 ### Encryption
 This program relies on only one database file, encrypted with [XChaCha20Poly1305](https://doc.libsodium.org/advanced/stream_ciphers/xchacha20) authenticated encryption and [Argon2id](https://en.wikipedia.org/wiki/Argon2) for key derivation.
 ### Import/Export
-You can import backups made by [Aegis](https://github.com/beemdevelopment/Aegis) and [andOTP](https://github.com/andOTP/andOTP) Authenticators, but backup compatibility is growing (check [planned features](#planned-features)).

+Backup compatibility is growing (check [planned features](#planned-features)).
 By typing `cotp -ex` you can export your database in unencrypted json format.
 ### Compatibility
 cotp can generate two-factor authentication coded using HMAC-SHA1, HMAC-SHA256 and HMAC-SHA512, with any digits, to provide a good compatibility to most two-factor authentication systems.

+## Database conversion
+To import Authy or Google Authenticator databases you need first of all to obtain the respective files in your phone in the paths: 
+- **Authy**: `/data/data/com.authy.authy/shared_prefs/com.authy.storage.tokens.authenticator.xml`
+- **Google Authenticator**: `/data/data/com.google.android.apps.authenticator2/databases/databases`
+
+After that run the correct python script located in the converters/ folder in this source code:
+
+`python authy.py path/to/database.xml converted.json`
+
+It will convert the database in a json format readable by cotp.

+To finish import the database: `cotp -i authy path/to/database.json`
