+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+## 🧭 Sobre PageTop
+
+[PageTop](https://docs.rs/pagetop) es un entorno de desarrollo que reivindica la esencia de la web
+clásica para crear soluciones web SSR (*renderizadas en el servidor*) modulares, extensibles y
+configurables, basadas en HTML, CSS y JavaScript.
+
+
+## ⚡️ Guía rápida
+
+**Añade la dependencia** a tu `Cargo.toml` activando el motor de base de datos que necesites:
+
+```toml
+[dependencies]
+pagetop-seaorm = { version = "...", features = ["sqlite"] }
+```
+
+Las *features* disponibles son `mysql`, `postgres` y `sqlite`.
+
+**Configura la conexión** en el archivo de configuración de la aplicación:
+
+```toml
+[database]
+db_type = "sqlite"
+db_name = "my_app.db"
+max_pool_size = 5
+```
+
+Para MySQL o PostgreSQL añade también `db_user`, `db_pass` y `db_host`. El campo `db_port` es
+opcional; si se omite se usa el puerto predeterminado del motor.
+
+**Declara la extensión** en tu aplicación o en la extensión que la requiera:
+
+```rust,ignore
+use pagetop::prelude::*;
+
+struct MyApp;
+
+impl Extension for MyApp {
+    fn dependencies(&self) -> Vec<ExtensionRef> {
+        vec![
+            &pagetop_seaorm::SeaORM,
+        ]
+    }
+
+    fn initialize(&self) {
+        install_migrations!(m20240101_000001_create_users_table);
+    }
+}
+
+#[pagetop::main]
+async fn main() -> std::io::Result<()> {
+    Application::prepare(&MyApp).run()?.await
+}
+```
+
+**Escribe las migraciones** usando la API de SeaORM:
+
+```rust,no_run
+use pagetop_seaorm::migration::*;
+
+pub struct Migration;
+
+#[async_trait::async_trait]
+impl MigrationTrait for Migration {
+    async fn up(&self, manager: &SchemaManager) -> Result<(), DbErr> {
+        manager
+            .create_table(
+                table_auto(Users::Table)
+                    .col(pk_auto(Users::Id))
+                    .col(string_uniq(Users::Email))
+                    .to_owned(),
+            )
+            .await
+    }
+}
+
+#[derive(DeriveIden)]
+enum Users {
+    Table,
+    Id,
+    Email,
+}
+```
+
+
+## 📚 Créditos
+
+Este *crate* se apoya en bibliotecas del ecosistema [SeaQL](https://github.com/SeaQL) como:
+
+* [SeaORM](https://www.sea-ql.org/SeaORM), ORM asíncrono que usa internamente
+  [SQLx](https://github.com/launchbadge/sqlx) para el acceso y la ejecución de consultas a la base
+  de datos.
+
+* [SeaQuery](https://github.com/SeaQL/sea-query), generador de consultas SQL sobre el que se
+  construye el motor de migraciones y los *helpers* de esquema.
+
+* [sea-schema](https://github.com/SeaQL/sea-schema), librería de introspección de esquemas SQL,
+  usada por el módulo de migraciones para interrogar la estructura real de la base de datos (tablas,
+  columnas, índices y claves externas).
+
+El módulo de migraciones (`src/migration/`) incorpora una adaptación de
+[sea-orm-migration](https://crates.io/crates/sea-orm-migration). El código que se integra procede de
+la versión [**1.1.20**](https://github.com/SeaQL/sea-orm/tree/1.1.20/sea-orm-migration) en lugar de
+usarlo como dependencia ya que su paradigma de CLI no es compatible con el ciclo de vida de las
+extensiones de PageTop, donde las migraciones deben ejecutarse durante la inicialización de cada
+extensión. Los ficheros adaptados del original son:
+
+| Archivos              | Observaciones                                                            |
+|-----------------------|--------------------------------------------------------------------------|
+| `lib.rs`              | Incluido en `migration.rs`, descarta módulos y exportaciones del CLI     |
+| `connection.rs`       | Integración completa                                                     |
+| `manager.rs`          | Adapta *features* propias                                                |
+| `migrator.rs`         | Adapta *features* propias y omite gestión de errores del CLI             |
+| `prelude.rs`          | Absorbido en `migration.rs`, descarta exportaciones del CLI              |
+| `schema.rs`           | Integra con ajustes, original de [loco](https://github.com/loco-rs/loco) |
+| `seaql_migrations.rs` | Integración completa                                                     |
+
+
+## 🚧 Advertencia
+
+**PageTop** es un proyecto personal para aprender [Rust](https://www.rust-lang.org/es) y conocer su
+ecosistema. Su API está sujeta a cambios frecuentes. No se recomienda su uso en producción, al menos
+hasta que se libere la versión **1.0.0**.
