How to run this site locally

This is a Jekyll site (GitHub Pages–compatible). Follow these steps to build and serve it on your machine.

Prerequisites

Ruby (2.6 or newer; check with ruby -v)
Bundler — the project is locked to Bundler 2.3.23 (see Gemfile.lock). If bundle exec fails with a “Could not find ‘bundler’ (2.3.23)” error, install that version:
```
gem install bundler:2.3.23
```
Or install into the project only (no system-wide install):
```
mkdir -p vendor/bundle
gem install bundler:2.3.23 --install-dir ./vendor/bundle
```
Then run Jekyll with the project’s Bundler:
```
GEM_HOME=./vendor/bundle GEM_PATH=./vendor/bundle bundle _2.3.23_ exec jekyll serve
```

Go to the project directory
```
cd /path/to/abidulrmdn.github.io
```
Install dependencies
```
bundle install
```
(If you use the vendor/bundle setup above, prefix with GEM_HOME=./vendor/bundle GEM_PATH=./vendor/bundle bundle _2.3.23_ install.)

Build and serve the site

bundle exec jekyll serve

Or, with the project-local Bundler:

GEM_HOME=./vendor/bundle GEM_PATH=./vendor/bundle bundle _2.3.23_ exec jekyll serve

Open in a browser

Go to http://localhost:4000. The server will watch for file changes and regenerate the site when you edit content.

Incremental build (faster rebuilds):
bundle exec jekyll serve --incremental
Custom host/port:
bundle exec jekyll serve --host 0.0.0.0 --port 4001
Production build only (output in _site/):
bundle exec jekyll build
