 # Jitsi Meet SDK for Android
 
-## Build
+## Build your own, or use a pre-build SDK artifacts/binaries
+Jitsi conveniently provides a pre-build SDK artifacts/binaries in its Maven repository. When you do not require any modification to the SDK itself, it's suggested to use the pre-build SDK. This avoids the complexity of building and installing your own SDK artifacts/binaries.
+
+### Use pre-build SDK artifacts/binaries
+In your project, add the Maven repository
+`https://github.com/jitsi/jitsi-maven-repository/raw/master/releases` and the
+dependency `org.jitsi.react:jitsi-meet-sdk` into your `build.gradle` files.
+
+The repository typically goes into the `build.gradle` file in the root of your project:
+
+```gradle
+allprojects {
+    repositories {
+        google()
+        jcenter()
+        maven {
+            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
+        }
+    }
+}
+```
+
+Dependency definitions belong in the individual module `build.gradle` files:
+
+```gradle
+dependencies {
+    // (other dependencies)
+    implementation ('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }
+}
+```
+
+### Build and use your own SDK artifacts/binaries
 
 1. Install all required [dependencies](https://github.com/jitsi/jitsi-meet/blob/master/doc/mobile.md).
 
-2. ```bash
+2. Create the SDK-release assembly, by invoking the following in the jitsi-meet
+   project source:
+
+   ```bash
    cd android/
    ./gradlew :sdk:assembleRelease
    ```
+   When this successfully executes, artifacts/binaries are ready to be published
+   into a Maven repository of your choice.
 
 3. Configure the Maven repositories in which you are going to publish the
-   artifacts/binaries during step 4. Modify
+   artifacts/binaries during step 4.
+
+   In the file `android/sdk/build.gradle` modify the line that contains
    `"file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"`
-   in adroid/sdk/build.gradle for Jitsi Meet SDK for Android and/or
-   `"file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"`
-   in android/build.gradle for the third-party react-native modules which Jitsi
-   Meet SDK for Android depends on and are not publicly available in Maven
-   repositories. Generally, if you are modifying the JavaScript code of Jitsi
-   Meet SDK for Android only, you will very likely need to consider the former
-   only.
+
+   Change this value (which represents the Maven repository location used internally
+   by the Jitsi Developers) to the location of the repository that you'd like to use.
 
 4. Publish the Maven artifact/binary of Jitsi Meet SDK for Android in the Maven
    repository configured in step 3:
@@ -27,27 +61,66 @@
    ./gradlew :sdk:publish

    ```
+5. In _your_ project, add the Maven repository that you configured in step 3, as well
+   as the dependency `org.jitsi.react:jitsi-meet-sdk` into your `build.gradle`
+   file. Note that it's needed to pull in the transitive dependencies:
 
-   If you would like to publish a third-party react-native module which Jitsi
-   Meet SDK for Android depends on and is not publicly available in Maven
-   repositories, replace `sdk` with the name of the react-native module. For
-   example, to publish react-native-webrtc:
+   ```gradle
+   implementation ('org.jitsi.react:jitsi-meet-sdk:+') { transitive = true }
+   ```
+
+Generally, if you are modifying the JavaScript code of Jitsi Meet SDK for Android only,
+the above will suffice. If you would like to publish a third-party react-native module
+which Jitsi Meet SDK for Android depends on (and is not publicly available in Maven
+repositories) continue below.
+
+6. Create the release assembly for _each_ third-party react-native module that you
+   need, replacing it's name in the example below.
+
+   ```bash
+   ./gradlew :react-native-webrtc:assembleRelease
+   ```
+
+7. Configure the Maven repositories in which you are going to publish the
+   artifacts/binaries during step 8.
+
+   In the file `android/build.gradle` (note that this is a different file than the file
+   that was modified in step 3) modify the line that contains
+   `"file:${rootProject.projectDir}/../../../jitsi/jitsi-maven-repository/releases"`
+
+   Change this value (which represents the Maven repository location used internally
+   by the Jitsi Developers) to the location of the repository that you'd like to use.
+   You can use the same repository as the one you configured in step 3 if you want.
+
+8. Publish the Maven artifact/binary of _each_ third-party react-native module that
+   you need, replacing it's name in the example below. For example, to publish
+   react-native-webrtc:
 
    ```bash
    ./gradlew :react-native-webrtc:publish
    ```
 
-## Install
+   Note that there should not be a need to explicitly add these dependencies in
+   _your_ project, as they will be pulled in as transitive dependencies of
+   `jitsi-meet-sdk`.
 
-Add the Maven repository
-`https://github.com/jitsi/jitsi-maven-repository/raw/master/releases` and the

 One-to-one calls should avoid going throught the JVB for optimal performance and for optimal resource usage. This is why we've added the peer-to-peer mode where the two participants connect directly to each other. Unfortunately, a direct connection is not always possible between the participants. In those cases you can use a TURN server to relay the traffic (n.b. the JVB does much more than just relay the traffic, so this is not the same as using the JVB to "relay" the traffic).
