 While being simple, Picocrypt also strives to be powerful in the hands of knowledgeable and advanced users. Thus, there are some additional options that you may use to suit your needs.
 <ul>
 	<li><strong>Password generator</strong>: Picocrypt provides a secure password generator that you can use to create cryptographically secure passwords. You can customize the password length, as well as the types of characters to include.</li>
-	<li><strong>Comments</strong>: Use this to store notes, information, and text along with the file (it won't be encrypted). For example, you can put a description of the file you're encrypting before sending it to someone. When the person you sent it to drops the file into Picocrypt, your description will be shown to that person.</li>
+	<li><strong>Comments</strong>: Use this to store notes, information, and text along with the file (<strong>it won't be encrypted</strong>). For example, you can put a description of the file you're encrypting before sending it to someone. When the person you sent it to drops the file into Picocrypt, your description will be shown to that person. <strong>Comments are not authenticated, meaning it can be freely modified by an attacker. Thus, it should only be used for informational purposes in trusted environments.</strong></li>
 	<li><strong>Keyfiles</strong>: Picocrypt supports the use of keyfiles as an additional form of authentication (or the only form of authentication). Any file can be used as a keyfile, and a secure keyfile generator is provided for convenience. Not only can you use multiple keyfiles, but you can also require the correct order of keyfiles to be present for a successful decryption to occur. A particularly good use case of multiple keyfiles is creating a shared volume, where each person holds a keyfile, and all of them (and their keyfiles) must be present to decrypt the shared volume. By checking the "Require correct order" box and dropping your keyfile in last, you can also ensure that you'll always be the one clicking the Decrypt button.</li>
 	<li><strong>Paranoid mode</strong>: Using this mode will encrypt your data with both XChaCha20 and Serpent in a cascade fashion, and use HMAC-SHA3 to authenticate data instead of BLAKE2b. Argon2 parameters will be increased significantly as well. This is recommended for protecting top-secret files and provides the highest level of practical security attainable. For a hacker to break into your encrypted data, both the XChaCha20 cipher and the Serpent cipher must be broken, assuming you've chosen a good password. It's safe to say that in this mode, your files are impossible to crack. Keep in mind, however, that this mode is slower and isn't really necessary unless you're a government agent with classified data or a whistleblower under threat.</li>
 	<li><strong>Reed-Solomon</strong>: This feature is very useful if you are planning to archive important data on a cloud provider or external medium for a long time. If checked, Picocrypt will use the Reed-Solomon error correction code to add 8 extra bytes for every 128 bytes of data to prevent file corruption. This means that up to ~3% of your file can corrupt and Picocrypt will still be able to correct the errors and decrypt your files with no corruption. Of course, if your file corrupts very badly (e.g., you dropped your hard drive), Picocrypt won't be able to fully recover your files, but it will try its best to recover what it can. Note that this option will slow down encryption and decryption speeds significantly.</li>
