 for editing [Bosh](https://bosh.io/) Deployment Manifest files.
 
-## Usage
-
-### Activating the Editor
-
-The Bosh editor automatically activates when the name of the  `.yml` file you are editing 
-follows a certain pattern:
-
-  - `**/*deployment*.yml` : activates support for bosh manifest file.
-  
-You can also define your own patterns and map them to the language-id `bosh-deployment-manifest` 
-by defining `files.associations` in workspace settings. 
-See [vscode documentation](https://code.visualstudio.com/Docs/languages/overview#_adding-a-file-extension-to-a-language) for details.

-### Targetting a specific Director
-
-Some Validation and Content Assist use information dymanically retrieved from an active Bosh director.
-For these feature to work it is required that you 
-
-- have the bosh cli V2 installed (information is obtained by executing commands using the V2 cli)
-- target a director by setting the `BOSH_ENVIROMENT` variable.
-
-You can verify that you have set things up right by executing command:
-
-```
-bosh cloud-config --json
-```
-
-If setup correctly, it should return information about the cloud-config on your intended bosh director/environment.

+  - `**/*deployment*.yml` : activates support for bosh manifest file.

+
+### Targetting a specific Director
+
+Some of the Validations and Content Assist depend on information dymanically retrieved from an active Bosh director.
+This information is retrieve by the editor by executing commands using the Bosh CLI. For this to work the CLI (V2 
+CLI is required) and editor have to be installed and configured correctly.
+
+There are two ways to set things up:
+
+#### Explicitly Configure the CLI:
+
+From vscode, press `CTRL-SHIFT-P` and type `Settings` then select either "Open User Settings" or "Open Workspace Settings".
+The bosh cli can be conigured by specifying values for keys of the form `bosh.cli.XXX`. Content assist and hover docs 
+explain the meaning of the available keys.
+
+#### Implictly Configure the CLI:
+
+If the bosh cli is not explicitly configure it will, by default try to execute commands like `bosh cloud-config --json` 
+without an explicit `-e ...` argument to target a specific director. This works only if you ensure that the editor
+process executes with a proper set of environment variables:
+
+- `PATH`: must be set so that `bosh` command can be found and refers to the V2 CLI.
+- `BOSH_ENVIRONMENT`: must be set to point to the bosh director you want to target.
+
+If you start vscode from a terminal, you can verify that things are setup correctly by executing command:
+
+     bosh cloud-config
+
+If that command executes without any errors and returns the cloud-config, then things are setup correctly 
+and if you launch vscode from that same terminal the dynamic CA and linting should work correctly.
