-## Overview
-
-RelSpec provides bidirectional conversion, comparison, and validation of database specification formats, allowing you to:
-- Inspect live databases and extract their structure
-- Validate schemas against configurable rules and naming conventions
-- Convert between different ORM models (GORM, Bun, etc.)
-- Transform legacy schema definitions (Clarion DCTX, XML, JSON, etc.)
-- Generate standardized specification files (JSON, YAML, etc.)
-- Compare database schemas and track changes

-## Usage
+## Supported Formats
 
-### Interactive Schema Editor
+| Direction | Formats |
+|-----------|---------|
+| **Readers** | `bun` `dbml` `dctx` `drawdb` `drizzle` `gorm` `graphql` `json` `mssql` `pgsql` `prisma` `sqldir` `sqlite` `typeorm` `yaml` |

+
+## Commands
+
+### `convert` — Schema conversion
 
 ```bash
-# Launch interactive editor with a DBML schema
-relspec edit --from dbml --from-path schema.dbml --to dbml --to-path schema.dbml
+# PostgreSQL → GORM models
+relspec convert --from pgsql --from-conn "postgres://user:pass@localhost/mydb" \
+                --to gorm --to-path models/ --package models
 
-# Edit PostgreSQL database in place
-relspec edit --from pgsql --from-conn "postgres://user:pass@localhost/mydb" \
-             --to pgsql --to-conn "postgres://user:pass@localhost/mydb"
+# DBML → PostgreSQL DDL
+relspec convert --from dbml --from-path schema.dbml --to pgsql --to-path schema.sql
 
-# Edit JSON schema and save as GORM models
-relspec edit --from json --from-path db.json --to gorm --to-path models/
+# PostgreSQL → SQLite (auto flattens schemas)
+relspec convert --from pgsql --from-conn "postgres://..." --to sqlite --to-path schema.sql
+
+# Multiple input files merged
+relspec convert --from json --from-list "a.json,b.json" --to yaml --to-path merged.yaml
 ```
 
-The `edit` command launches an interactive terminal user interface where you can:
-- Browse and navigate your database structure
-- Create, modify, and delete schemas, tables, and columns
-- Configure column properties, constraints, and relationships
-- Save changes to various formats
-- Import and merge schemas from other databases
-
-### Schema Merging
+### `merge` — Additive schema merge (never modifies existing items)
 
 ```bash
-# Merge two JSON schemas (additive merge - adds missing items only)
+# Merge two JSON schemas
 relspec merge --target json --target-path base.json \
               --source json --source-path additions.json \
               --output json --output-path merged.json
 
-# Merge PostgreSQL database into JSON, skipping specific tables
+# Merge PostgreSQL into JSON, skipping tables
 relspec merge --target json --target-path current.json \
-              --source pgsql --source-conn "postgres://user:pass@localhost/source_db" \
+              --source pgsql --source-conn "postgres://user:pass@localhost/db" \
               --output json --output-path updated.json \
               --skip-tables "audit_log,temp_tables"
-
-# Cross-format merge (DBML + YAML → JSON)
-relspec merge --target dbml --target-path base.dbml \
-              --source yaml --source-path additions.yaml \
-              --output json --output-path result.json \
-              --skip-relations --skip-views
 ```
 
-The `merge` command combines two database schemas additively:
-- Adds missing schemas, tables, columns, and other objects
-- Never modifies or deletes existing items (safe operation)
-- Supports selective merging with skip options (domains, relations, enums, views, sequences, specific tables)
-- Works across any combination of supported formats
-- Perfect for integrating multiple schema definitions or applying patches
+Skip flags: `--skip-relations` `--skip-views` `--skip-domains` `--skip-enums` `--skip-sequences`
 
-### Schema Conversion
+### `inspect` — Schema validation / linting
 
 ```bash
-# Convert PostgreSQL database to GORM models
-relspec convert --from pgsql --from-conn "postgres://user:pass@localhost/mydb" \
-                --to gorm --to-path models/ --package models
-
-# Convert GORM models to Bun
-relspec convert --from gorm --from-path models.go \
-                --to bun --to-path bun_models.go --package models
-
-# Export database schema to JSON
-relspec convert --from pgsql --from-conn "postgres://..." \
-                --to json --to-path schema.json
-
-# Convert DBML to PostgreSQL SQL
-relspec convert --from dbml --from-path schema.dbml \
-                --to pgsql --to-path schema.sql
-
-# Convert PostgreSQL database to SQLite (with automatic schema flattening)
-relspec convert --from pgsql --from-conn "postgres://..." \
-                --to sqlite --to-path sqlite_schema.sql
-```
-
-### Schema Validation
-
-```bash
-# Validate a PostgreSQL database with default rules
+# Validate PostgreSQL database
 relspec inspect --from pgsql --from-conn "postgres://user:pass@localhost/mydb"
 
-# Validate DBML file with custom rules
+# Validate DBML with custom rules
 relspec inspect --from dbml --from-path schema.dbml --rules .relspec-rules.yaml
 
-# Generate JSON validation report
-relspec inspect --from json --from-path db.json \
-                --output-format json --output report.json
+# JSON report output
+relspec inspect --from json --from-path db.json --output-format json --output report.json
 
-# Validate specific schema only
+# Filter to specific schema
 relspec inspect --from pgsql --from-conn "..." --schema public
 ```
 
-### Schema Comparison
+Rules: naming conventions, PK/FK standards, missing indexes, reserved keywords, circular dependencies.
+
+### `diff` — Schema comparison
 
 ```bash
-# Compare two database schemas
 relspec diff --from pgsql --from-conn "postgres://localhost/db1" \
              --to pgsql --to-conn "postgres://localhost/db2"
 ```
 
+### `templ` — Custom template rendering
+
+```bash
+# Render database schema to Markdown docs
+relspec templ --from pgsql --from-conn "postgres://user:pass@localhost/db" \
+              --template docs.tmpl --output schema-docs.md
+
+# One TypeScript file per table
+relspec templ --from dbml --from-path schema.dbml \
+              --template ts-model.tmpl --mode table \
+              --output ./models/ --filename-pattern "{{.Name | toCamelCase}}.ts"
+```
+
+Modes: `database` (default) · `schema` · `table` · `script`
+
+Template functions: string utils (`toCamelCase`, `toSnakeCase`, `pluralize`, …), type converters (`sqlToGo`, `sqlToTypeScript`, …), filters, loop helpers, safe access.
+
+### `edit` — Interactive TUI editor
+
+```bash
+# Edit DBML schema interactively
+relspec edit --from dbml --from-path schema.dbml --to dbml --to-path schema.dbml
+
+# Edit live PostgreSQL database
+relspec edit --from pgsql --from-conn "postgres://user:pass@localhost/mydb" \
+             --to pgsql --to-conn "postgres://user:pass@localhost/mydb"
+```

+
+# From Scripts to RelSpec: What Years of Database Pain Taught Me
+
+It started as a need.
+A problem I’ve carried with me since my early PHP days.
+
+Every project meant doing the same work again. Same patterns, same fixes—just in a different codebase.
+It became frustrating fast.
+
+I wanted something solid. Not another workaround.
+
+## The Early Tools Phase
+
+Like most things in development, it began small.
+
+A simple PHP script.
+Then a few Python scripts.
+
+Just tools—nothing fancy. The goal was straightforward: generate code faster and remove repetitive work. I even experimented with Clarion templates at one point, trying to bend existing systems into something useful.
+
+Then came SQL scripts.
+Then PostgreSQL migration stored procedures.
+Then small Go programs using templates.
+
+Each step was solving a problem I had at the time. Nothing unified. Nothing polished. Just survival tools.
+
+---
+
+## Argitek: The First Real Attempt
+
+Eventually, those scattered ideas turned into something more structured: Argitek.
+
+Argitek powered a few real systems, including Powerbid. On paper, it sounded solid:
+
+> “Argitek Next is a powerful code generation tool designed to streamline your development workflow.”
+
+And technically, it worked.
+
+It could generate code from predefined templates, adapt to different scenarios, and reduce repetitive work. But something was off.
+
+It never felt *complete*.
+Not something I could confidently release.
+
+So I did what many developers do with almost-good-enough tools—I parked it.
+
+---
+
+## The Breaking Point: Database Migrations
+
+Over the years, one problem kept coming back:
+
+Database migrations.
+
+Not the clean, theoretical kind. The real ones.
+
+* PostgreSQL to ORM mismatches
+* DBML to SQL hacks
+* GORM inconsistencies
+* Manual fixes after “automated” migrations failed
+
+It was always messy. Always unpredictable. Always more work than expected.
+
+By 2025, after a particularly tough year, I had accumulated enough of these problems to stop ignoring them.
+
+---
+
+## December 2025: RelSpecGo Begins
+
+In December 2025, I bootstrapped something new:
+
+**RelSpecGo**
+
+It started simple:
+
+* Initial LICENSE
+* Basic configuration
+* A direction
+
+By late December:
+
+* SQL writer implemented
+* Diff command added
+
+January 2026:
+
+* Documentation
+
+February 2026:
+
+* Schema editor UI (focused on relationships)
+* MSSQL DDL writer
+* Template support with `--from-list`
+
+---
+
+## April 2026: A Real Tool Emerges
+
+By April 2026, it became something I could finally stand behind.
+
+RelSpecGo reached version **1.0.44**, with:
+
+* Packaging for AUR, Debian, and RPM
+* Updated documentation and README
+* A full toolchain for:
+
+  * Convert
+  * Merge
+  * Inspect
+  * Diff
+  * Template
+  * Edit
+
+Support includes:
+
+* bun
+* dbml
+* drizzle
+* gorm
+* prisma
+* mssql
+* pgsql
+* sqlite
+
+Plus:
+
+* TUI editor
+* Template engine
+* Bidirectional schema handling
+
+👉 RelSpecGo: [https://git.warky.dev/wdevs/relspecgo](https://git.warky.dev/wdevs/relspecgo)
+
+This wasn’t just another generator anymore.
+It became a system for managing *database truth*.
+
+---
+
+## Lessons Learned (The Hard Way)
+
+This journey wasn’t about tools. It was about understanding databases properly.
+
+Here are the principles that stuck:
+
+### 1. Data Loss Is Not Acceptable
+
+Changing table structures should **never** result in lost data. If it does, the process is broken.
+
+### 2. Minimal Beats Clever
+
+The simpler the system, the easier it is to trust—and to fix.
+
+### 3. Respect the Database
+
+If you fight database rules, you will lose. Stay aligned with them.
+
+### 4. Indexes and Keys Matter More Than You Think
+
+Performance and correctness both depend on them. Ignore them at your own risk.
+
+### 5. Version-Control Your Backend Logic
+
+SQL scripts, functions, migrations—these must live in version control. No exceptions.
+
+### 6. It’s Not Migration—It’s Adaptation
+
+You’re not just moving data. You’re fixing inconsistencies and aligning systems.
+
+### 7. Migrations Never Go as Planned
+
+Always assume something will break. Plan for it.
+
+### 8. One Source of Truth Is Non-Negotiable
+
+Your database schema must have a single, authoritative definition.
+
+### 9. ORM Mapping Is a First-Class Concern
+
+Your application models must reflect the database correctly. Drift causes bugs.
+
+### 10. Audit Trails Are Critical
+
+If you can’t track changes, you can’t trust your system.
+
+### 11. Manage Database Functions Properly
+
+They are part of your system—not an afterthought.
+
+### 12. If It’s Hard to Understand, It’s Too Complex
+
+Clarity is a feature. Complexity is technical debt.
+
+### 13. GUIDs Have Their Place
+
+Especially when moving data across systems. They solve real problems.
+
+### 14. But Simplicity Still Wins
+
+Numbered primary keys are predictable, efficient, and easy to reason about.
+
+### 15. JSON Is Power—Use It Carefully
+
+It adds flexibility, but too much turns structure into chaos.
+
+---
+
+## Closing Thoughts
+
+Looking back, this wasn’t about building a tool.
+
+It was about:
+
+* Reducing friction
+* Making systems predictable
+* Respecting the database as the core of the system
+
+RelSpecGo is just the current result of that journey.
+
+Not the end.
+
+Just the first version that feels *right*.
