## Instructions

1. Install [ProofMode](https://proofmode.org) and [Signal](https://www.signal.org) on an Android phone.
- We tested the HTC Exodus 1s, so that's preferred, but you'll need a SIM card to get Signal to work.
- The version we tested is **0.0.15-RC-1** on Google Play (this is the current version you'll find)
- ~~Please use [ProofMode 0.0.15-BETA-3](https://github.com/guardianproject/proofmode/releases/download/0.0.15-BETA-3/ProofMode-0.0.15-BETA-3-artwork-release.apk) instead of the one in Google Play (this contains a fix to a bug that seems to prevent direct sharing from SD card)~~

2. In ProofMode, enable all the features.


3. Load an SD card with professional camera photos into the phone.

4. Select a photo (or photos) from phone's Photo Gallery and share to ProofMode.



5. Press `GENERATE PROOF` then `SHARE ROBUST`. Note that this step should occur close in time and place to where photos are captured.



6. Find the generated ZIP, select Signal and send to Starling Lab's number.

## Batch upload of 16 photos from Canon XSi (76 MB zip)

~~You must use [ProofMode 0.0.15-BETA-3](https://github.com/guardianproject/proofmode/releases/download/0.0.15-BETA-3/ProofMode-0.0.15-BETA-3-artwork-release.apk) instead of the one in Google Play.~~

1. Once you put the microSD into the HTC Exodus 1s, the photos will show up in the Photos app.


2. Select photos and `Share Proof`.


3. Select `Actual size`.


4. Select `SHARE ROBUST`.


5. Share to the Starling number via Signal.


6. Send the ProofMode ZIP. Watch for the 💾 that indicates acceptance.
