+# Echo - Never Miss a Moment
 
-Time travelling recorder for Android.
-It is free/libre and gratis software.
+Echo is a modern Android application that continuously records audio in the background, allowing you to go back in time and save moments that have already happened. Whether it's a brilliant idea, a funny quote, or an important note, Echo ensures you never miss it.
 
-Download
----
+## Features
 
-* [F-Droid](https://f-droid.org/repository/browse/?fdid=eu.mrogalski.saidit)
+*   **Continuous Background Recording:** Echo runs silently in the background, keeping a rolling buffer of the last few hours of audio.
+*   **Save Clips from the Past:** Instantly save audio clips of various lengths from the buffered memory.
+*   **Auto-Save:** Automatically save recordings when the memory buffer is full, ensuring you never lose important audio.
+*   **Modern, Intuitive Interface:** A clean, professional design built with Material You principles.
+*   **Customizable Settings:** Adjust the audio quality and memory usage to fit your needs.
 
-Building
----
+## Getting Started
 
-1. Install gradle-1.10 (version is important)
-1. Install SDK platform API 21 and 21.0.2 build-tools, with either [sdkmanager](https://developer.android.com/studio/command-line/sdkmanager) or [Android Studio](https://developer.android.com/studio)
-1. Create a Key Store - [Instructions](http://stackoverflow.com/questions/3997748/how-can-i-create-a-keystore)
-1. Fill Key Store details in `SaidIt/build.gradle`
-1. From this directory run `gradle installDebug` - to install it on a phone or `gradle assembleRelease` - to generate signed APK
+### Prerequisites
 
-If you had any issues and fixed them, please correct these instructions in your fork!
+*   Android Studio
+*   Java Development Kit (JDK)
+
+### Building the Project
+
+1.  **Clone the repository:**

+    ```
+    sdk.dir=/path/to/your/android/sdk
+    ```
+4.  **Build the project:**
+    *   From the command line, run:
