+This solution may be of particular use if you already use the [steamguard-cli](https://github.com/dyc3/steamguard-cli) your PC. It avoids the need for a rooted Android device to extract secrets from.
+
+1. First off you need to open your steamguard-cli file directory (usually `~/.config/steamguard-cli/maFiles/`), and find the *.maFile inside. 
+
+2. Then you can either open it with your favourite text editor and copy yourTOTPSecret in `uri` field (looks like `otpauth://totp/Steam:{yourUserName}?secret{yourTOTPSecret}&issuer=Steam`) and send it to your phone, or send the file to your phone first than copy yourTOTPSecret afterwords.
+
+*Alternatively, you could copy the whole `uri` field and generate a qr code locally, for example on linux by running `qr "otpauth://totp/Steam:{yourUserName}?secret{yourTOTPSecret}&issuer=Steam"`, scanning the qr code on Aegis, pressing advanced, setting the type to steam and pressing save.*
+
+DO **NOT** USE AN ONLINE QR CODE GENERATOR, IF YOU DO THEY WOULD HAVE ACCESS TO YOUR STEAM 2FA CODE
+
+3. Open Aegis and press the '+' button and select enter manually
+
+4. Paste yourTOTPSecret into the secret field, press advanced, press type and select steam
+
+5. Fill out the rest of the non-advanced fields as you wish, and press save when you are finished
+
+You should now have your steam code inside Aegis as well!
