System requirements

sarchile is now only support aarch64 CPU architecture, arm 32bit is available but it's very experimental and amd64 support is planned.

There is no actual hardware or software minimal requirement to install sarchile. If your phone can install and work with Termux normally then you are pretty fine to go.

However, to ensure the best experience, your device should...

• Have at least 1GB of free storage to successfully install sarchile (roughly 510M after install), but for a more daily usage we suggest 8GB of free storage or higher.
• If you're a developer and plan to use sarchile for software development, 16GB of free storage and 6GB of device RAM or higher should be great.
• sarchile itself uses nearly no memory at idle, but 4GB of device memory is recommended. Because your Android system (and other Android apps) could've take a plenty of memory already.

If you managed to install sarchile on a SD card then it's okay, but it won't last long. You have been warned.
