+# Amazon KDP — Ready-to-Upload Package & Checklist
+
+*Asterisk Guide*, Second Edition (Asterisk 22 LTS) — Flavio E. Gonçalves
+
+This is the exact package to paste into Amazon KDP. KDP has **no publishing API**, so the
+steps in Part 2 must be done by hand in the KDP dashboard. Everything you need to paste is
+in Part 1. The machine-readable copy of this metadata lives in
+[`book/kdp/listing-metadata.yaml`](listing-metadata.yaml).
+
+---
+
+## Part 1 — The metadata to paste
+
+### Title / author
+- **Title:** Asterisk Guide
+- **Subtitle:** Building an IP PBX with Asterisk 22 LTS
+- **Edition:** Second Edition
+- **Author:** Flavio E. Gonçalves
+- **Language:** English
+
+### Prices (decided)
+- **Paperback list price: $49.99 USD**
+- **Kindle eBook list price: $9.99 USD**
+
+### ISBN
+- **Use the FREE KDP-assigned ISBN** (no purchase needed) for the paperback. The Kindle
+  eBook does not need an ISBN — Amazon uses an ASIN. Do **not** reuse the first-edition
+  ISBN `9781796396973`.
+
+### Paperback specs (must match the interior PDF)
+- **Trim size:** 7.5 x 9.25 in
+- **Paper:** White
+- **Interior:** Black & white
+- **Bleed:** No bleed (interior). The cover is a separate wraparound file with 0.125 in bleed.
+
+### BISAC categories (pick these two; KDP allows up to three)
+1. **COM043000** — COMPUTERS / Networking / General
+2. **COM046000** — COMPUTERS / Operating Systems / Linux
+
+### Keywords (7 boxes)
+1. Asterisk 22
+2. PJSIP
+3. VoIP PBX
+4. SIP trunking
+5. IP telephony
+6. WebRTC Asterisk
+7. open source telephony
+
+### Book description (paste into the Description box)
+
+> The only Asterisk book written for the Asterisk you actually run today. Every other
+> guide on the shelf teaches chan_sip — a module that no longer exists. This second
+> edition is rebuilt from the ground up for Asterisk 22 LTS, where PJSIP is the one and
+> only SIP channel, and every configuration and command in the book was verified against
+> a reproducible Asterisk 22 Docker lab. If an example is in here, it ran.
+>
+> Starting from a clean Linux box, you will install Asterisk, build a working PJSIP PBX,
+> and grow it into a real system: SIP and PJSIP internals, WebRTC browser phones over
+> WSS/DTLS-SRTP, SIP trunking with DIDs and the PSTN, a complete dialplan, queues and
+> call-center features, voicemail, conferencing with ConfBridge, CDR/CEL accounting,
+> AMI/AGI/ARI integration, PJSIP Realtime, hardening against toll fraud, and deployment,
+> monitoring and scaling for production.
+>
+> Written by Flavio E. Gonçalves — Asterisk dCAP, CEO of SipPulse, and author of several
+> telephony titles — with end-of-chapter quizzes and a companion hands-on course and labs
+> at VoIP School Blackbelt. Whether you are new to Asterisk or migrating an aging
+> chan_sip system to PJSIP, this is the current, lab-proven reference for Asterisk 22.
+
+### Author bio (paste into the Author/Contributor bio box)
+
+> Flavio E. Gonçalves is the CEO of SipPulse in Brazil, a company dedicated to
+> softswitches, session border controllers, and multitenant PBXs. He holds the Asterisk
+> dCAP certification (passed on the first attempt) along with a long list of others over
+> his career — Novell MCNE/MCNI, Microsoft MCSE/MCT, and Cisco CCSP/CCNP/CCDP — and has
+> drawn on more than 25 years of teaching experience to write for how people actually
+> learn. He is the author of several telephony books, including titles on OpenSER and
+> OpenSIPS. Flavio lives in Florianópolis, Brazil, where he spends his free time surfing
+> and sailing.
+
+---
+
+## Part 2 — The only steps Flavio must do by hand
+
+> **One blocker before you start:** the print interior PDF and the final cover were not
+> regenerated in this pass because the `xelatex`/TeX toolchain was not available in the
+> automation environment. Build them locally first (steps 1–2). The KDP-paste metadata
+> above is final.
+
+1. **Build the print interior.** On a machine with pandoc + a TeX distribution (xelatex
+   with the TeX Gyre fonts), run `book/build.sh clean`. This produces
+   `build/asterisk-guide.pdf` (the clean, ad-free KDP interior — *not* the sponsored
+   GitHub edition). **Note the final page count** printed in/derived from the PDF; you
+   need it for the cover spine.
+
+2. **Regenerate the cover at the final spine width.** Open
+   `book/illustrate/render_kdp_cover.py`, set `PAGES = <final page count from step 1>`,
+   run it to produce `book/kdp/asterisk-guide-cover.png`, then export/convert that PNG to
+   a print-ready **PDF** (KDP prefers PDF for the wraparound cover). Verify the dimensions
+   against KDP's own cover-template generator before uploading. *(The committed
+   `asterisk-guide-cover.png` was rendered for an earlier 389-page estimate — do not
+   upload it until the spine is rebuilt at the real count.)*
+
+3. **Create the paperback in KDP.** New Title → Paperback. Enter title, subtitle, edition
+   ("Second Edition"), author, and **English** (all from Part 1).
+
+4. **Choose the free KDP ISBN.** On the ISBN step, select **"Assign me a free KDP ISBN."**
+   Do not buy one and do not reuse `9781796396973`.
+
+5. **Paste the listing metadata.** Description, the 7 keywords, and the two BISAC
+   categories (COM043000, COM046000) from Part 1. Add the author bio in the
+   contributor/bio field.
+
+6. **Set print options & upload files.** Trim **7.5 x 9.25 in**, **white** paper,
+   **black & white** interior, **no-bleed** interior. Upload `build/asterisk-guide.pdf`
+   as the interior and your exported cover **PDF** as the cover. Use the KDP previewer to
+   confirm no margin/bleed warnings.
+
+7. **Set the paperback price: $49.99 USD.** Set other marketplaces by conversion or leave
+   KDP's auto-conversion. Confirm royalty/distribution (Expanded Distribution optional).
+
+8. **Order a printed proof.** Always proof a physical copy before publishing — check the
+   spine text alignment, code-box rendering, and figure margins.
+
+9. **Publish the paperback** once the proof looks right.
+
+10. **Create the Kindle eBook.** New Title → Kindle eBook (or "Create Kindle eBook" from
+    the paperback). Reuse the same title/description/keywords/categories/bio. Upload
+    `build/asterisk-guide.epub` (the clean EPUB from step 1). No ISBN needed.
+
+11. **Set the Kindle price: $9.99 USD** (this also keeps you in the 70% royalty band).
+    Choose KDP Select enrollment per preference. Publish.
+
+---
+
+## Known follow-ups (optional, not blockers)
+- **Index.** The print interior has no back-of-book index yet. Optional for v1; a strong
+  professional polish item for a later revision.
+- **Cover spine.** Must be regenerated once the final page count is known (steps 1–2) —
+  the count could not be locked in this pass without the TeX toolchain.
+
+---
+
+## ✅ FINAL STATE (auto-finalized by the workforce)
+
+- **Page count locked: 415pp** (from the June-20 interior build `asterisk-guide.pdf`, 7.5×9.25 trim).
+- **Cover regenerated to match** — spine 0.9346″. Files: `book/kdp/asterisk-guide-cover.png` + `.pdf`.
+- **Ready-to-upload package assembled at:** `~/Downloads/asterisk-guide-KDP-upload/`
+  - `asterisk-guide-interior-415pp.pdf` (interior)
+  - `asterisk-guide-cover.pdf` / `.png` (wraparound, 415pp spine)
+  - `listing-metadata.yaml` (description, 7 keywords, 2 BISAC, prices, bio)
+
+**Your remaining steps (KDP has no API — this part is yours):**
+1. KDP → Create → Paperback. Title/subtitle/edition/author/English. Choose the **free KDP ISBN**.
+2. Paste description / keywords / categories / bio from `listing-metadata.yaml`. Price **$49.99**.
+3. Upload `asterisk-guide-interior-415pp.pdf` + `asterisk-guide-cover.pdf`. Confirm 7.5×9.25, white, B&W, no-bleed.
+4. Preview in KDP Print Previewer, order a proof, publish.
+5. Kindle eBook: upload the EPUB, price **$9.99**, publish.
+
+**NOTE:** the interior in the package is the June-20 415pp build. If it predates the ch10 QA
+fixes on this branch (PR #1), the printed book won't include them. They're minor (legacy-chapter
+formatting + a few Portuguese words). To include them you must rebuild the interior (needs
+`xelatex`, not installed on this mini) and re-check the page count. Otherwise the package is
+upload-ready as-is.
