 System notes below.  If this doesn't help, then go to the Troubleshooting
 section, which includes instructions on how to contact us for help.
 
+Offline Build Notes
+-------------------
+
+It is common for packaging systems (e.g. NixOS, FreeBSD Ports Collection, pkgsrc, etc)
+to disable networking during builds.  This restriction requires all distribution files
+to be prepositioned after checksum verification as a prerequisite for the build.  The
+following steps have been successful in allowing Taskwarrior to be built in this
+environment:
+
+1. Extract all crates in a known location, e.g. ${WRKDIR}/cargo-crates
+This includes crates needed for corrosion (search for Cargo.lock files)
+
+2. Create .cargo-checksum.json for each crate
+For example:
+printf '{"package":"%s","files":{}}' $(sha256 -q ${DISTDIR}/rayon-core-1.12.1.tar.gz) \
+        > ${WRKDIR}/cargo-crates/rayon-core-1.12.1/.cargo-checksum.json
+
+3. Create a custom config.toml file
+For example, ${WRKDIR}/.cargo/config.toml
+[source.cargo]
+directory = '${WRKDIR}/cargo-crates'
+[source.crates-io]
+replace-with = 'cargo'
+
+4. After running cmake, configure cargo
+For example:
+cd ${WRKSRC} && ${SETENV} ${MAKE_ENV} ${CARGO_ENV} \
+  /usr/local/bin/cargo update \
+  --manifest-path ${WRKDIR}/.cargo/config.toml \
+  --verbose
+
+5. Set CARGO_HOME in environment
+For example
+CARGO_HOME=${WRKDIR}/.cargo
+
+The build and installation steps should be the same as a standard build
+at this point.

+.fi
+
+To create such a user, create a new policy in the IAM console, select the JSON
+option in the policy editor, and paste the policy. Click "Next" and give the
+policy a name such as "TaskwarriorSync". Next, create a new user, with a name
+of your choosing, select "Attach Policies Directly", and then choose the
+newly-created policy.
+
+You will need access keys configured for the new user. Find the user in the
+user list, open the "Security Credentials" tab, then click "Create access key"
+and follow the steps.
+
+At this point, you can choose how to provide those credentials to Taskwarrior.
+The simplest is to include them in the Taskwarrior configuration:
+
+.nf
+    $ task config sync.aws.region              <region>
+    $ task config sync.aws.bucket              <bucket-name>
+    $ task config sync.aws.access_key_id       <access-key-id>
+    $ task config sync.aws.secret_access_key   <secret-access-key>
+.fi
+
+Alternatively, you can set up an AWS CLI profile, using a profile name of your
+choosing such as "taskwarrior-creds":
+
+.nf
+    $ aws configure --profile taskwarrior-creds
+.fi
+
+Enter the access key ID and secret access key. The default region and format
+are not important. Then configure Taskwarrior with:
+
+.nf
+    $ task config sync.aws.region              <region>
+    $ task config sync.aws.bucket              <bucket-name>
+    $ task config sync.aws.profile             taskwarrior-creds
+.fi
+
+To use AWS's default credential sources, such as environment variables, the
+default profile, or an instance profile, set
+
+.nf
+    $ task config sync.aws.region              <region>
+    $ task config sync.aws.bucket              <bucket-name>
