+## Infrastructure-setup
+
+https://git.hamaralinux.org/hamara-developers/hamara-infra/blob/master/hetzner_setup.md
+
+## Build process
+
+### 1. Build hamara packages:
+
+Source Code: https://git.hamaralinux.org/devel/packages/swastik
+
+Build job: https://builds.hamaralinux.org/job/Hamara-Packages/
+
+
+This job will build the packages and copy them over to aptly container
+
+### 2. Create repo, clone upstream mirrors:
+
+Ref:  https://git.hamaralinux.org/hamara-developers/Documentation/blob/master/aptly/aptly-based-repository-setup.md
+
+Upstream Ref: https://www.aptly.info/doc/commands/
+
+
+```
+# create a repo for adding hamara-packages
+aptly repo create hamara-packages
+```
+```
+# add the packages delivered by jenkins job to repo
+aptly repo add hamara-packages /opt/aptly/hamara_custom_packages/
+```
+```
+# Create a snapshot of custom hamara-packages
+aptly create snapshot hamara-svastik-inhouse-<date> from repo hamara-packages
+```
+```
+# Merge all snapshots into one
+aptly snapshot merge hamara-svastik-merged hamara-svastik-inhouse-19052021 hamara-sugam-v3-non-free-18012021 hamara-sugam-v3-main-18012021 hamara-sugam-v3-contrib-18012021
+```
+
+```
+# Publish the snapshot Note: this step will ask for gpg password can get it from vault.hamaralinux.org
+aptly publish snapshot -architectures=amd64 -distribution=svastik hamara-svastik-merged
+```
+```
+# For updating mirrors
+
+aptly mirror update <mirror-name>
+```
+
+### 3. Building the ISO image
+
+Once the snapshot is published by aptly the HamaralinuxISObuilder job can be triggered to build and publish ISO image.
+
+Jenkins Job: https://builds.hamaralinux.org/job/HamaralinuxISObuilder/
