+## Template Cheat Sheet
+
+### 1. Global objects injected into every `.erb`
+
+| Variable | Type          | Meaning                                                         |
+| -------- | ------------- | --------------------------------------------------------------- |
+| `@schema` | `Hash`        | Full JSON project skeleton.                                    |
+| `@entities` | `Array<Hash>` | Shortcut for `@schema['entities']`.                           |
+| `@migrations`, `@seeds` | `Array`        | Raw migration / seed arrays.                          |
+| `@project_with_web_site` | `Boolean`     | `true` if the project includes a public web-site.     |
+| `@component_types` | `Array<String>` | Unique list of component types used by the web-site.   |
+
+---
+
+### 2. Extra objects available **when the file/dir name contains `((name))`, `{{Name}}`, etc.**
+
+| Variable     | Type            | Meaning                                                           |
+| ------------ | --------------- | ----------------------------------------------------------------- |
+| `@name`      | `String`        | Current entity name (`snake_case`).                               |
+| `@entity`    | `Hash`          | Full entity record.                                               |
+| `@fields`    | `Array<Hash>`   | Shortcut for `@entity['fields']`.                                 |
+| `@all_fields`| `Array<Hash>`   | All fields from all entities; each field has `field['entity_name']`. |
+
+---
+
+### 3. Single `field` structure
+
+````
+field = {
+  '@name'     => 'firstName',
+  '@name_cap' => 'FirstName',
+  '@type'     => 'string',
+  '@ref'      => 'users',          # present only for relations
+  'title'     => 'First Name',
+  'unique'    => false,
+  # …plus any other keys from the schema
+}
+````
+### 4. Placeholder macros
+
+| Macro                     | Replaced by                  |
+|---------------------------|------------------------------|
+| `((name))` / `{{name}}`   | `users`                      |
+| `((Name))` / `{{Name}}`   | `Users`                      |
+| `((NAME))`                | `USERS`                      |
+| `{{migration-timestamp}}` | *Epoch ms* of the migration  |
+| `{{seed-timestamp}}`      | `YYYYMMDDHHMMSS` of the seed |
+
+*Any path that contains one of these tokens is cloned for **each** entity.*
+
+---
+
+### 6. Worked example
+
+```erb
+form_fields = @fields.select { |f| f['@type'] == 'relation_one' }
+form_fields.each do |f|
+  await ((name)).set<%= f['@name_cap'] %>(data.<%= f['@name'] %> || null, { transaction })
+end
+```
+## More ERB-style snippets
+
+### A. Simple sidebar route list
+
+
+<!-- sidebarRoutes.ts -->
+```erb
+export const routes = [
+<% @entities.each_with_index do |e, i| %>
+  { path: '/<%= e['@name'] %>', label: '<%= e['@name_cap'] %>' }<%= ',' unless i == @entities.size - 1 %>
+<% end %>
+];
+```
+### Sequelize model attributes (primitive fields only)
+```erb
+  attributes: {
+<% @fields.select { |f| %w[string int decimal boolean date datetime enum].include?(f['@type']) }.each do |f| %>
+  <%= f['@name'] %>: {
+    type: DataTypes.<%= get_sequelize_field_type(f['@type']) %>,
+  },
+<% end %>
+},
+```
+
+### TypeScript enums for every enum field in every entity
+```erb
+<!-- enums.ts -->
+<% @entities.each do |e| %>
+    <% e['fields'].select { |f| f['@type'] == 'enum' }.each do |f| %>
+    export enum <%= e['@name_cap'] %><%= f['@name_cap'] %>Enum {
+        <% f['options'].each do |o| %>
+          <%= o.upcase %> = '<%= o %>',
+        <% end %>
+    }
+    <% end %>
+<% end %>
+```
+
+### Generating a REST-style URL map (all entities → list & detail)
+```erb
+# migration_log.md
+<% @migrations.each do |m| %>
+### <%= Time.at(m['time'] / 1000).utc.strftime('%Y-%m-%d %H:%M:%S') %>
+
+<% m['changes'].each do |ch| %>
+- **<%= ch['type'] %>** on **<%= ch.dig('payload','table') || ch['tables'] %>**
+<% end %>
+
+<% end %>
+```

+Required Notice: Copyright © 2025 Flatlogic sp. z o.o. (https://flatlogic.com)
+
+## Acceptance
+In order to get any licence under these terms, you must agree to them as both strict obligations and conditions to all your licences.
+
+## Copyright Licence
+The licensor grants you a copyright licence for the software to do everything you might do with the software that would otherwise infringe the licensor’s copyright in it for any permitted purpose. However, you may only distribute the software according to **Distribution Licence** and make changes or new works based on the software according to **Changes and New Works Licence**.
+
+## Distribution Licence
+The licensor grants you an additional copyright licence to distribute copies of the software. Your licence to distribute covers distributing the software with changes and new works permitted by **Changes and New Works Licence**.
+
+## Notices
+You must ensure that anyone who gets a copy of any part of the software from you also gets a copy of these terms or the URL for them above, as well as copies of any plain‑text lines beginning with `Required Notice:` that the licensor provided with the software. For example:
+
+> Required Notice: Copyright © 2025 Flatlogic sp. z o.o. (https://flatlogic.com)
+
+## Changes and New Works Licence
+The licensor grants you an additional copyright licence to make changes and new works based on the software for any permitted purpose.
+
+## Patent Licence
+The licensor grants you a patent licence for the software that covers patent claims the licensor can license, or becomes able to license, that you would infringe by using the software.
+
+## Noncompete
+Any purpose is a permitted purpose, **except for providing any product that competes with the software or any product the licensor or any of its affiliates provides using the software.**
+
+## Competition
+Goods and services compete even when they provide functionality through different kinds of interfaces or for different technical platforms. Applications can compete with services, libraries with plugins, frameworks with development tools, and so on, even if they’re written in different programming languages or for different computer architectures. Goods and services compete even when provided free of charge.
+
+If you market a product as a practical substitute for the software or another product, it definitely competes.
+
+## New Products
+If you are using the software to provide a product that does not compete, but the licensor or any of its affiliates brings your product into competition by providing a new version of the software or another product using the software, you may continue using versions of the software available under these terms beforehand to provide your competing product, but not any later versions.
+
+## Discontinued Products
+You may begin using the software to compete with a product or service that the licensor or any of its affiliates has stopped providing, unless the licensor includes a plain‑text line beginning with `Licensor Line of Business:` with the software that mentions that line of business. For example:
+
+> Licensor Line of Business: Flatlogic Generator SaaS (https://flatlogic.com/generator)
+
+## Sales of Business
+If the licensor or any of its affiliates sells a line of business developing the software or using the software to provide a product, the buyer can also enforce **Noncompete** for that product.
+
+## Fair Use
+You may have “fair use” rights for the software under the law. These terms do not limit them.
+
+## No Other Rights
+These terms do not allow you to sublicense or transfer any of your licences to anyone else, or prevent the licensor from granting licences to anyone else. These terms do not imply any other licences.
+
+## Patent Defence
+If you make any written claim that the software infringes or contributes to infringement of any patent, your patent licence for the software granted under these terms ends immediately. If your company makes such a claim, your patent licence ends immediately for work on behalf of your company.
+
+## Violations
+The first time you are notified in writing that you have violated any of these terms, or done anything with the software not covered by your licences, your licences can nonetheless continue if you come into full compliance with these terms, and take practical steps to correct past violations, within 32 days of receiving notice. Otherwise, all your licences end immediately.
+
+## No Liability
+As far as the law allows, the software comes as‑is, without any warranty or condition, and the licensor will not be liable to you for any damages arising out of these terms or the use or nature of the software, under any kind of legal claim.
+
+## Definitions
+*The licensor* is Flatlogic sp. z o.o., and *the software* is the **Flatlogic Community Template** we make available under these terms.
+
+*A product* can be a good or service, or a combination of them.
+
+*You* refers to the individual or entity agreeing to these terms.
+
+*Your company* is any legal entity, sole proprietorship, or other kind of organisation that you work for, plus all its affiliates.
+
+*Affiliates* means the other organisations that an organisation has control over, is under the control of, or is under common control with.
+
+*Control* means ownership of substantially all the assets of an entity, or the power to direct its management and policies by vote, contract, or otherwise. Control can be direct or indirect.
+
+*Your licences* are all the licences granted to you for the software under these terms.
+
+*Use* means anything you do with the software requiring one of your licences.

+| Front‑end | **React JS**         |
+| Back‑end  | **Node JS**          |
+| Database  | **PostgreSQL**       |
+| Container | **Docker & Compose** |
+
+---
+
+## 1 — Run Locally (without Docker)
+
+### 1.1 Backend
+
+```bash
+cd backend
+# install dependencies
+yarn install
+```
+
+\#### Configure PostgreSQL
+
+<details>
+<summary><strong>macOS</strong></summary>
+
+```bash
+brew install postgres
+```
+
+</details>
+<details>
+<summary><strong>Ubuntu</strong></summary>
+
+```bash
+sudo apt update
+sudo apt install postgresql postgresql-contrib
+```
+
+</details>
+
+\##### Create DB & Admin User
+
+```bash
+# log in as default super‑user
+psql postgres -U postgres
+
+-- inside psql
+CREATE ROLE admin WITH LOGIN PASSWORD 'admin_pass';
+ALTER ROLE admin CREATEDB;
+\q
+
+# log in as the new user
+psql postgres -U admin
+
+-- inside psql
+CREATE DATABASE db_<your_project_name>;
+GRANT ALL PRIVILEGES ON DATABASE db_<your_project_name> TO admin;
+\q
+```
+
+\##### Migrate & Start
+
+```bash
+yarn db:create   # generate schema
+yarn start       # production build
+```
+
+### 1.2 Frontend
+
+```bash
+cd frontend
+yarn install
+yarn start
+```
+
+> Front‑end dev‑server runs at **[http://localhost:3000](http://localhost:3000)** by default.
+
+---
+
+## 2 — Run with Docker
+
+```bash
+cd docker
+chmod +x wait-for-it.sh start-backend.sh
+```
+
+| Scenario                  | Command                            |
+| ------------------------- | ---------------------------------- |
+| **Fresh DB volume**       | `rm -rf data && docker-compose up` |
+| **Reuse existing volume** | `docker-compose up`                |
+
+Then open **[http://localhost:3000](http://localhost:3000)**.
+
+Stop services with **Ctrl + C** or:
+
+```bash
+docker-compose down
+```
+
+> **Heads‑up:** Files inside the `docker/` folder and the root `Dockerfile` are used for cloud deployment. Changing them may break the pipeline.
+
+---
+
+## Folder Structure (top‑level)
+
+```text
+├── backend/          # Node JS API & services
+├── frontend/         # React application
+├── docker/           # Compose files & helper scripts
+└── README.md         # (this file)
+```
+
+---
+
+## Troubleshooting
+
+### “connection refused”
+
+1. Port closed or backlog full.
+2. Firewall (local or network).
+3. Service not running.
+
+Verify with:
+
+```bash
+telnet <host> <port>
+```
+
+### macOS
+
+```bash
+sudo service ssh status
+```
+
+### Ubuntu – IP conflict check
+
+```bash
+arp-scan -I eth0 -l | grep <ipaddress>
+arping <ipaddress>
+```
+
+### Reset PostgreSQL schema (macOS example)
+
+```sql
+DROP SCHEMA public CASCADE;
+CREATE SCHEMA public;
+GRANT ALL ON SCHEMA public TO postgres;
+GRANT ALL ON SCHEMA public TO public;
+```
+

+## Cheat‑sheet
+
+| Task                    | Command                            |
+| ----------------------- | ---------------------------------- |
+| **Create DB schema**    | `yarn db:create`                   |
+| **Start backend**       | `yarn start`                       |
+| **Start dev front‑end** | `cd frontend && yarn start`        |
+| **Compose up (fresh)**  | `rm -rf data && docker-compose up` |
+| **Compose down**        | `docker-compose down`              |

+##### Install local dependencies:
+- `yarn install`
+
+------------
+
+##### Adjust local db:
+###### 1.  Install postgres:
+ - MacOS:
+   - `brew install postgres`
+
+- Ubuntu:
+  - `sudo apt update`
+  - `sudo apt install postgresql postgresql-contrib`
+
+###### 2. Create db and admin user:
+ - Before run and test connection, make sure you have created a database as described in the above configuration. You can use the `psql` command to create a user and database.
+   - `psql postgres --u postgres`
+
+- Next, type this command for creating a new user with password then give access for creating the database.
+  - `postgres-# CREATE ROLE admin WITH LOGIN PASSWORD 'admin_pass';`
+  - `postgres-# ALTER ROLE admin CREATEDB;`
+
+- Quit `psql` then log in again using the new user that previously created.
+  - `postgres-# \q`
+  - `psql postgres -U admin`
+
+- Type this command to creating a new database.
+  - `postgres=> CREATE DATABASE db_akash_techno;`
+
+- Then give that new user privileges to the new database then quit the `psql`.
+  - `postgres=> GRANT ALL PRIVILEGES ON DATABASE db_akash_techno TO admin;`
+  - `postgres=> \q`
