+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at mikefarah@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

 a lightweight and portable command-line YAML processor
 
 The aim of the project is to be the [jq](https://github.com/stedolan/jq) or sed of yaml files.
 
 ## Install
-On MacOS:
+
+### [Download the latest binary](https://github.com/mikefarah/yq/releases/latest)
+
+### MacOS:
 ```
 brew install yq
 ```
-On Ubuntu and other Linux distros supporting `snap` packages:
+
+### Ubuntu and other Linux distros supporting `snap` packages:
 ```
 snap install yq
 ```
-or, [Download latest binary](https://github.com/mikefarah/yq/releases/latest) or alternatively:
+
+#### Snap notes
+`yq` installs with [_strict confinement_](https://docs.snapcraft.io/snap-confinement/6233) in snap, this means it doesn't have direct access to root files. To read root files you can:
+
 ```
-go get github.com/mikefarah/yq
+sudo cat /etc/myfile | yq r - a.path
 ```
 
-## Run with Docker
+And to write to a root file you can either use [sponge](https://linux.die.net/man/1/sponge):
+```
+sudo cat /etc/myfile | yq w - a.path value | sudo sponge /etc/myfile
+```
+or write to a temporary file:
+```
+sudo cat /etc/myfile | yq w - a.path value | sudo tee /etc/myfile.tmp
+sudo mv /etc/myfile.tmp /etc/myfile
+rm /etc/myfile.tmp
+```
 
-Oneshot use:
+### wget
+
+Use wget to download the pre-compiled binaries:
 
 ```bash
-docker run -v ${PWD}:/workdir mikefarah/yq yq [flags] <command> FILE...
+wget https://github.com/mikefarah/yq/releases/download/{VERSION}/{BINARY} -O /usr/bin/yq &&\
+    chmod +x /usr/bin/yq
 ```
 
-Run commands interactively:
+For instance, VERSION=3.4.0 and BINARY=yq_linux_amd64
+
+
+### Run with Docker
+
+#### Oneshot use:
 
 ```bash
-docker run -it -v ${PWD}:/workdir mikefarah/yq sh
+docker run --rm -v "${PWD}":/workdir mikefarah/yq yq [flags] <command> FILE...
 ```
 
+#### Run commands interactively:
+
+```bash
+docker run --rm -it -v "${PWD}":/workdir mikefarah/yq sh
+```
+
+It can be useful to have a bash function to avoid typing the whole docker command:
+
+```bash
+yq() {
+  docker run --rm -i -v "${PWD}":/workdir mikefarah/yq yq "$@"
+}
+```
+
+### Go Get:
+```
+GO111MODULE=on go get github.com/mikefarah/yq/v3
+```
+
+## Community Supported Installation methods
+As these are supported by the community :heart: - however, they may be out of date with the officially supported releases.
+
+

+```
+choco install yq
+```

+## Known Issues / Missing Features
+- `yq` attempts to preserve comment positions and whitespace as much as possible, but it does not handle all scenarios (see https://github.com/go-yaml/yaml/tree/v3 for details)
+- You cannot (yet) select multiple paths/keys from the yaml to be printed out (https://github.com/mikefarah/yq/issues/287)

-<p>To convert output to json, use the --tojson (or -j) flag. This can be used with any command.</p>
-<p>Given a sample.yaml file of:</p>
-<pre><code class="yaml">b:
-  c: 2
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq r -j sample.yaml b.c
-</code></pre>
-
-<p>will output</p>
-<pre><code class="json">{&quot;b&quot;:{&quot;c&quot;:2}}
-</code></pre>
-
-<h3 id="json-to-yaml">Json to Yaml<a class="headerlink" href="#json-to-yaml" title="Permanent link">&para;</a></h3>
-<p>To read in json, just pass in a json file instead of yaml, it will just work :)</p>
-<p>e.g given a json file</p>
-<pre><code class="json">{&quot;a&quot;:&quot;Easy! as one two three&quot;,&quot;b&quot;:{&quot;c&quot;:2,&quot;d&quot;:[3,4]}}
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq r sample.json
-</code></pre>
-
-<p>will output</p>
-<pre><code class="yaml">a: Easy! as one two three
-b:
-  c: 2
-  d:

-                <p>Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file.</p>
-<pre><code>yq n &lt;path&gt; &lt;new value&gt;
-</code></pre>
-
-<h3 id="creating-a-simple-yaml-file">Creating a simple yaml file<a class="headerlink" href="#creating-a-simple-yaml-file" title="Permanent link">&para;</a></h3>
-<pre><code class="bash">yq n b.c cat
-</code></pre>
-
-<p>will output:</p>
-<pre><code class="yaml">b:
-  c: cat
-</code></pre>
-
-<h3 id="creating-using-a-create-script">Creating using a create script<a class="headerlink" href="#creating-using-a-create-script" title="Permanent link">&para;</a></h3>
-<p>Create scripts follow the same format as the update scripts.</p>
-<p>Given a script create_instructions.yaml of:</p>
-<pre><code class="yaml">b.c: 3
-b.e[0].name: Howdy Partner
-</code></pre>
-
-<p>then</p>
-<pre><code class="bash">yq n -s create_instructions.yaml
-</code></pre>
-
-<p>will output:</p>
-<pre><code class="yaml">b:
-  c: 3
-  e:
-    - name: Howdy Partner
-</code></pre>
-
-<p>You can also pipe the instructions in:</p>
-<pre><code class="bash">cat create_instructions.yaml | yq n -s -
-</code></pre>
-
-<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
-<p>When specifying a key that has a dot use key lookup indicator.</p>
-<pre><code class="yaml">b:
-  foo.bar: 7
-</code></pre>
-
-<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
-</code></pre>
-
-<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
-</code></pre>
-
-<p>Any valid yaml key can be specified as part of a key lookup.</p>
-<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
