-# Guidelines
+This repository contains the primary and community-submitted packages for
+[webinstall.dev](https://webinstall.dev).
 
-- Should install to `./local/opt/<package>-<version>`
+# Installer Guidelines
+
+- Should install to `$HOME/.local/opt/<package>-<version>` or `$HOME/.local/bin`
 - Should not need `sudo` (except perhaps for a one-time `setcap`, etc)
-- Follow the example of
-  <https://github.com/webinstall/packages/tree/master/ripgrep>,
-  <https://github.com/webinstall/packages/tree/master/node>, or
-  <https://github.com/webinstall/packages/tree/master/golang>

+# How it works
+
+- Contacts official release APIs for download URLs
+- Selects the appropriate package version and archive format
+- Installs to `$HOME/.local/`
+- Updates `PATH` via `$HOME/.config/envman/PATH.env`
+- Symlinks or copies current selected version
+
+More technically:
+
+1. `<package>/releases.js` transforms the package's release API into a common formatt
+    - (i.e. HTML, CSV, TAB, or JSON into a specific JSON format)
+    - common release APIs are in `_common/` (i.e. `_common/github.js`)
+2. `_webi/bootstrap.sh` is a template that exchanges system information for a correct installer
+    - contructs a user agent with os, cpu, and utility info (i.e. `macos`, `amd64`, can unpack `tar,zip,xz`)
+3. `_webi/template.sh` is the base installer template with common functions for
+    - checking versions
+    - downloading & unpacking
+    - updating PATH
+    - (re-)linking directories
+4. `<package>/install.sh` may provide functions to override `_webi/template.sh`
+5. Recap:
+    - `curl https://webinstall.dev/<pkg>` => `bootstrap-<pkg>.sh`
+    - `bash bootstrap-<pkg>.sh` => `https://webinstall.dev/api/installers/<pkg>@<ver>.sh?formats=zip,tar`
+    - `bash install-<pkg>.sh` => download, unpack, move, link, update PATH
