	### Latest Release

	- **\`ISO\`** : [${RELEASE}](${URL}/${TAG}/${RELEASE})
	- **\`SIG\`** : [${RELEASE}.sig](${URL}/${TAG}/${RELEASE}.sig)
	- **\`SHA\`** : [${RELEASE}.sha256sum](${URL}/${TAG}/${RELEASE}.sha256sum)
	\`${SHA}\`
	- **\`TORRENT\`** : [${RELEASE}.torrent](${URL}/${TAG}/${RELEASE}.torrent)

	### Verify the authenticity of the ISO

	- Download the **\`ISO\`**, **\`gpg signature\`** and **\`sha256sum\`** files
	- Make sure all the files are present in the same directory (Assuming \`~/Downloads\`)
	- First, Verify the details of the key on keyserver, Open a terminal and run (any one):
	\`\`\`
	\$ gpg --keyserver hkps://keys.gnupg.net --recv-keys ${KEY}
	\$ gpg --keyserver hkps://keyserver.ubuntu.com --recv-keys ${KEY}
	\$ gpg --keyserver hkp://pgp.mit.edu --recv-keys ${KEY}
	\`\`\`

	- Then, Open \`terminal\` in the \`~/Downloads\` folder and run following command :
	\`\`\`
	\$ gpg --verify ${RELEASE}.sig
	\`\`\`

	- Finally, Verify the \`sha256sum\` by running :
	\`\`\`
	\$ sha256sum -c ${RELEASE}.sha256sum
	\`\`\`
