-TODO Instructions
+### Step 1: Setup Skeleton
+
+First step towards making a choco package is initializing a base.
+
+The command `choco new -h` can teach you more about the `new` command, its usage, options, switches, and exit codes.
+
+Run the following command to setup the base
+
+```powershell
+choco new --name="apidash" --version="0.3.0" maintainername="foss42" maintainerrepo="https://github.com/foss42/apidash" --built-in-template
+```
+
+![choco folder structure](images/choco_create_structure.png)
+
+This creates the following folder structure
+
+```
+apidash
+├── ReadMe.md
+├── _TODO.txt
+├── apidash.nuspec
+└── tools
+    ├── chocolateybeforemodify.ps1
+    ├── chocolateyinstall.ps1
+    ├── chocolateyuninstall.ps1
+    ├── LICENSE.txt
+    └── VERIFICATION.txt
+```
+
+The files `ReadMe.md` and `_TODO.md` can be deleted before pushing.
+
+The files of our main interest are `chocolateyinstall.ps1` and `apidash.nuspec`.
+
+### Step 2: Editing `chocolateyinstall.ps1`
+
+Take a look at `chocolateyinstall.ps1` file. There are many comments stating the use case of each line itself.
+![chocolatelyinstall.ps1](images/choco_chocolateyinstall_ps1.png)
+
+Comments can bre remoed using the following command.
+```powershell
+$f='apidash\tools\chocolateyinstall.ps1'
+gc $f | ? {$_ -notmatch "^\s*#"} | % {$_ -replace '(^.*?)\s*? [^``]#.*','$1'} | Out-File $f+".~" -en utf8; mv -fo $f+".~" $f
+```
+
+Now our `chocolateyinstall.ps1` file is ready.
+
+### Step 3: Editing `apidash.nuspec`
+
+![final apidash.nuspec](images/choco_nuspec.png)
+
+### Step 4: Build the package
+
+All our files are ready, we just need to pack out files in a choco package with the extension `.nupkg`.
+
+Run the following command from the root of your directory:
+```powershell
+choco pack 
+```
+This command generates the `apidash.0.3.0.nupkg` file.
+
+### Step 5: Test the Package Locally
+
+Install the package locally using Chocolatey:
+```powershell
+choco install apidash -s .
+```
+Ensure the application installs correctly.

+
+### Step 6: Pre-Publishing - Update `LICENSE.txt` & `VERIFICATION.txt`
+
+Update `LICENSE.txt` with the actual **LICENSE **and `VERIFICATION.txt` accordingly.
+
+### Step 7: Publish the Package (Optional)
+
+To share the package, you can push it to a Chocolatey repository. For the official Chocolatey Community Repository, follow these steps:
+
+1. Create an account on the Chocolatey Community.
+2. Get an API key by navigating to your profile.
+3. Use the following command to push your package:
+```powershell
+choco push apidash.0.3.0.nupkg --source="https://push.chocolatey.org/" --api-key="YOUR_API_KEY"
+```
