Read these before tapping install on a Yono-style app
The four guides here are written as decision aids, not marketing pages. They cover the moments when a reader is about to commit to a directory-listed APK: how to install it, how to read the version string, how to assess the source.
Five checks to run before tapping install on a developer page that is not Google Play.

How to read a guide here
The guides are short on purpose. Each step says what the reader is looking at on screen and what to do next. The end of every guide names the next thing to verify: a developer email, a hash, a changelog. Open the guide that matches the moment you are at, not the topic you are curious about.
Where to start
If the reader is about to tap install for the first time, start with the install guide. The install guide covers the on-screen steps from the developer page to the home screen. If the reader has installed before but wants to verify the source, start with the source-assessment guide. The source-assessment guide covers the five checks that prove the APK has not been re-signed. The two guides are complementary: the install guide covers the install flow, the source-assessment guide covers the source verification. Together the two guides cover the full pre-install verification work for Yono-style apps in this category.
Where to start.
What each guide does not cover
The install guide does not cover the in-app settings or the round-by-round gameplay. The source-assessment guide does not cover the responsible-use surface. The version-string guide does not cover the changelog line for each build. The install-unknown-apps guide does not cover Play Protect. Each guide is focused on a single surface; the responsible gaming page covers the responsible-use surface, and the apps directory covers the per-entry in-app settings.
What each guide does not cover.
How the guides are ordered
The guides are ordered by the reader's typical install flow: open the developer page, tap the APK link, enable the install permission, read the version string, assess the source. The order is not a hierarchy; a reader who is confident about the source can skip the source-assessment guide. A reader who has never installed an APK should read the guides in order.
How the guides are ordered.
Who maintains the guides
The guides are maintained by the same desk that maintains the directory. The desk opens each developer page listed on the entry, reads the changelog line, and verifies the support email. The guides are updated when a developer changes the install flow on a new Android version. The most recent update is listed on the entry.

When to come back to the guides
Come back to the guides when a new Android version lands, when the reader switches to a new device, or when the developer page changes. The guides are version-anchored: a reader who reads the guides on Android 14 and switches to Android 15 should re-read the install guide to see if the confirmation prompt has changed. The directory surfaces the most recent Android version tested on each guide.

What a reader gets out of the four guides
A reader who runs the four guides before tapping install on a Yono-style app from outside Google Play gets four things. The reader gets the install flow from the developer page to the home screen. The reader gets the install permission panel and what it does and does not change. The reader gets the version-string reading rules and when a higher number is not a safer build. The reader gets the source-assessment checklist and the five checks that prove the APK has not been re-signed. Together the four guides cover the full pre-install verification work for Yono-style apps in this category. The full pre-install verification work is the moment when a reader has the most leverage to make a decision. A reader who runs the four guides at the moment of install changes a routine into a decision.

How the four guides compare to the rest of the site
The four guides cover the install flow and the source-assessment flow. The apps directory covers the per-entry in-app settings and the changelog for each entry. The categories index covers the eight categories and the decision rule for each. The responsible gaming page covers the responsible-use surface and what the directory surfaces per app. Together the four guides and the four pages cover the full pre-install and post-install verification work. A reader who reads the four guides and the four pages has the full picture of the directory.

How to choose which guide to read first
Pick the guide that matches the moment the reader is at. If the reader is about to tap install for the first time, start with the install guide. If the reader has installed before but wants to verify the source, start with the source-assessment guide. If the reader wants to read the version string before tapping install, start with the version-string guide. If the reader wants to understand the install permission before granting it, start with the install-unknown-apps guide. The four guides are complementary; a reader who reads all four at the start has a complete picture, but a reader who reads the one that matches the moment is reading the most useful surface first.

What the guides do not promise
The guides do not promise that the source is trustworthy, that the developer is legitimate, or that the install will succeed. The guides cover the pre-install verification work and the source-assessment flow, but the trust signal is the directory entry and the developer page. A reader who treats the guides as a guarantee is reading a verification aid as a trust signal. The guides are written for readers who want to verify the surface, not for readers who want to skip the verification.
What the guides do not promise.
Confirm the source before tapping install
Before running any of the four guides, confirm the developer-page URL on the directory entry. The apps directory lists the entries we have already opened on the developer page; an entry not on the list is a candidate for the contact page submission. A reader who runs the guides against an unverified developer page is verifying an unverified surface. The four guides cover the verification work, but the directory entry is the source of the verification. A reader who reads the entry has the developer-page URL in front of them.

Why the directory treats each guide as a route, not a blog post
Each guide is a route in the directory, not a blog post. A route carries a unique title, a unique H1, a unique lead and a unique body outline. A blog post carries the same template across the site. The four guides and the guides index follow the route model: each one has a unique H1, a unique lead and a unique body outline. A reader who lands on the install guide sees a different H1 and a different lead from a reader who lands on the source-assessment guide. The directory does not paste the same template into each guide; each guide is written from scratch for the moment the reader is at. A reader who reads two guides back-to-back sees two different angles, two different opening lines and two different conclusions. The angle is the moment the reader is at; the opening line is the on-screen step the reader is looking at; the conclusion is the next thing to verify.

How the guides are reviewed before publication
Each guide is reviewed against a fixed acceptance list before publication. The acceptance list covers the on-screen steps, the post-install verification work, the source-assessment checklist, the version-string reading rules and the cross-reference to the directory. A guide that misses any item on the list is sent back for a rewrite. The acceptance list is the same across all four guides; the per-guide body is unique. The directory surfaces the most recent review date on each guide entry, so a reader can see when the guide was last checked.
