+# Add CHANGE-ME
+
+We want to add `CHANGE-ME` because...
+
+- it works consistently across Windows, Mac, and Linux.
+
+This could be as simple as copying `_example`, updating the github releases
+info, and doing a find and replace on a few file system path names.

+# How to create a webi installer
+
+[![Video Tutorial: How to create a webi Installer](https://user-images.githubusercontent.com/122831/91064908-17f28100-e5ed-11ea-9cf0-ab3363cdf4f8.jpeg)](https://youtu.be/RDLyJtiyQHA)
+
+## Skills required
+
+- Basic Command Line knowledge (`mkdir`, `mv`, `ls`, `tar`, `unzip`, variables)
+
+## Steps
+
+1. Clone and setup the webi packages repo
+   ```bash
+   git clone git@github.com:webinstall/packages.git
+   pushd packages/
+   npm install
+   ```
+2. Copy the example template and update with info from Official Releases:
+   <https://github.com/___CHANGE/ME___/releases>
+   ```bash
+   rsync -av _example/ CHANGE-ME/
+   ```
+   - [ ] update `CHANGE-ME/release.js` to use the official repo
+   - [ ] Learn how `CHANGE-ME` unpacks (i.e. as a single file? as a .tar.gz? as
+         a .tar.gz with a folder named CHANGE-ME?)
+   - [ ] find and replace to change the name
+     - [ ] update `CHANGE-ME/install.sh` (see `bat` and `jq` as examples)
+     - [ ] update `CHANGE-ME/install.ps1` (see `bat` and `jq` as examples)
+3. Needs an updated tagline and cheat sheet
+   - [ ] update `CHANGE-ME/README.md`
+     - [ ] official URL
+     - [ ] tagline
+     - [ ] Switch versions
+     - [ ] description / summary
+     - [ ] General pointers on usage (and differences from `sed`)
+
+It's also okay to have multiple people work on part of this (i.e. the Cheat
+Sheet can be done independently from the `install.sh`)
