 As a codebase increases in size and complexity, static analysis checks become a very useful tool in ensuring high quality, bug free code. This repository provides a collection of lint checks based on Android Lint that guard against common pitfalls and bugs that you might encounter in day to day development.

+# Getting Started
+
+To add lint-checks to your project, simply add the relevant artifact in your app/module's `build.gradle` file.
+```groovy
+dependencies {
+  lintChecks "com.uber.lint-checks:lint-checks:x.y.z
+}
+```
+
+## Lint Modules
+
+Here's a list of lint modules that this project provides:
+
+#### Java/Kotlin Lint Checks
+```groovy
+lintChecks "com.uber.lint-checks:lint-checks:x.y.z
+```
+#### Android Lint Checks
+```groovy
+lintChecks "com.uber.lint-checks:lint-checks-android:x.y.z
+```
+#### RxJava Lint Checks
+```groovy
+lintChecks "com.uber.lint-checks:lint-checks-rxjava:x.y.z
+```
+The list of individual lint checks in each module can be found [here](https://uber.github.io/lint-checks/CHECKS/)
+
+## Integrating In An Existing Codebase
+
+Integrating new tooling into an existing codebase can be a pain. Luckily, Android Lint makes it easy to start using lint by providing a [baseline](https://developer.android.com/studio/write/lint#snapshot). A baseline lets you take a snapshot of your project and then uses the snapshot as a baseline for future inspection runs. 
+
+To create a baseline add the following in your `build.gradle` file.
+```groovy
+android {
+  lintOptions {
+    baseline file("lint-baseline.xml")
+  }
+}
+```
+More info on baselines can be found in the [official documentation](https://developer.android.com/studio/write/lint#snapshot)
+
+## Enabling/Disabling Lint Checks
+
+There are cases when a particular lint check is not applicable to your codebase or when you want to _enable_ a lint check that's disabled by default. 
+
+You can use Android Lint's `lintOptions` to customize your own setup. 
+
+```groovy
+android {
+  lintOptions {
+    // Turns off checks for the issue IDs you specify.
+    disable 'RxJavaDistinct'
+    // Turns on checks for the issue IDs you specify. These checks are in
+    // addition to the default lint checks.
+    enable 'FrameworkPair'
+  }
+}
+```
+
+For more info on lintOptions, take a look at the [official documentation](https://developer.android.com/studio/write/lint)
