` and `originalMethod` properties should be used,
+> to avoid making a mutable copy of the class or method.
+
+## 🏹 Manually matching fingerprints
+
+By default, a fingerprint is matched automatically against all classes
+when one of the fingerprint's properties is accessed.
+
+Instead, the fingerprint can be matched manually using various overloads of a fingerprint's `match` function:
+
+- In a **list of classes**, if the fingerprint can match in a known subset of classes
+
+  If you have a known list of classes you know the fingerprint can match in,
+  you can match the fingerprint on the list of classes:
+
+  ```kt
+  execute {
+    val match = showAdsFingerprint(classes)
+  }
+  ```
+
+- In a **single class**, if the fingerprint can match in a single known class
+
+  If you know the fingerprint can match a method in a specific class, you can match the fingerprint in the class:
+
+  ```kt
+  execute {
+    val adsLoaderClass = classes.single { it.name == "Lcom/some/app/ads/Loader;" }
+
+    val match = showAdsFingerprint.match(adsLoaderClass)
+  }
+  ```
+
+  Another common usecase is to use a fingerprint to reduce the search space of a method to a single class.
+
+  ```kt
+  execute {
+    // Match showAdsFingerprint in the class of the ads loader found by adsLoaderClassFingerprint.
+    val match = showAdsFingerprint.match(adsLoaderClassFingerprint.classDef)
+  }
+  ```
+
+- Match a **single method**, to extract certain information about it
+
+  The match of a fingerprint contains useful information about the method,
+  such as the start and end index of an opcode pattern or the indices of the instructions with certain string
+  references.
+  A fingerprint can be leveraged to extract such information from a method instead of manually figuring it out:
+
+  ```kt
+  execute {
+    val currentPlanFingerprint = fingerprint {
+      strings("free", "trial")
+    }
+
+    currentPlanFingerprint.match(adsFingerprint.method).let { match ->
+      match.stringMatches.forEach { match ->
+        println("The index of the string '${match.string}' is ${match.index}")
+      }
+    }
+  }
+  ```
+
+> [!WARNING]
+> If the fingerprint can not be matched to any method, calling `match` will raise an
+> exception.
+> Instead, the `orNull` overloads can be used to return `null` if no match is found.

+## 🧩 Patch API
+
+### ⚙️ Patch options
+
+Patches can have options to get and set before a patch is executed.
+Options are useful for making patches configurable.
+After loading the patches using `PatchLoader`, options can be set for a patch.
+Multiple types are already built into ReVanced Patcher and are supported by any application that uses ReVanced Patcher.
+
+To define an option, use the available `option` functions:
+
+```kt
+val patch = bytecodePatch(name = "Patch") {
+    // Add an inbuilt option and delegate it to a property.
+    val value by stringOption(name = "Inbuilt option")
+
+    // Add an option with a custom type and delegate it to a property.
+    val string by option<String>(name = "String option")
+
+    execute {
+        println(value)
+        println(string)
+    }
+}
+```
+
+Options of a patch can be set after loading the patches with `PatchLoader` by obtaining the instance for the patch:
+
+```kt
+loadPatchesJar(patches).apply {
+    // Type is checked at runtime.
+    first { it.name == "Patch" }.options["Option"] = "Value"
+}
+```
+
+The type of an option can be obtained from the `type` property of the option:
+
+```kt
+option.type // The KType of the option. Captures the full type information of the option.
+```
+
+Options can be declared outside a patch and added to a patch manually:
+
+```kt
+val option = stringOption(name = "Option")
+
+bytecodePatch(name = "Patch") {
+    val value by option()
+}
+```
+
+This is useful when the same option is referenced in multiple patches.
+
+### 🧩 Extensions
+
+An extension is a precompiled DEX file merged into the patched app before a patch is executed.
+While patches are compile-time constructs, extensions are runtime constructs
+that extend the patched app with additional classes.
+
+Assume you want to add a complex feature to an app that would need multiple classes and methods:
+
+```java
+public class ComplexPatch {
+    public static void doSomething() {
+        // ...
+    }
+}
+```
+
+After compiling the above code as a DEX file, you can add the DEX file as a resource in the patches file
+and use it in a patch:
+
+```kt
+val patch = bytecodePatch(name = "Complex patch") {
+    extendWith("complex-patch.rve")
+
+    execute {
+        fingerprint.method.addInstructions(0, "invoke-static { }, LComplexPatch;->doSomething()V")
+    }
+}
+```
+
+ReVanced Patcher merges the classes from the extension into `context.classes` before executing the patch.
+When the patch is executed, it can reference the classes and methods from the extension.
+
+> [!NOTE]
+>
+> The [ReVanced Patches template](https://github.com/ReVanced/revanced-patches-template) repository
+> is a template project to create patches and extensions.
+
+> [!TIP]

+> check out the repository for [ReVanced Patches](https://github.com/revanced/revanced-patches).
+
+### ♻️ Finalization
+
+Patches can have a finalization block called after all patches have been executed, in reverse order of patch execution.
+The finalization block is called after all patches that depend on the patch have been executed.
+This is useful for doing post-processing tasks.
+A simple real-world example would be a patch that opens a resource file of the app for writing.
+Other patches that depend on this patch can write to the file, and the finalization block can close the file.
+
+```kt
+val patch = bytecodePatch(name = "Patch") {
+    dependsOn(
+        bytecodePatch(name = "Dependency") {
+            execute {
+                print("1")
+            }
+
+            finalize {
+                print("4")
+            }
+        }
+    )
+
+    execute {
+        print("2")
+    }
+
+    finalize {
+        print("3")
+    }
+}
+```
+
+Because `Patch` depends on `Dependency`, first `Dependency` is executed, then `Patch`.
+Finalization blocks are called in reverse order of patch execution, which means,
+first, the finalization block of `Patch`, then the finalization block of `Dependency` is called.
+The output after executing the patch above would be `1234`.
+The same order is followed for multiple patches depending on the patch.
+
+## 💡 Additional tips
+
+- When using `PatchLoader` to load patches, only patches with a name are loaded.
+  Refer to the inline documentation of `PatchLoader` for detailed information.
+- Patches can depend on others. Dependencies are executed first.
+  The dependent patch will not be executed if a dependency raises an exception while executing.
+- A patch can declare compatibility with specific packages and versions,
+  but patches can still be executed on any package or version.
+  It is recommended that compatibility is specified to present known compatible packages and versions.
+    - If `compatibleWith` is not used, the patch is treated as compatible with any package
+- If a package is specified with no versions, the patch is compatible with any version of the package
+- If an empty array of versions is specified, the patch is not compatible with any version of the package.
+  This is useful for declaring incompatibility with a specific package.
+- A patch can raise a `PatchException` at any time of execution to indicate that the patch failed to execute.

+# 🧩 Introduction to ReVanced Patches
+
+Learn the basic concepts of ReVanced Patcher and how to create patches.
+
+## 📙 Fundamentals
+
+A patch is a piece of code that modifies an Android application.  
+There are multiple types of patches. Each type can modify a different part of the APK, such as the Dalvik VM bytecode, 
+the APK resources, or arbitrary files in the APK:
+
+- A `BytecodePatch` modifies the Dalvik VM bytecode
+- A `ResourcePatch` modifies (decoded) resources
+- A `RawResourcePatch` modifies arbitrary files
+
+Each patch can declare a set of dependencies on other patches. ReVanced Patcher will first execute dependencies
+before executing the patch itself. This way, multiple patches can work together for abstract purposes in a modular way.
+
+The `execute` function is the entry point for a patch. It is called by ReVanced Patcher when the patch is executed.
+The `execute` function receives an instance of a context object that provides access to the APK.
+The patch can use this context to modify the APK.
+
+Each type of context provides different APIs to modify the APK. For example, the `BytecodePatchContext` provides APIs
+to modify the Dalvik VM bytecode, while the `ResourcePatchContext` provides APIs to modify resources.
+
+The difference between `ResourcePatch` and `RawResourcePatch` is that ReVanced Patcher will decode the resources
+if it is supplied a `ResourcePatch` for execution or if any patch depends on a `ResourcePatch`
+and will not decode the resources before executing `RawResourcePatch`.
+Both, `ResourcePatch` and `RawResourcePatch` can modify arbitrary files in the APK,
+whereas only `ResourcePatch` can modify decoded resources. The choice of which type to use depends on the use case.
+Decoding and building resources is a time- and resource-consuming,
+so if the patch does not need to modify decoded resources, it is better to use `RawResourcePatch` or `BytecodePatch`.
+
+Example of patches:
+
+```kt
+@Surpress("unused")
+val bytecodePatch = bytecodePatch {
+    execute { 
+        // More about this on the next page of the documentation.
+    }
+}
+
+@Surpress("unused")
+val rawResourcePatch = rawResourcePatch {
+    execute {
+        // More about this on the next page of the documentation.
+    }
+}
+
+@Surpress("unused")
+val resourcePatch = resourcePatch {
+    execute {
+        // More about this on the next page of the documentation.
+    }
+}
+```

+# 📜 Project structure and conventions
+
+Over time, a specific project structure and conventions have been established.
+
+## 📁 File structure
+
+Patches are organized in a specific way. The file structure looks as follows:
+
+```text
+📦your.patches.app.category
+ ├ 🔍Fingerprints.kt
+ └ 🧩SomePatch.kt
+```
+
+> [!NOTE]
+> Moving fingerprints to a separate file isn't strictly necessary, but it helps the organization when a patch uses multiple fingerprints.
+
+## 📙 Conventions
+
+- 🔥 Name a patch after what it does. For example, if a patch removes ads, name it `Remove ads`.
+  If a patch changes the color of a button, name it `Change button color`
+- 🔥 Write the patch description in the third person, present tense, and end it with a period.
+  If a patch removes ads, the description can be omitted because of redundancy,
+  but if a patch changes the color of a button, the description can be _Changes the color of the resume button to red._
+- 🔥 Write patches with modularity and reusability in mind. Patches can depend on each other,
+  so it is important to write patches in a way that can be used in different contexts.
+- 🔥🔥 Keep patches as minimal as possible. This reduces the risk of failing patches.
+  Instead of involving many abstract changes in one patch or writing entire methods or classes in a patch,
+  you can write code in extensions. An extension is a precompiled DEX file that is merged into the patched app 
+  before this patch is executed.
+  Patches can then reference methods and classes from extensions.
+  A real-world example of extensions can be found in the [ReVanced Patches](https://github.com/ReVanced/revanced-patches) repository
+- 🔥🔥🔥 Do not overload a fingerprint with information about a method that's likely to change.
+  In the example of an obfuscated method, it's better to fingerprint the method by its return type
+  and parameters rather than its name because the name is likely to change. An intelligent selection
+  of an opcode pattern or strings in a method can result in a strong fingerprint dynamic to app updates.
+- 🔥🔥🔥 Document your patches. Patches are abstract, so it is important to document parts of the code
+  that are not self-explanatory. For example, explain why and how a certain method is patched or large blocks
+  of instructions that are modified or added to a method
+

+# 💪 Advanced APIs
+
+A handful of APIs are available to make patch development easier and more efficient.
+
+## 📙 Overview
+
+1. 👹 Create mutable replacements of classes with `proxy(ClassDef)`
+2. 🔍 Find and create mutable replaces with `classBy(Predicate)`
+3. 🏃‍ Navigate method calls recursively by index with `navigate(Method)`
+4. 💾 Read and write resource files with `get(String, Boolean)` and `delete(String)`
+5. 📃 Read and write DOM files using `document(String)` and  `document(InputStream)`
+
+### 🧰 APIs
+
+#### 👹 `proxy(ClassDef)`
+
+By default, the classes are immutable, meaning they cannot be modified.
+To make a class mutable, use the `proxy(ClassDef)` function.
+This function creates a lazy mutable copy of the class definition.
+Accessing the property will replace the original class definition with the mutable copy,
+thus allowing you to make changes to the class. Subsequent accesses will return the same mutable copy.
+
+```kt
+execute {
+    val mutableClass = proxy(classDef)
+    mutableClass.methods.add(Method())
+}
+```
+
+#### 🔍 `classBy(Predicate)`
+
+The `classBy(Predicate)` function is an alternative to finding and creating mutable classes by a predicate.
+It automatically proxies the class definition, making it mutable.
+
+```kt
+execute {
+    // Alternative to proxy(classes.find { it.name == "Lcom/example/MyClass;" })?.classDef
+    val classDef = classBy { it.name == "Lcom/example/MyClass;" }?.classDef
+}
+```
+
+#### 🏃‍ `navigate(Method).at(index)`
+
+The `navigate(Method)` function allows you to navigate method calls recursively by index.
+
+```kt
+execute {
+    // Sequentially navigate to the instructions at index 1 within 'someMethod'.
+    val method = navigate(someMethod).to(1).original() // original() returns the original immutable method.
+    
+    // Further navigate to the second occurrence where the instruction's opcode is 'INVOKEVIRTUAL'.
+    // stop() returns the mutable copy of the method.
+    val method = navigate(someMethod).to(2) { instruction -> instruction.opcode == Opcode.INVOKEVIRTUAL }.stop()
+    
+    // Alternatively, to stop(), you can delegate the method to a variable.
+    val method by navigate(someMethod).to(1)
+    
+    // You can chain multiple calls to at() to navigate deeper into the method.
+    val method by navigate(someMethod).to(1).to(2, 3, 4).to(5)
+}
+```
+
+#### 💾 `get(String, Boolean)` and `delete(String)`
+
+The `get(String, Boolean)` function returns a `File` object that can be used to read and write resource files.
+
+```kt
+execute {
+    val file = get("res/values/strings.xml")
+    val content = file.readText()
+    file.writeText(content)
+}
+```
+
+The `delete` function can mark files for deletion when the APK is rebuilt.
+
+```kt
+execute {
+    delete("res/values/strings.xml")
+}
+```
+
+#### 📃 `document(String)`  and  `document(InputStream)`
+
+The `document` function is used to read and write DOM files.
+
+```kt
+execute {
+    document("res/values/strings.xml").use { document ->
+        val element = doc.createElement("string").apply {
+            textContent = "Hello, World!"
+        }
+        document.documentElement.appendChild(element)
+    }
+}
+```
+
+You can also read documents from an `InputStream`:
+
+```kt
+execute {
+    val inputStream = classLoader.getResourceAsStream("some.xml")
+    document(inputStream).use { document ->
+        // ...
+    }
+}
+```
