+### Checksum Verification
+
+In order to verify that the downloaded file can be trusted checksums are provided in [`checksums.txt`][checksums]. See below for examples of how to use this file.
+
+<details>
+<summary>Successful Verification</summary>
+
+To verify the integrity of the binaries on macOS run the following command in the same directory as the downloaded file:
+
+```sh
+$ shasum -c checksums.txt --ignore-missing
+gen3-client-macos.pkg: OK
+```
+
+If the `shasum` command outputs `OK` than the verification was successful and the executable can be trusted.
+
+</details>
+
+<details>
+<summary>Unsuccessful Verification</summary>
+
+Alternatively if the command outputs `FAILED` than the checksum did not match and the binary should not be run.
+
+```sh
+$ shasum -c checksums.txt --ignore-missing
+shasum: WARNING: 1 computed checksum did NOT match
+shasum: checksums.txt: no file was verified
+```
+
+In such a case please reach out to the ACED development team for assistance.
