Netalertx Plugin Readme

Plugin README Documentation

Structure

• ## Overview — prose: what the plugin does and why, 1-3 sentences. Link out to a full guide under docs/*.md if one exists for this topic.
• ### Requirements / ### Prerequisites (optional) — only when there's a real precondition beyond installing the app (credentials, specific hardware/firmware, host networking, a third-party account).
• ### Usage — how a user actually engages with the plugin: where to enable it, the overall flow, which non-obvious values they need to go find elsewhere (e.g. "grab your API key from your provider's dashboard"). Not a settings reference table.
• ### Notes (optional) — caveats, gotchas, limitations, similar/related plugins worth cross-linking.
• ## Other info (optional) — Version / Author / Maintainer(s) / Release Date. Never drop this when rewriting a README - if it's there, carry it forward verbatim even if you're rewriting everything else.

The core rule: don't re-document settings

Every setting already gets a name and description shown directly in the Settings UI, generated straight from config.json. A README that re-lists each setting with its key and default value duplicates that and drifts out of sync the moment config.json changes — the UI is the single source of truth for field-level docs, not the README.

Exception: call out a specific setting by name, in prose, only when its behavior is genuinely non-obvious - e.g. a setting whose name doesn't match what it actually holds (_publisher_telegram's HOST setting is actually the chat ID, URL is the bot token), a recommended value or schedule, or an upstream bug tied to a specific value (see unifi_import's UNFIMP_version/UNFIMP_port note). Don't turn this into a table of every field "just in case" - if you're listing more than one or two settings, ask whether that content belongs in the UI's per-field description instead.

Verify against the actual code first

Read config.json (unique_prefix, plugin_type, data_source, settings) and the plugin's script before writing anything - don't guess at mechanism from the plugin's name alone. A README copied from a sibling plugin or left as the unedited __template/README.md describes the wrong plugin's behavior.

Backfilling missing "Other info"

Before concluding a plugin has no attribution to record, grep its script for a credit comment (e.g. grep -rn "Based on\|Author:" server/plugins/<code_name>/*.py) - two plugins (dhcp_servers, website_monitor) had # Based on the work of https://github.com/leiweibau/Pi.Alert in the script that nothing in the README reflected. Do not use git log --diff-filter=A "who first added this file" as an attribution source - server/plugins/ has at least one bulk restructuring commit, so several unrelated plugins share the same "first added" date/author despite having nothing to do with each other. If you can't verify authorship from an in-source comment or an existing (already-correct) README, leave the section out rather than guess - most first-party/core plugins (maintenance, custom_props, db_cleanup, set_password, etc.) simply don't have one, which is the correct, honest state.

Cross-linking convention

• Link to a top-level docs page: https://docs.netalertx.com/PAGE_NAME. Never /docs/PAGE_NAME.md or a github.com/.../tree/main/... URL - both break once the README is rendered inside the docs site (docs/gen_plugin_pages.py generates it at a different path than the repo, so repo-relative and GitHub-tree links don't resolve there).
• Link to another plugin's README: https://docs.netalertx.com/plugins/<code_name> (matches the page docs/gen_plugin_pages.py generates for it). Never a GitHub tree URL.
• If a docs/*.md guide is dedicated to (or shared by) this plugin, link both directions - plugin → guide, and guide → plugin. Check the other side actually links back; it's easy to add one direction and forget the other (e.g. PIHOLE_GUIDE.md linked to four Pi-hole plugins, none of which linked back, until this was audited).
• If a sibling plugin is easily confused with this one (unifi_import vs unifi_api_import, dig_scan vs nslookup_scan, adguard_export vs adguard_import), say so in one sentence and link it - which one to prefer and why.

Common defects to check for when auditing existing READMEs

• Template leftovers: grep for Plugin name, <your github handle>, Some tip., PREF_RUN - a sign the README was never actually written. Diff against server/plugins/__template/README.md if unsure.
• Content copy-pasted from a sibling plugin without updating the tool/utility name.
• TBC or similarly empty content, especially for a prominent feature.
• Duplicate or orphaned sections (e.g. two ### Usage headings) - usually a merge/edit artifact.
• Sibling non-README files (a provider-specific sub-guide, a translated README_<LANG>.md) that aren't linked from the plugin's own README.md - docs/gen_plugin_pages.py generates a page for every *.md in the plugin folder, but only reachable if something links to it.

Reference

• Repo-wide plugin catalog with icon/type legend: docs/PLUGINS_OVERVIEW.md
• Full plugin authoring reference (settings schema, execution phases, data contract): docs/PLUGINS_DEV.md and the plugin-run-development skill.
