What should a CLI install page include so users can verify it?

An install page that makes verification easy lists the version, a checksum, a signature command, supported platforms and how to report problems.

An install page that makes verification easy shows the current version, a copyable checksum command with the expected value, how to check a signature if you sign releases, the supported platforms, and where to report a problem. If checking takes more than a minute, most people will skip it.

Why the page matters

Users compare your page to others they have seen. A page that gives only a one-line install command invites a one-line trust decision. A page that also shows how to confirm the file is genuine sets the habit, and gives security reviewers something to point to.

What to put on it

ItemWhy it is there
Current version and release datePeople check they are not installing something stale
Install command per platformOne block each, copy ready
Expected checksum per fileA value to compare against
Verify commandThe exact command to run, for each platform
Signature check, if signedNames the key or identity users should expect
Link to release notesShows what changed
SBOM linkFor customers who track components
Security contactWhere to report a problem

How to write the verify block

  1. Show the download command, then the checksum command, then the expected value on the next line.
  2. Use the tools already on each platform, so users do not install another tool just to check.
  3. Say what a pass looks like and what a failure looks like, in one sentence each.
  4. If you sign, show the exact identity or key fingerprint to expect, so users compare against something fixed.
  5. Put the checksum in a place an attacker would have to compromise separately from the file host, for example the release notes as well as a checksums file.

For the difference between the two methods see checksum or signature, which to trust.

Things that quietly weaken the page

  • Showing only the install command with a checksum hidden in a repository folder.
  • A signature key that is not described anywhere on the page.
  • An old version number left up after a release.
  • Instructions that say to disable a system warning without explaining why.
  • Dead links to release notes.

Keep it current

Add the page to your release checklist. Update the version, checksums and links as part of cutting a release, not afterwards. A script that fills in the values from the build output removes the chance of a typo.

Offer an offline path

Some users install on machines with no direct internet. Publish the files and checksums so they can transfer and verify them by hand. A page that only works with a live pipe to a shell shuts them out.

Quick check

Is a checksum on the download page enough?

It catches corruption. Because an attacker who changes the file may change the page too, add a signature or publish the checksum in a second place.

Should the page show an SBOM link?

It helps customers who track components. Link it beside the release.
