 Postman collection converter
 Usage:
-    ./pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
-    php pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
-    composer pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
-    ./vendor/bin/pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]

+        ./vendor/bin/pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
 
 Possible ARGUMENTS:
-    -f, --file       - a PATH to single collection located in PATH to convert from
-    -d, --dir        - a directory with collections located in COLLECTION_FILEPATH to convert from
-    -o, --output     - a directory OUTPUT_PATH to put results in
-    -p, --preserve   - do not delete OUTPUT_PATH (if exists)
-    -h, --help       - show this help message and exit
-    -v, --version    - show version info and exit
+        -f, --file          - a PATH to a single collection file to convert from
+        -d, --dir           - a PATH to a directory with collections to convert from
+        -o, --output        - a directory OUTPUT_PATH to put results in
+        -e, --env           - use environment file with variables to replace in requests
+        --var "NAME=VALUE"  - force replace specified env variable called NAME with custom VALUE
+                              (see interpolation notes below)
+        -p, --preserve      - do not delete OUTPUT_PATH (if exists)
+        -h, --help          - show this help message and exit
+        -v, --version       - show version info and exit
 
-If both -c and -d are specified then only unique set of files will be converted.
+If no ARGUMENTS passed then --help implied.
+If both -f and -d are specified then only unique set of files from both arguments will be converted.
 -f or -d are required to be specified at least once, but each may be specified multiple times.
 PATH must be a valid path to readable json-file or directory.
 OUTPUT_PATH must be a valid path to writeable directory.
-If -o is specified several times then only last one will be applied.
+If -o or -e was specified several times then only last one will be used.
 
 Possible FORMATS:
-    --http   - generate raw *.http files (default)
-    --curl   - generate shell scripts with curl command
-    --wget   - generate shell scripts with wget command
+        --http   - generate raw *.http files (default)
+        --curl   - generate shell scripts with curl command
+        --wget   - generate shell scripts with wget command
+
 If no FORMATS specified then --http implied.
 Any of FORMATS can be specified at the same time.
 
-Example:
-    ./pm-convert \
-        -f ~/dir1/first.postman_collection.json \
-        --directory ~/team \
-        --file ~/dir2/second.postman_collection.json \
-        -d ~/personal \
-        -o ~/postman_export
-```
-### Notice
+Notes about variable interpolation:
+        1. You can use -e to tell where to find variables to replace in requests.
+        2. You can use one or several --var to replace specific env variables to your own value.
+        3. Correct syntax is `--var "NAME=VALUE". NAME may be in curly braces like {{NAME}}.
+        4. Since -e is optional, a bunch of --var will emulate an environment. Also it does not
+           matter if there is --var in environment file you provided or not.
+        5. Even if you (not) provided -e and/or --var, any of variable may still be overridden
+           from collection (if any), so last ones has top priority.
 
-Make sure every (I mean _every_) collection (not collection file), its folders and/or requests has unique names.
-If not, you can rename them in Postman or convert collections with similar names into different directories.
-Otherwise converted files may be overwritten by each other.
+Example:
+    ./pm-convert \ 
+        -f ~/dir1/first.postman_collection.json \ 
+        --directory ~/team \ 
+        --file ~/dir2/second.postman_collection.json \ 
+        --env ~/localhost.postman_environment.json \ 
+        -d ~/personal \ 
+        --var "myvar=some value" \ 
+        -o ~/postman_export 
+
+```
+
+### Notices
+
+1. Result of `pm-convert` execution is bunch of generated files.
+   Most likely they will contain errors such as not interpolated `{{variables}}` values (due to missed ones in collection),
+   wrong command format or `GET`s with bodies.
+   You must review any generated file before using.
+2. Make sure every (I mean _every_) collection (not collection file), its folders and/or requests has unique names.
+   If not, you can rename them in Postman or convert collections with similar names into different directories.
+   Otherwise any generated file may be accidently overwritten by another one.
+
+## How to implement a new format
+
+1. Create new namespace in `./src/Converters` and name it according to format of your choice
+2. Create two classes for converter and request object which extends `Converters\Abstract\Abstract{Converter, Request}` respectively
+3. Change constants values in your new request class according to format you want to implement
+4. Write your own logic in converter's `__toString()` method, write new methods and override abstract ones
